The events taking place on the geopolitical stage during the last decade of the Cold War – the 1980s – gave little indication of the imminent collapse of the Soviet-led Eastern Bloc (1989-1991). Correspondingly, looking at the amount of technology developed and deployed in the military field during the late, hi-tech stage of the Cold War, it is easy to notice that opponents on both sides of the Iron Curtain dedicated a significant (and even increasing) budget in preparation for a possible total confrontation. Reading papers and specialized books from the time, the outbreak of an open conflict, such to put a violent and abrupt end to years of opposition between the two opposing systems by recurring to nuclear warfare over the territories of Western Europe (most of them belonging to the NATO alliance, and all being substantially more militarized than today), was not deemed just likely, but more as a matter of time.

The БАРС system – The tropospheric network of the Warsaw Pact

In that era of extreme tension, it is not surprising that one of the most sophisticated and expensive assets developed and deployed jointly by all Nations in the Warsaw Pact, of course led by the USSR, came alive. History would cut its life short though, and as soon as the Warsaw Pact disintegrated, as a result of the opt-out from communist dictatorship of all Countries in Eastern Europe, this asset was decommissioned. This system was the tropospheric communication system ‘БАРС’, a Russian word reading ‘BARS’ and meaning ‘snow leopard’. The name stands as an acronym for four words in Russian, which translate into something like ‘Sheltered autonomous radio communication system’.

The idea put forward by the Soviet top-ranking military staff in the early 1980s (prior to the onset of Gorbachev administration) was that of a system capable of transmitting complex orders (not just simple signals, like for opening a bunker door or silo, but articulated messages) in a safe encrypted way, at a long distance and minimizing the chance of a complete breakdown even in case of an enemy nuclear attack. Despite being not new, the concept of a resilient and reliable system, such to allow exchanging significant amount of data without relying on cables, had been tested in earlier stages of the Cold War only for short-radius operations. Mobile transmitters/receivers, loaded on purpose-designed trucks, allowed for a reduction of the risk of a direct hit from an attacker, and for a quick redeployment in case of need. However, for the amount of data and range required for the coordination of a war scenario, involving many different Countries, and geographically encompassing an entire continent, a different system was required, capable of transmitting more massive data flows on longer distances, with a reduced risk of a sudden or complete interruption.

The БАРС system was based on a certain number of stations, scattered over the territory of the Countries of the Warsaw Pact. Each node was built as a bunkerized, manned military installation, featuring high-power, high-frequency fixed antennas emerging from the ground, and an underground shelter protecting all the technical gear required for manipulating the data to be sent or received, interfacing with the other existing local (i.e. national) networks for military and executive governmental communication, and of course managing the tremendous amount of energy required to pump a long-reaching signal into the ether.

Laying on the front line with the West, hosting a Soviet contingent of some hundred thousands troops (see here and links therein), aircraft (see here), missiles (see here) and nuclear warheads (see here), and being a key-ally of the USSR in case of the outbreak of an open war (at least until late 1989), the German Democratic Republic (or GDR, or DDR in German) was clearly included in the БАРС network from the initial drafting phase. Similarly, Poland, Czechoslovakia, Hungary and Bulgaria, and of course the Soviet Union (which included Belarus and the Baltics, and stretched west to Kaliningrad), all had БАРС stations on their territory. Stations were located at a range of a few hundred miles from one another, thus within the range required for each of them to communicate with one or more of the other nodes. Data (e.g. orders, reports or authorizations) input locally could be relayed along the network through intermediate nodes, down to the intended destination node. There were 26 nodes in total, of which four were in the USSR.

The Wollenberg site – Bunker 301 ‘Tushurka’

The GDR in particular had three stations built, all along the border with Poland, and located east of Berlin – namely Station 301 in Wollenberg, at the same latitude of Berlin, Station 302 in Langsdorf, towards the Baltic coast, and Station 303 in Röhrsdorf (near Königsbruck), not far from Dresden in the southeast of the GDR territory. The first among them, the Wollenberg site (codenamed ‘Tushurka’) could communicate with the other two national stations, as well as with Station 207 in Poland, from where data would be transmitted further down the network, towards the USSR.

The site was built by the GDR state, with technical hardware coming from several Countries within the Warsaw Pact, and most of the military hi-tech components manufactured in the USSR. The actual site (similar to its sister sites) was built in the frame of a highly secretive operation. The staff comprised about 60-70 men, the majority of which were military, where about 15% were civil technicians. Maximum security clearance was required, due to the top-secret nature of the installation and of the overall БАРС system. The bunkerized part of the installation was only a component of the larger premises of the base, camouflaged within the trees on the side of low-rising hill.

As pointed out, the immense spending required for setting up this multi-national hi-tech military communication system, which was extensively tested and completely commissioned (as a network) by 1987, did not save it from a quick demise and disappearance. In particular, Station 301 went definitively offline as early as August 1990.

However, the fate of the Wollenberg site was not so sad as that of many former Soviet or NVA (i.e. the East German Army) installations in the GDR. The high-power antennas were torn down, but except from that, little material damage was inflicted to the buildings and bunker on site. The place was basically shut-off and left dormant, until when a society of technically very competent local enthusiasts started a plan to preserve and open it to visitors, as a memorial specimen of the technology of the Cold War years.

A visit to the Wollenberg bunker site reveals a tremendous deal of interesting details, very uncommon to find elsewhere in the panorama of Cold War relics around Europe. Thanks to a careful preservation and restoration work, the bunker has most of its original systems still plugged to the grid and lit-up – some of them are reportedly still working! Even though the communication networks have been severed, the experience in the bunker is really evoking, and the atmosphere – with all the lit-up cabinets, lights, CCTV cameras, 1980-style screens, etc. – closely resembles that of the bygone era when БАРС was operative!

This report and photographs were taken during a private visit to the bunker, carried out in the Summer of 2023.

Sights

A visit to the the installation in Wollenberg starts from the original high-security access gate. As you may quickly notice when passing through it and getting a first view of the site, the state of preservation is exceptional. Except for the lack of military staff around, everything looks mostly like in the years of operation.

A group of soft-construction service buildings and a reinforced multi-entry garage constitute the first – and visible – nucleus of the installation. All buildings are painted in a camo coat.

A former building for the on-site staff has been turned into a permanent exhibition, with memorabilia items from the Cold War years, when the Nationale Volksarmee (or NVA, the Armed forces of the GDR) cooperated with the Soviet Red Army and the national Armed forces of other Countries in the Warsaw Pact.

A meeting room, now employed also for small gatherings, is especially rich of interesting and diverse items, including emblems, books, memorial plates and pennants, as well as TV screens, hi-fi systems and and beamers from the era.

Another room has been set-up as a control center for the base, with an original console and regional maps.

Compared to military bases (for aircraft or tanks), the Wollenberg installation is rather compact, with a main road giving access to most of the (not many) buildings on site, as well as the bunker. Actually, the bunkerized part was built under a low-rising hill, with the antennas originally standing on top of it. Access to the bunker is possible either by climbing uphill on the main road, or through a suggestive original pedestrian tunnel. The latter starts from within the service building itself, and – somewhat unexpectedly, for an underground installation – it climbs uphill, while keeping beneath the surface of the hill side slope. The lower end is guarded by an original CCTV camera.

At the top end of the tunnel you can find the actual access to the bunker. The design and reinforcement level conferred grade ‘D’ protection according to the military standard in use at the time, with grade ‘A’ being the strongest. Access is through an airlock, constituted by two tight doors at the opposite ends of a small vestibule built in concrete. This design allowed protection from the blast of a nuclear device.

Notably, the locking mechanism of the tight doors is Soviet military standard, which can be found in high-value installations like nuclear depots elsewhere in the Eastern Bloc (see for instance here in Poland, and here in Czechoslovakia).

To the visitor with some experience of Cold War installations, it will be apparent from the very start of the tour that the state of conservation of the bunker, including the systems in it, is exceptional, similar to the rest of the Wollenberg site. The original warning lights and the CC-TV camera for identifying people at the entrance are still in place.

Next to the entrance, a control room with technical gear for checking-in can be found – including original dosimeters for radiation and chemicals, mostly Soviet-made. Looking inside these devices is possible, and reveals a great deal of sophistication in the design and realization of the military-grade material from the time.

Showers and sinks for washing, as well as canister for disposing of contaminated clothes, are located in the same area.

Upon getting access to the sealed area of the bunker and passing by the decontamination facility, you find yourself on the top floor of the underground bunker. The high-technology gear required for the transmission/reception of data on the БАРС network, as well as the interface with other national communication systems, required for receiving data, issuing orders, etc. over the territory of the GDR, were located on this floor.

Two symmetrically placed rooms host two twin transmission centers for the БАРС system. A single manned console can be found in each of them, surrounded by electronic cabinets and switches. At a closer look, all the material herein is Soviet made, and labeled in Russian only.

On the wall ahead of the console station is a set of cables, communicating with the antenna and allowing to set the orientation and monitoring its status.

The actual signals transmitted to the antenna, or received from it, traveled along special hollow ducts, with an almost rectangular section. Bundles of these ducts can be found in the ‘Sender’ (which means ‘transmitter’ in English) room, immediately next to the room where the manned console is.

The modulation and demodulation of the signals going out and coming in respectively through the antenna on top of the bunker required some special pieces of electronics, which included the Soviet-designed KY-374 klystron (codenamed ‘Viola’), a component to be found in the cabinets of the ‘Sender’ room.

Following the hollow ducts, it is possible to find where they finally exit the usually manned part of the bunker, bending into receptacles and leading outside. Piping related to other systems, including air conditioning, can be seen as well crossing or running in the same narrow technical corridors.

Beside the consoles monitoring the antenna and the data flowing through it, a kind of operative room for communication can be found, where consoles allowing to receive and forward data and communication to/from all systems are on display. This largely original room features consoles of different levels of technology.

Original explanatory schemes showing the basic features of the БАРС system are on display in that area – in Russian!

An adjoining room features the cabinets required for making all these system work. The cabinets are really many, with a significant share of material manufactured in the USSR. The sight of all these cabinets together is really impressive, and tangibly provides the feeling of a high technology, sophisticated and expensive design. It compares well, but in a largely up-scaled fashion, to the electronics to be found in some special communication bunkers on the western side of the Iron Curtain (see here).

Interspersed with the original arrangement of the cabinets and consoles are some displays of original material. These include specimens of different types of cables for signal transmission – some of them hollow and pressurized, others featuring impressive bundles of thinner wires – the KY-374 klystron, and other once top-secret core components of the БАРС transmission system. Also on display is one of the few remaining parts of the original system of antennas, once on top of the bunker. The antennas were the only part to be physically torn down when the system was decommissioned, upon the demise of the Warsaw Pact and the end of the Cold War.

The bunker was manned by military and technical staff 24/7. Furthermore, as typical for bunkers from the Cold War era, provision was made at a design level to allow the staff to live isolated within the bunker for an extended period of time, in view of the eventuality to face a nuclear fallout scenario.

On the same floor as the technical rooms, the commander of the station had his own private room. This is still adorned with typical Soviet iconography, as well as everyday material from the age when the bunker was operative.

A small canteen, with a kitchen and a modest living room, can be found at the same level. An original storage room has been employed to gather examples of everyday products, like soap, skin care cream, etc., as well as canned food, cocoa, and beverages of all sorts.

This represents a very rich catalog of now largely defunct and forgotten labels, from the age and regions of the Eastern Bloc (and especially from within the GDR). Also on display are bottles of spirits, likely still very good!

The visit proceeds then to the lower floor, which can be reached through a flight of metal stairs.

The lower floor host the plants required for the regular operation of the entire bunker, such to guarantee operational ability even in case of an enemy attack carried out with nuclear, chemical or biological warfare. The air filtering and conditioning system is very modern. Beside typical filtering drums for particles, to be found also in other bunkers (see for instance Podborsko here), you can see a bulky filtering and climate conditioning system, neatly arranged within two parallel square-shaped ducts. Filtering against chemicals as well as biologic agents was carried out employing special active filters.

Sensors for the level of contamination of the bunker air can be found in different rooms. Much material here is standard Soviet-made.

Systems for water pumping and compressed air can be found as well, including compressors, pumps and reservoirs. Looking at the always interesting factory labels in this area, it is easy to find export products of Bulgaria, Romania and other communist dictatorships of the era. Of course, much hardware is also manufactured in the GDR.

Electricity was supplied from the outside grid, yet capability for self-sustaining in case of a grid loss (for instance in case of war) was implemented as well. Three big German-made Diesel generators have been put in place, and are still in an apparently good condition.

Another example of the high technological standard reached in the late Cold War era is represented by the control room for the plants within the bunker. A manned control station, with a console and a direct view of lit-up cabinets, reporting the status of the various systems running in the bunker, compares well with control rooms of large industrial plants in operation today.

Carefully kept in its original status, with many of the electric links and cabinets still working, the sight of this room is especially evoking.

Also on the lower floor are the sleeping rooms for off-duty staff. Typically, this was not employed except for drills, when the bunker could be sealed to simulate operations in case of the outbreak of hostilities.

Back to the upper floor, it is possible to exit the bunker via a stairway and through a side gate. You will find yourself on top of the low-rise hill where the bunker has been dug. Here the concrete base of the crane where the БАРС antenna used to sit are still visible. Notably, these antennas were much smaller than the tropospheric antennas employed for the TROPOSCATTER system of NATO. This was the result of a different bandwidth employed for transmissions. Therefore, even in the days of operation, the antennas on top of the bunker were not as sizable as those of TROPOSCATTER installations (which were enormous in size).

Looking closely, in the top area of the installation, the duct for supplying the Diesel oil tank of the bunker can be found, similar to sensors for radiation and other atmospheric parameters (similar to what can be found also in other nuclear-proof bases, for instance here). These allowed to monitor the conditions of the outside air, detect an attack and trigger or manage the sealing of the bunker in case of need, by locking all the tight doors.

This access to the bunker is fenced by the original electrified fence, severing this area from the rest of the installation through a further layer of security.

All in all, a visit to the Wollenberg bunker offers an incredible insight in a fascinating and crucial field of warfare – data and communication exchange – as well as a lively and evocative display of a late Cold War hi-tech installation from the Soviet side of the Iron Curtain!

Getting there & Visiting

The German name of the Wollenberg bunker is ‘Militärhistorisches Sonderobjekt 301 Wollenberg’. It can be reached very easily with a car. It can be found in the open countryside along the regional road 158, driving about 35 miles (about 1 hour) northeast from downtown Berlin towards Poland. The exact location is between the small village of Höhenland (~4 miles) and the more sizable Bad Freienwalde (~6 miles). There is a large parking area immediately next to the road, giving direct pedestrian access to the premises of the former military installation. Despite being placed very conveniently, the site is rather elusive when passing by, since it is hidden in the trees and not directly visible from the road. The address corresponding to the place in Google Maps is Sternkrug 4, 16259 Höhenland. The inconspicuous village of Wollenberg, giving the name to the installation, is just nearby, but it is not crossed by the regional road, and it should not be employed for pointing this destination with a nav.

The Wollenberg bunker is a listed historical installation. It is perfectly maintained, privately managed, and it can be regularly accessed with guided tours. These are offered typically one day per week in the summer, or by prior arrangement. Possibly the best option for getting the most out of your visit is getting in contact with the group of very knowledgeable enthusiasts running the place. The official website is here (do not be discouraged by the ‘static’ appearance of the website, they are very active, and they shall typically answer your inquire).

My visit was planned by initiative of Dr. Reiner Helling (see also here), and we visited in a group of three, including the guide (Dr. Michael Schoeneck, a former engineer, with a profound knowledge of any technical aspects related to this installation), which happened to be a perfect option for touring also the narrowest receptacles of the bunker. Visiting in groups too big may be not advisable, since the rooms and corridors are rather narrow, and the place may turn overcrowded for interacting with the guide and for taking good pictures. I think the visit – including the technical content – may be tailored to the needs of the audience. For technical-minded subjects, historians and former military, a visit may take about 2-3 hours (the latter was my experience). In my case, the guide could understand but not speak fluent English, yet Dr. Helling could translate with ease all the explanations. Of course, if you have at least a basic knowledge of German and of the technical material you are looking at, this may simplify your visit, which is in any case highly advisable for those interested in military technology and the Cold War.

Preserved Cold War Bunkers in Northern England

The central role taken by Britain in WWII, firstly containing and then countering the expansion of the Third Reich, is duly and proudly celebrated all around the Country, with memorials and thematic exhibitions, often hosted in historical locations, regularly open for a visit.

The United Kingdom joined NATO as a founding member in 1949, and had already been at the forefront of a European anti-Soviet alliance with France since 1947. The strategic political and military ties with the US, pivotal in putting and end to WWII in Europe, were kept over the following decades, against the menace constituted by the Eastern Bloc. Thanks to its geographical position, and bolstering a nuclear arsenal, strategic bombers and submarines of its own, Britain was a major player of the Cold War.

Despite that, the Cold War left behind comparatively less memories than WWII, with only a handful installations open to the public, and somewhat out of the spotlight. In this regard, this reflects an attitude generally widespread in Europe towards the traces of the second half of the 20th century.

However, for people with an interest in the Cold War age, and more in general for those with a thing for (especially nuclear) warfare technology, there are two really unmissable sights in Northern England, which make for a vivid hands-on experience of the ‘era of Soviet threat’.

One is the Hack Green Secret Nuclear Bunker, with a fascinating history starting in WWII and spanning the entire duration of the Cold War. Here one of the finest collections of nuclear-war-related material in Europe can be found, together with much additional material from the era, in a largely preserved historical site.

Another is the York Cold War Bunker, built in the Cold War age to provide protection to the staff of the Royal Observation Corps (ROC) in case of a nuclear attack, as well as the ability to help coordinating fundamental public functions – health, transportation, food and energy supply, etc. – in a post-attack nuclear fallout scenario.

Both sites are regularly open for a visit, and provide a vivid testimony of civil and military plans and facilities seriously prepared in England for a nuclear apocalypse scenario.

Hack Green Secret Nuclear Bunker

The Hack Green site is located deep in the Cheshire countryside, about one hour driving south of Manchester. Actually, it is in a really secluded location, far from any sizable urban center, and away from major roads. Even today, when this facility is working as a top-level museum, some attention to the signs is needed to reach the site.

Once by the gate, you are immediately driven back in time by the appearance of the tall military-style external fence with official government signs, and by the blunt and in impenetrable appearance of the big concrete bunker – what you see is only the part above ground level! – with a big antenna protruding from the top. Nearby, you can see an apparently still off-limits area, with a now-dead radar antenna and an old Jet Provost trainer in RAF colors.

History

The history of the Hack Green site dates to as back as WWII, when it was established as one of the 12 most developed Ground Controlled Intercept (GCI) centers, out of 21 total nodes in Britain. Essentially based on the airspace scanning radar plants available at the time, the so-constituted ‘Chain Home’ surveillance system was operated by the RAF, and intended to track intruding German aircraft, thus directing air force planes against them. Radar aerials appeared on site at the time, suitable against relatively slow moving propeller-driven aircraft of those years.

With the start of the Cold War, and the need to reconfigure the defense against the USSR and Warsaw Pact forces operating with jet-powered aircraft of increasing speed, several modernization plans were started in Britain, aimed at implementing more effective detection and threat-countering radar technology, like ‘Green Garlic’, and later ROTOR. The latter called for the institution of a chain of detection nodes, not much dissimilar in concept from the older ‘Chain Home’ of WWII, but much more articulated, efficient and technologically advanced. At the time one of the most expensive government-funded operations ever, 66 installations were implemented all over Britain within ROTOR before the mid 1950s, with different roles in the network. The bunker you see today on the Hack Green site was one of them.

Keeping up with the fast-developing offensive technology of the 1950s and 1960s required a continuous update of the defensive network, in particular asking for the addition of intercontinental missiles to the enemy arsenal to counter. The US-led ‘Ballistic Missile Early Warning System’ (BMEWS) included 12 early-warning radar stations around the Atlantic, including a single station in the UK (RAF Fylingdales, Yorkshire, still in operation today). Before BMEWS went operational (early 1960s), triggering a re-organization of all other defense radar systems by the time obsolete, Hack Green took an interim role as one of only 4 radar stations operated by the RAF monitoring all military and civilian traffic through the British airspace, coping with new fast jetliners. The name of the Hack Green radar site in that stage was ‘Mersey Radar North’. Finally, in 1966 the RAF released the site to the government, which put it in mothballed status.

It was in 1976 that a new life began for Hack Green. Starting in 1958, the Home Office invested much in the preparation of an emergency structure, capable of keeping of managing a post-nuclear attack scenario, and keeping the basic public functions active. In the event of a total nuclear war, a failure of the national hierarchy and military chain of command was forecast, as a result of an extensive damage to the infrastructures and communication systems. In order to recover as fast as possible in such an emergency, the UK would split in 11 regions, each with a regional seat of government (RSG). In the region, a civil Regional Commissioner would take a leading administrative role, and would be responsible for coordinating disaster recovery operations, like supplying medical resources, food, water, and reconstructing infrastructures, while waiting for the national government to reactivate its functions. The Commissioner would be aided by the UK Warning and Monitoring Organization (UKWMO), which took over the function and organization of the older Royal Observation Corps (ROC) established during WWII. This structure was further potentiated in the 1960s and 1970s, also introducing a similar regional scheme for the military in case of a nuclear attack.

The seat of the RSG was in the Regional Government Head Quarters (RGHQ). Following some years when it was hosted in Preston, then in Southport, north of Liverpool, the RGHQ for the 10th region (then 10:2, following a split in two halves of this large region) found its home in Hack Green. The former radar facility was potentiated enormously, and set up with the ability to host 160 civil and military staff for 3 months without resupply in case of a nuclear attack on the UK.

Within the framework of the emergency plan for a nuclear attack, the RGHQs all over the UK went on operating until the demise of the USSR in December 1991, to be soon deactivated over the following years. Hack Green was scrapped of all content, and put up for sale in 1993. It was privately acquired in the mid-1990s, and carefully restored in some parts, or being stocked with interesting material from the Cold War era in some of the many rooms.

A tour of the bunker

Access to the bunker is via a concrete slide, and through a metal gate. Originally the male civil servants dorm, the first room you meet is now a kind of storage for items recently incorporated in the collection. These include a jeep, a model of an Avro Shackleton, and interestingly a nuclear warhead. The original system to activate the rooftop antenna is in a cabinet along a sidewall.

The ticket office and canteen are now in the original canteen area of the Hack Green site. Restored to a 1960s appearance, parts of the kitchen furniture are original from the site. Along the sidewalls are several memorabilia items, including some original Soviet emblems, not unusual today in museums on the other side of the Iron Curtain (see for instance here), but hard to find in the UK.

An adjoining room reproduces the environment where the ROC would have worked in case of a drill or real nuclear attack. Among their function was the pinpointing of nuclear explosions. The forecast and monitoring of the fallout is strongly bound to the local weather and winds. This was kept under surveillance through reporting stations scattered on the UK territory (more than 1 thousand), which transmitted information to Hack Green and other RGHQ and UKWMO bunkers (see the York bunker later in this post). They could then coordinate recovery operations, avoiding extreme exposure to radiation of the emergency staff.

Monitoring was through dedicated sensors, and communication through specific transmission gear. Two display cases in the same room feature interesting instruments, training documents, and memorabilia items from the rich history of the ROC, documenting also their activities in WWII.

Ground floor

The Hack Green bunker largely retains its original arrangement. It is composed of a ground and an underground floor. Along the main corridors are interesting examples of the papers produced by the UKWMO, and by the civil defense service during the Cold War. Among them, are leaflets for the population, with best practices in case of a nuclear attack.

Also interesting are more technical posters from the era, either outlining the role of the public organizations monitoring a potential nuclear apocalypse scenario, or providing technical details on the effects of nuclear weapons – what to expect in terms of damage or health issues, depending on the type and local condition of a nuclear explosion.

For sure a focal point in the exhibition of Hack Green today is the display of nuclear warheads, and nuclear-related material. Hosted in a room previously employed by emergency staff, the exhibition retraces with original material, mock-ups, rare pictures and videos, the history of the British nuclear arsenal, managed by the Atomic Weapons Establishment (AWE).

The WE177 was designed to constitute the backbone of the air-dropped nuclear deterrent of the UK. Examples of this bomb are on display together with technical material employed to monitor their status and manage launch or drills. In service between the 1960s and the 1990s in association with larger strategic bombers like the Vulcan, or smaller fighter-bombers like some versions of the Harrier or Jaguar, it could be assembled in some different versions, sharing the same baseline construction, but with nominal yields ranging between 10 to 450 kilotons.

Also on display are pictures and mock-ups of the old Polaris warhead, together with the original casing employed to transport this 200 kilotons item! A US design, the Polaris was acquired by the UK in 1963, to supply the Royal Navy and constitute the UK underwater deterrent. The Polaris missile featured a three-warheads fuse, bearing a total yield of 600 kilotons.

A very rare artifact is the warhead of project Chevaline, a British design to improve the potential of the Polaris, which saw limited service with the Royal Navy in the 1980s. The Polaris/Chevaline was replaced by the Trident missile system, still employed today in the nuclear deterrent role.

Besides the central exhibition of nuclear warheads, the display cases in the same room offer a wealth of super-interesting technical gear and memorabilia related to nuclear weapons. These include components and cabinets of radio and radar systems, to be transported on board aircraft or to be employed on the ground. These parts come from different ages, and from several Countries, including the Eastern Bloc – for instance, a very rare Soviet suit to work on high-power radar antennas for maintenance. Powerful radars actually emit rays with a high power-over-volume (power density) ratio especially in the vicinity of the emitting apparatus. This may even turn deadly for humans (roughly like being in a microwave oven would be!), and precautions are needed when working in such environment.

A really unique collection on display is related to Geiger counters and dosimeters. These include environmental and personal use devices, from various ages and nationality.

Two display cases are dedicated to material coming from beyond the Iron Curtain, most notably from the USSR and the GDR! It is really hard to imagine how this material could manage to come to Hack Green.

Part of the display is dedicated to the civil defense corps of different Countries, with helmets, emblems, papers and uniforms, showing how similar actions in preparations for a nuclear war were carried out in many Nations of continental Europe, also in the Eastern Bloc. Actually, a very close relative of the UKWMO RGHQ control center, with a totally similar function, can be found in a perfectly preserved condition in Poland (see this post).

More memorabilia items come from the history of civil defense in the UK. Among the most rare artifacts are the only surviving example of the ‘Queen’s telephone’, which was employed for enforcing the Emergency Power Act, which among other things may have transferred power to the Regional Commissioner. There used to be one such phone in each of the RGHQ, but all were destroyed for security reasons following the shut-off of the bunkers, except this one, and the one at the other end of the line – in the Royal residence.

An adjoining room hosts a reconstruction of the radar screen room from the age Hack Green was employed as a radar station managed by the RAF. All panels are lit, providing a vivid, pure Cold War experience!

To the end of the main corridor, you can reach another entrance to the bunker, which is nowadays normally shut. However, this used to be the main entrance, and close to it are the control room of the bunker and the decontamination area.

The control room is not accessible, but the large windows allow to take a glance to its original appearance. It is still employed to control electric power and air conditioning. Manned nuclear-proof bunkers are customarily pressurized, sucking contaminated air from the outside, which is carefully filtered for poisons and radioactive particles, and pumping unfiltered bunker air to the outside (see this post for another example in a Soviet bunker).

People entering after work out in the fallout-polluted environment were decontaminated through showers, and used anti-radiation suits were left in an isolated sink still on display.

Before leaving the ground floor, you can find on the ground level the female dorm for the staff of the RGHQ bunker. In the same room, an original system for communicating on the very low frequency bandwidth has been put on display. This Cold War relic could be employed to issue orders to the strategic submarine force. This very cabinet was employed by Prime Minister Thatcher for ordering the attack against the Argentinian ship General Belgrano.

A final room on this floor is the sick bay, sized for the staff of Hack Green only, but equipped to manage health issues resulting from the exposition to a nuclear attack.

Underground floor

Descending to the underground floor is possible via the original stairs. The first room you meet features an exhibition of original Soviet uniforms, belonging to some high-ranking officials from various branches of the Red Army. Really hard to see in this part of the world, their origin is well documented.

Close by, is a small display of military material from the Soviet bloc, ranging from original weapons, to communication systems, emblems and instructional posters for the troops (similar to what you can find in dedicated museums in former Warsaw Pact Countries, like here or here).

Nearby is a communication room originally employed by the military staff of the bunker, working in parallel with civil servants in the management of the nuclear emergency. Original radio transmission gear of military standard is still in place.

Before entering the core preserved area of the bunker, i.e. the rooms of the RGHQ, you can find the original water and air supply systems, and the corresponding technical cabinets, in a big room on the underground level.

The rooms of the RGHQ are all interconnected, and located to the side of the corridor on the underground floor. The way they look is from the days of activity of Hack Green as a RGHQ, i.e. the 1980s. Typical Cold War technology from the time is featured in this area.

Firstly, you enter the warning room, which used to be the contact point of the RGHQ with the national surveillance system. By design, the BMEWS at Fylingdales should have picked up an incoming ICBM within 30 seconds from launch, spreading an alert signal at all levels. This would have been received here and by the entire civil defense system within 90 seconds. This would leave roughly 4 minutes (out of a total of around 6 minutes for the missile to come to Britain from the Eastern Bloc) to tell the population of the incoming missile, which would happen through some thousands sirens scattered around the UK. The physical alarm signal management system was called HANDEL, and was employed from the 1960s to 1992. The apparatus on display at Hack Green, a node of HANDEL, is notably still working, albeit disconnected.

The warning room can be accessed directly from the Commissioner’s room, both an office and private room. Original maps and furniture can be found in this room, the only private one in the bunker. Immediately next to it is the cipher office, a communication office connecting – at least in non-emergency conditions – the center with the external world. Ciphered language was employed for safe communication with governmental offices, both domestic and abroad.

Next are a conference room, for meeting within the staff of the RGHQ, and a broadcast studio. The latter was focused on radio broadcast instead of TV, since the latter would not work in case of a nuclear attack. The idea was for the Commissioner to communicate directly with the administrative region, possibly repeating messages of national significance, or instructing about local disaster recovery actions, evacuation operations, etc.

The tour goes on with a very interesting area, stuffed with original electronic and communication material. Communication from the bunker to the other similar bunkers withing the UKWMO was possible through a dedicated system called Emergency Communication Network (ECN). The main function was that of constantly updating the map of the fallout and of the operations taking place at all levels, including all surviving infrastructures. Many maps and teletypewriters, original components of the system, are part of the display.

The ‘brain’ of the system was the Message Switch Exchange (MSX). A top-tier system elaborated by British Telecom in the 1980s, it looks exceptionally complex. The lit cabinets and modules provide a really vivid impression of how it should have looked like back in the Cold War years. The electronic cabinets and wiring driving to the rooftop antenna are still lit as well.

A rare, incredible portable satellite communication antenna is on display. This was employed in peacetime condition, and stored inside the bunker when under attack.

The screens where the meteorologists and nuclear scientists displayed all the information gathered and prepared forecasts are another unusual Cold War sight.

Perhaps unexpectedly in a 1980s hi-tech environment, a purely analog, wired telephone exchange system is on display. This is original as well, and was kept in service as a ‘last line’ backup system within the ECN until 1992, should the futuristic MSX system fail under an attack.

A complement to the exhibition of the RGHQ is the fire control room, where a big screen and several communication consoles were employed for directing firefighting actions at a regional level. Following the experience of Nagasaki and the extensive nuclear tests of the 1950s, it is known that fires resulting from the extreme temperature and radiation intensity associated with a nuclear explosion are possibly even more dangerous to buildings and infrastructures than the shock-wave itself.

A display which is not original from Hack Green, but found an ideal home in this bunker, is made of a reconstructed room from the Regional Air Operation Center (UKRAOC), which would gather information from the BMEWS. The material on display used to be at RAF High Wycombe, where the UKRAOC facility was located in the Cold War years.

Fed by the BMEWS early warning station at Fylingdales, the apparatus in this room was constantly updated on the defense situation. A Soviet ICBM attack would be detected here, and from here the alarm signal to the entire national civil and military defense system would be triggered. This really one-of-a-kind reconstruction is really evoking, with the original panels all lit, and a dim light background!

A final room on the underground floor hosts a reconstruction of a Soviet missile launch room. Perhaps not accurate as a reconstruction, it is however centered on original material and memorabilia items from the Soviet bloc. This area has been employed as a set for movies.

At the base of a second stair well ascending to the ground floor you can find a reconstruction of one of the more than 1 thousand peripheral posts of the ROC. Such posts, scattered on the UK territory, gathered information for the RGHQ, and constituted the ‘sensors’ of the nuclear attack detection network. The technical gear includes over-pressure and radiation intensity transducers.

Getting there and visiting

The bunker is in a very secluded location, about 25 miles west of Stoke-on-Trent, and roughly 60 miles from Liverpool and Manchester. Very little advertised in the area, and not much known to the general public even in the UK, this hidden gem can be reached very conveniently by car, not much conveniently with public transport. The exact address is French Ln, Nantwich CW5 8BL, United Kingdom.

The bunker was built far from the crowds. Do not be worried as you see the road getting narrower and you feel like your NAV is taking you to nowhere – you are probably on the right path! Once there, you will find a large inside parking, and a top-level management of the entire facility.

Visiting is on a self-guided basis, with tons of explanatory panels and illustrations allowing to make the most out of your visit even if you have just a normal interest and preliminary knowledge of the topic. For a specialist, this super-interesting, one-of-a-kind site may require at least 2 hours for capturing the details, and possibly take pictures. Website with visiting information here.

York Cold War Bunker

Besides the impressive Minster and the beautiful historic town, York has the distinction of being the seat of one of the few Cold War bunkers preserved in the UK. Differently from Hack Green (see above), the bunker in York was installed relatively late in 1961, in the middle of the Cold War. Since then and until the collapse of the USSR, it acted as a node in the UK Warning and Monitoring Organization (UKWMO), collecting information and coordinating emergency actions around York in the event of a nuclear attack. A cluster of reporting points was linked to the bunker in York, which took the name of Headquarters of the N.20 Group within the UKWMO.

An eminently intelligence collection and information relay facility, the bunker was manned by the Royal Observation Corps (ROC), who provided voluntary civilian staff to support the monitoring and communication functions of the bunker in the UKWMO network. The bunker ceased operations and was basically sealed in 1991. Until that time, the ROC ran the facility, carrying out regularly scheduled drills and simulations. The bunker was designed and sized to offer its staff a self-support ability of a few weeks in a nuclear fallout scenario. Besides all supporting facilities, including water tanks, pumps and power generators, the facility was centered on a set of sensors for nuclear blast detection, as well as provision for fallout forecast and monitoring.

The bunker has been taken over by the English Heritage, a structured nationwide historical conservation association, which restored the site and opened it to the public.

The York Cold War Bunker is not far from the historical center, yet in a quiet residential area. Access is from a small parking area among low-rise buildings. The greenish paint of the concrete walls and the tall metal antenna on top cannot be spotted from much farther away than the parking itself. Curiously, the pedestrian door of the bunker stands some feet above the ground, and can be reached via a concrete stairway. Then once on top and inside, you need to descend some flights of stairs to get underground.

Compared to the Hack Green bunker, the York group headquarter is more cramped, with smaller rooms, lower ceilings and narrower corridors.

The first part of the visit covers the supporting facilities. These include a ventilation system, which as customary for nuclear-proof bunkers (but the same is true for older bunkers dating from WWII) filtered the incoming air and ejected the inside air, basically pressurizing the bunker environment with respect to the outside atmospheric pressure. This avoided passive ingestion of contaminated air from the outside.

A power generator and a water pumping system are also visible. A control panel for all the plants has been preserved, similar to the machinery in this area, dating from the time of construction.

The centerpiece of the visit is of course the reporting room. The reason for putting a headquarters in relatively low-sized York was the presence in the area of significant food production industries, as well as of a major railway node in Northern England. Furthermore, military facilities like the only BMEWS station in the UK happened to be in Fylingdales, northern Yorkshire. These features would make York a valuable strategic target for an attacking enemy. The main function of the bunker within the UKWMO was that of ascertaining the position and intensity of a nuclear explosion on the territory covered by its jurisdiction.

Anticipated by the early warning ballistic missile detection system protecting the UK, the hit could be recorded by the sensors available in the bunker or in other reporting points scattered around in the country. The bunker would then try to predict and follow the evolution of the fallout. This would allow coordinating emergency and recovery actions including fire suppression, medical evacuation, water and food transport and supply, etc.

The central reporting room looks mostly like an operations room in a military headquarter. It is structured on two levels, with large maps and boards for visually updating the situation and writing information. Batteries of telephones and teletypewriters allowed obtaining communications and sending updated information to allow emergency services as well as decision centers to carry out post-attack operations. This system was not dissimilar from the counterpart beyond the Iron Curtain (see for instance this center in Poland).

Nearby the reporting room, the components of the sensor suite allowing to detect the position and intensity of a nuclear explosion are on display.

The first is the bomb-power indicator (BPI). The working principle is that of reading the over-pressure caused by the shock-wave invariably produced by an explosion, and particularly intense for a nuclear explosion, releasing an immense amount of energy in a small volume and within a very short time. The supersonic traveling shock-wave is responsible for the mechanical breaking of building and superstructures, like antennas, suspended power lines, bridges, piers, etc. Being a wave of pressure, its intensity can be measured by pressure transducers, which for the BPI show the reading on a simple analog dial.

The transducer, seen handing from the ceiling in the exhibition, would stand on the rooftop of the bunker, exposed to the explosion. This type of sensor was also installed in smaller reporting points scattered over the territory of the UK.

A second sensor was the ground zero indicator (GZI). Here the working principle was also very simple. The main element in the GZI is a metal drum with a small hole in the side, and a piece of photographic paper covering the inside surface of the cylinder. An explosion would send a high-energy light beam through the hole, producing an impression on a precise point on the paper. By positioning in a very accurate way the drum on its pedestal on top of the bunker, according to a precise fine-tuning, it was possible to retrieve the direction of the incoming beam. By composing the reading of more than one precisely-located drum, it was possible to pinpoint the position of the explosion by triangulation, both in terms of geographical position and altitude. The latter is a very relevant practical information, since for instance the quality and hazard of the fallout are strongly related to the proximity of the explosion to the ground.

The GZI, a purely analog sensor, had the odd feature of requiring collection of the photographic paper by venturing outside of the bunker after and explosion, i.e. facing the fallout.

The third and most evolved system on display is an AWDREY computer. The name stands for Atomic Weapon Detection Recognition and Estimation of Yield. This artifact is very rare to see, and a quite refined piece of engineering for the time. It was supplied to 12 headquarter bunkers of the UKWMO, including York, and was operative from the early 1970s. The computer is the computational part of the system, whereas the detection system was based on a sophisticated transducer put outside, on top of the bunker. The working principle was much more sophisticated here, and related to the evolution of the intensity of the radiation coming from the core of the explosions in the first instants of the detonation process. Several stages of a nuclear explosions happen in a row on a scale of a few millionths of a second. These include a predictable oscillation of the intensity of radiation. The exact features of this oscillation are correlated to the yield of the explosion. The ability of AWDREY to collect and interpret data from the early stage of the explosion would allow it to reconstruct the position and yield of the explosion at once.

Tuned on experimental data from nuclear testing in the field, this system delivered good general performance, with some inaccuracy in case of intense atmospheric phenomena taking place – or during fireworks, when the York system was apparently misled in one occasion, interpreting it as a Soviet attack!

The tour is completed with a view of the dorm for the civil servants of the ROC, and with a short exhibition on some historical and political aspects of the Cold War.

Getting there and visiting

The York Cold War Bunker is professionally managed by the English Heritage. Visiting is only possible with a guide. Please note that as of 2022, pre-booking is strictly necessary, since there is no ticket office on site. The guided tour lasts about 45 minutes, including a well-crafted introductory video. At the time of writing, only the first underground floor is open for a visit, but plans for an expansion of the visible part of the facility are being drafted.

The tour is very interesting and detailed, with some educated humor to make it more enjoyable! For specialists, it will be too quick, especially if you like to take pictures. However, the site indeed deserves a careful look also for the more technically-minded people, especially considering the little number of similar facilities open in Europe – and of course in the UK, where it is a one-of-a-kind destination, and a true must for Cold War historians.

The location is about two miles west of York Minster. Convenient to reach by car, several public parking lots are available in front of the gate or in the neighborhood. The exact address is Monument Cl, Holgate, York YO24 4HT, United Kingdom. Website with full information here.

Aircraft Collections in Norway

The ‘Norwegian chapter’ in the book of aviation history is a peculiar and interesting one. Similarly to virtually every Country in the western world, in the early age of aviation small manufacturing companies appeared also in Norway. Despite meeting with little success in the long run, they contributed in creating momentum around those ‘novel flying machines’. Norway, with a sinuous coastline stretching for some thousands miles from the latitude of England up north to where the European continent ends, and with a land largely covered in snow for many months per year, has been an ideal place for the development of a local air network since the early days of aviation. This created an alternative link between smaller communities and industry centers. As a matter of fact, similarly to Greece, Norway is among the top employers of smaller aircraft for commercial routes in Europe still today.

To the same early era belong the now almost mythological arctic expeditions, carried out also by air – by plane or airship – and almost invariably departing from Norway. The well-known Norwegian explorer Roald Amundsen was an advocate of air explorations, and his primary contributions to geographical explorations have constituted in some cases milestones in aviation history.

Despite a significant down-scaling of its Armed Forces in the post-Cold War scenario causing a strong reduction of the military presence in the Country, Norway has been in the focus of massive military operations since the 1930s.

In particular, both its geographical position and natural resources met the appetite of the Third Reich, which successfully invaded Norway in a blitzkrieg campaign in late spring 1940. Through an action based strongly on airlift capacity, German cargo planes relocated personnel and material very effectively to Norway. The crown and government were forced into exile in Britain, and with it also the military chain of command. Actually, the air force academy was moved to Toronto area, Ontario, where the military facilities of Norway got the name of ‘Little Norway’. New Norwegian pilots were relentlessly trained there, preparing them to repel the enemy from their Scandinavian motherland.

The Third Reich managed to keep a grip on southern Norway until its collapse and the end of WWII in Europe. Having witnessed the failure of neutrality as a foreign policy, in the rapidly deteriorating post-WWII scenario and the beginning of the Cold War between the Soviet-led eastern bloc and the free democracies of the western world, Norway joined NATO as a founding member.

Since then and for more than four decades, Norway was on one of the ‘hot’ fronts of the war, with a border-crossing point with the USSR, and a privileged position to patrol the skies over the shipping routes leading from the highly-militarized Kola peninsula into the Atlantic Ocean (see this post). Keeping a constant watch on the air, surface and submarine movements of the USSR was a task brilliantly covered by the Norwegian Air Force and Navy for the entire duration of the Cold War.

Today, western world issues like climate-related hysteria and hardly shareable, deeply ideological so-called ‘carbon neutrality’ policies promise to definitively clip the wings to sport, private and commercial aviation especially in this Country, through an unprecedented technological leap back. Similarly, the (today, so evidently) short-sighted post-Cold War dismantlement of military power in Europe has impacted military forces also in Norway.

However, the memory of the glorious years when this proud Scandinavian Nation has been on the forefront of aviation technology and in the focus of military action are duly relived in two wonderful aviation collections, celebrating what can be achieved through technical skill, courage and good national ideals.

One of these collections is the Norwegian Aviation Museum, located east of the airport of Bodø, a coastal town on the Norwegian Sea, not far north of the Polar Circle. The other is the Norwegian Armed Forces Aircraft Collection, located just west of Oslo-Gardermoen Airport, in the south of the Country and close to the capital city. Both museums host world-class collections, really worth a detour for aviation-minded people from whatever continent, and for the general public as well, as can be possibly perceived from the pictures in this post.

Photographs in this post were taken during a visit to both destinations in August 2022.

Sights

Norwegian Aviation Museum – Bodø

The Norwegian Aviation Museum in Bodø is located on the northeastern corner of the airport, dominating this coastal town north of the Polar Circle. The airport was founded back in the 1920s, strongly potentiated by the Germans in WWII, and extensively used over the Cold War decades for mixed military and civil use. Today, it is mainly a commercial airport, with some residual military activity. However, the Air Station at Bodø shows evident traces of a military past – aircraft shelters, bunkers and large antenna arrays point the hilly panorama south of the runway.

The museum covers many aspects of the history of aeronautics in Norway. Both civil and military aviation are well represented, the respective collections being hosted in two adjoining large halls, merging into the central atrium – featuring a Northrop F-5 in the colors of the Royal Norwegian Air Force (RNoAF). This type has been the backbone of the RNoAF in the latter decades of the Cold War years.

Civil aviation hall

The proposed path in the civil aviation hall follows a chronological order, and starts with a display of memorabilia from the early aviation years and from the age of the adventurous polar explorations. The items on display include flags, historical pictures, personal belongings taken by explorers on polar exploration trips and many interesting explanatory panels.

Aircraft on display include rare early seaplanes, employed to establish transport services. These are put side by side with more modern aircraft of the company Widerøe, which today is responsible for most of the short-range high-frequency services linking the scattered settlements in the northern part of Norway – up to North Cape.

Nice advertisement posters are displayed to retrace the history of some classic airlines, including the all-private Braathens, once a major airline from Norway, and telling about the foundation of SAS – which incorporated also Braathens at the turn of the century – which stands for ‘Scandinavian Airlines System’. It is still today a big carrier linking Northern Europe and the world. These companies were among the world first massively flying polar routes, thanks to on-board instrumentation specifically made to tackle the navigation issues showing up when flying close to the poles.

A turning point in the history of Braathens has been the introduction of jets, in the form of the Fokker F.28, for which this airline has been a launch customer. An exemplar of the F.28 is partly preserved in the museum, allowing to check out the fully analog cockpit.

Helicopters, including one with a special pod hosting an entire berth for SAR operations, are also well represented. The Police is clearly using the latest models of rotary wing technology.

A rare aircraft on display is a British-made Britten-Norman Islander, once operating in the colors of the local company Norving. Very evocative pictures show the unusual scenarios often faced by airlines operating in near-polar regions!

Another peculiar mission covered by aircraft in Norway has been that of territory imaging and survey, including for archaeology in the search for ancient viking remains, typically hard to see from ground level. A Cessna 337 Skymaster push-pull originally tasked with this mission is on display. This type is pretty hard to see in Europe, but has enjoyed even a significant military career in the US (see this post).

A big bird on display is a beautiful original Junkers Ju-52 three-props seaplane. This is one of four originally in the fleet of the Norwegian flag carrier ‘Det Norske Luftfartselskap’, established in the 1930s, and operating with a mixed fleet of British, German and American models.

The cockpit of the Junkers has been put in a display case to be admired more easily.

Among the many other items on display in the civil aviation hall, you can find an original wind tunnel model of the Concorde, aircraft remains from an accident, and some unusual or one-off aircraft models.

Military aviation hall

The hall dedicated to military aviation starts again following the timeline of aviation history. The early-age manufacturers appearing in Norway when aircraft were still a totally new technological novelty are represented with dioramas of technical shops, scale models and historical pictures. Some aircraft dating to the pre-WWII years are also on display.

However, a major subject covered in the display is that of WWII. Norway was conquered by the invading German forces in a short and aggressive campaign in Spring 1940. Well planned from a strategic viewpoint, this operation included the capture of the airport of Oslo – the old field of Oslo-Fornebu – on the 9th of April, which was then used as a major base for landing transport aircraft, unloading military staff and material in the most populated area of the Country.

The landslide Third Reich invasion forced the government and the military chain of command to withdraw to Britain. An agreement was then settled to establish a military flight academy near Toronto, Ontario, to supply the Norwegian armed forces with new pilots, to carry out offensive operations from Britain.

The collection features many interesting items from WWII period. From a balcony you are offered a view of the collection, and a vantage view on the relic of a Luftwaffe Junkers Ju-88, transported to the museum after recovery.

The air operations in the invasion of Spring 1940 are documented with interesting scale models and dioramas, as well as much technical material retrieved from the days of German occupation. This includes cameras for photo reconnaissance, Third Reich military maps of the region, flags, aircraft engines, and many historical pictures.

From the same era, the cockpit of a Soviet Ilyushin Il-2 Sturmovik, documents of the air actions against the Third Reich occupants, and others concerning the history of ‘Little Norway’ – the Norwegian military training facilities in Canada – are also on display.

Aircraft displayed in this area include restored or partly reconstructed examples of a De Havilland Mosquito, a Supermarine Spitfire, as well as a Focke-Wulf FW190 and a Messerschmitt BF-109 on the German side.

All these birds together make for a really unusual and evocative sight today! Especially the German fighters are really rare to find, and their condition and presentation is really eye-catching.

Further aircraft from the time include a North American Harvard trainer, and a big Consolidated PBY Catalina seaplane used for patrol. The latter looks really massive hosted indoor, compared to smaller fighter aircraft!

Anti-aircraft guns and a pretty unusual radio emitter/transmission station, employed as beacons for helping instrumental navigation in the war years, are also part of this interesting display.

Next to the WWII area is the Cold War section of the display. Following the bad WWII experience with a policy of international neutrality, resulting in an invasion by a powerful enemy force, following the escalating divergence between the western Allies and the USSR, Norway opted for joining NATO as a founding member.

The alliance with the US and Britain, similar to other NATO Countries, meant a substantial supply of American and (at least in the beginning) British military supply. A North American F-86 Sabre and a Republic F-84 Thunderjet are two beautiful representatives from the early Cold War era. Similarly, a De Havilland Vampire is hanging from the ceiling.

A slightly more modern item is a Lockheed F-104 Starfighter. Not much employed in the US, it covered the interceptor role along the border with the Eastern Bloc in Norway, Federal Germany and Italy for many years.

Historical pictures tell – among many interesting subjects – about other aircraft, like the Lockheed T-33 Shooting Star, as well as the F-104 and the F-5 involved in interception and escort flights, shadowing Tupolev Tu-95, Antonov An-12 and other USSR machines flying over international waters or scraping the border of Scandinavian airspaces – quintessential Cold War memories!

Possibly a reason for Bodø having grown to further fame in the aviation community of Western Countries is the presence here of a real Lockheed U-2 spy plane. This aircraft can be found in Europe only at the Imperial War Museum in Duxford, Britain, and here. Actually, a curious fact about Bodø is that it was a designated destination or an alternate (emergency) airfield for the perilous overflights of the USSR, carried out with the Lockheed U-2, and later with the Mach 3+ Lockheed SR-71. Actually, the latter landed here in one occasion, whereas the ill-fated mission of Francis Gary Powers, downed by Soviet SAMs while en-route north of Kazakhstan from Peshawar, Pakistan, had Bodø as a destination (see this post for pictures of the relic in Moscow).

The U-2 is displayed so that it is possible to both appreciate its slim shape and large wing span, and also get near to its cockpit. However, its installation and lighting inside the hall – and the fact that it is black… – make it a rather difficult target for photographs. Next to the aircraft, historical pictures and schemes tell about the mission of Francis Gary Powers. Interesting tables for the interpretation of photo intelligence are also on display.

Still in the Cold War part of the museum, a very unusual and interesting section is centered on the facilities and technical gear for the detection and monitoring of airspace intrusion, for early warning and for alerting the air defenses of the National airspace.

This secretive and little publicized branch of the military kept its ears and eyes constantly pointed on the moves of the colossal Soviet neighbor, recording every single movement – look for the super-interesting registry of USSR aircraft movements! – and constantly updating the situation, in order to be ready to counter a sudden ‘turn for the worst’, in case of an actual attack.

Interestingly, much of the electronics here is US made, as can be seen looking at the product tags.

The arsenal that could be employed to counter an air attack included the Nike-Ajax and later Nike-Hercules surface to air missiles, deployed along the border with the Eastern Bloc also in Denmark, Germany and Italy (see here and here).

Just to complete this incredible Cold War exhibition, an interesting and pretty unique air-dropped WE-177 nuclear bomb case is on display!

More modern addition to the aircraft collection include a General Dynamics F-16 Fighting Falcon and some helicopters.

A latter interesting part of the military exhibition showcases an array of aircraft-mounted cannons from various ages, showing their precision and their effect on the same target. You can appreciate the effects of the technical evolution of these weapons.

Examples of air-launched missiles and sonobuoys, and a fine array of flight suits showing the evolution of their design, conclude this exceptional museum.

As a plus, the old control tower of the military air station has been turned into a panorama point, where you can watch air operation on the actual airport, and also listen to air traffic frequencies!

The gate guardians include a Bell helicopter and an old glorious Hawker Hurricane from WWII.

Visiting

The museum is located at Bodø airport, and can be spotted pretty easily when entering the town. Bodø can be included – or considered as a starting point – in many tours of Northern Norway. The museum offers a large and convenient parking. It can be toured in not less than 2 hours for aviation-minded people. The website is here.

Norwegian Armed Forces Aircraft Collection – Oslo-Gardermoen

Coherently with its name, this wonderful collection is focused on military aviation in Norway. Most aircraft having served in the RNoAF at some point in history are represented, as well as some from WWII – not only from the Allied side, but most notably some rare exemplars from the Third Reich.

A great feature of this museum is also the architecture of the display. Put in a U-shaped building to the southwest of Oslo-Gardermoen airport, the aircraft are in most cases sufficiently far from one another to allow moving around freely, getting an unobstructed view from different angles. Furthermore, the natural lighting from the top windows is ideal for pictures (similar to the solution adopted in the Estonian Aviation Museum, see here).

Late 20th century

The display starts with the Northrop F-5, which is represented by three exemplars, interspersed with a single example of a General Dynamics F-16 Fighting Falcon – currently in use with the RNoAF, to be replaced by the Lockheed Martin F-35 Lightning II. The Freedom Fighter has been the backbone of the RNoAF for the latter years of the Cold War, being flanked and substituted by the Fighting Falcon, and now by the Lightning II.

The aircraft on display are two F-5 Freedom Fighter, i.e. the light fighter version – one in a distinctive tiger painting – and one RF-5 Tigereye, which has been developed from the original design into a capable photo reconnaissance aircraft.

Walking beneath the F-5 reveals many details, for instance the landing gear mechanism, the missile pylons and anchoring system, and JATO bottles for reducing the take-off distance.

A J85 jet engine – there were two for each F-5 – is on display, with the afterburner pipe mounted past the turbine exhaust. A choice of missiles and pods can be seen close to the ‘tiger painted’ exemplar. The latter can be boarded. The fully analog cockpit shows much standard instrumentation for flight control, navigation and engine management, but also an armament panel with weapons selection and activation switches. Also interesting are the parachute deployment lever, for the arresting parachute, or the underwing load jettison system.

The RF-4 reconnaissance aircraft features a nose camera, with a prominent lens which can be easily checked out. Similarly, the hatch of the port 20-mm cannon has been left open, showing the cannon body, barrel and the very neat ammo supply system.

Next to these aircraft are a Lockheed F-104 Starfighter in a two-seats trainer configuration, and the front section of another exemplar with the original cockpit, which can be boarded. The J79 engine of the Starfighter, apparently originally from Canada judging from the Orenda labels on some components, has been taken out of the fuselage and can be appreciated in all its length (with the afterburner pipe to the back).

The cockpit of the Starfighter is cramped, with little legroom and a very limited front visibility. It is fully analog, similar to the F-5.

In a corner of the hall, an original simulator – apparently for an F-16 – has found a new collocation, possibly from a military aviation academy.

Early Cold War

The next part of the display offers the sight of a full array of fascinating, well-preserved aircraft from the early Cold War period. The first is a North American F-86 Sabre, with an attractive golden front intake decoration. Walking around and looking closely, many particular features can be spotted, including the leading edge slats. A ‘used’ Martin Baker ejection seat shows the little damage resulting from actual employment in case of emergency.

Next is an improved version of the Sabre (F-86K), which features a very different intake, such to accommodate in the bulbous nose a powerful radar antenna. The latter could work in conjunction with a computer, and offered a substantial help in increasing the offensive capability of this fighter, which could also be operated in all weather conditions.

A nice gem of the collection is an original portable cabinet for testing the General Electric J47 engine. This cabinet looks like a suitcase, but it could be positioned standing on its legs, linked with connectors to the on-board systems, and could show the working condition of the engine in a mounted configuration. The monitoring instrumentation is fully analog. It would make for a great item for collectors of Cold War technical gear!

Then follows an Republic F-84 Thunderjet early jet fighter, with its neat lines, wing tip tanks, and an under-fuselage spoiler in a deflected position.

Nearby, the rather different – despite the similar code – Republic RF-84F Thunderflash photo reconnaissance aircraft prominently displays its big-diameter optics in the nose.

The really elegant design of a Lockheed T-33 can be appreciated next. The air intakes are really works of art, and the bare metal color just adds to the vintage line of this early design.

Similarly graceful is the iconic De Havilland Vampire, the only British addition to this US-dominated aircraft display from the Cold War era. With its distinctive twin-boom tail, the typical De Havilland vertical fins dating back to the pre-WWII propeller-driven examples, the shrouded jet engine totally disappearing in the body of the aircraft, with small, fenced intakes on the leading edges of the wing, this aircraft looks like a really good balance between engineering-driven design choices and pure elegance.

WWII aircraft

A central section of the exhibition is centered on WWII-era aircraft, starting with two Supermarine Spitfire, one hanging from the ceiling, and one sitting on its wheels, in a greenish color and RNoAF emblems.

What follows is a pretty unique US-made aircraft, a Northrop N-3PB seaplane, ordered as a sea patrolling aircraft by Norway, but not reaching Scandinavia in time before the German invasion. It was then employed as a sea patrol from Iceland by the Norwegian forces in exile. Possibly looking not so conspicuous in pictures, it is a rather massive bird. It shows an interesting floatplane design, where floats are anchored to the wings through aerodynamically profiled struts, so as to reduce drag as much as possible.

Walking around it, you can notice the relatively light weaponry hanging from the fuselage bottom, the down-firing back cannon for defense, and the detachable wheels to pull the aircraft ashore.

Then a very rare bird follows – a German Heinkel He-111 bomber from WWII! Restored in a mint-looking condition, this aircraft makes for a unique sight in the panorama of aviation collections.

This iconic aircraft from the Third Reich, much known to aviation-minded people especially in connection with the early landslide campaigns of the Third Reich in Europe and for the Battle of Britain, can be examined from very close and beneath, unveiling some interesting peculiar features. For example, the bomb bay features vertical square-section separated ‘blisters’, a totally different solution with respect to larger US bombers from the age.

The underbelly shooting pod allowed the cannon operator to ‘rest’ in a laid down position. The front cannon is clearly asymmetrically placed with respect to the aircraft centerline, following a side curvature of the nose cone such to increase pilot’s visibility.

Close by is another incredibly well-preserved addition from the Third Reich’s Luftwaffe, a Junkers Ju-52 transport in fashionable military colors.

The Ju-52 and He-111 were the main characters involved in the blitzkrieg attack to Oslo-Fornebu, the now bygone airport of central Oslo, which was the stage of a massive air-launched German attack in April 1940, a substantial contribution and a prelude to the complete invasion of Norway. Both aircraft are surrounded by a set of accessories from the time, including searchlights, fuel tanks, spare parts, anti-aircraft guns and even service trolleys with skis to be used on snowy aprons! The ensemble is really quite a sight.

From roughly the same age is also a perfectly preserved Douglas C-47 Skytrain – a true war veteran! Preserved in the colors of the RNoAF, it was originally incorporated in the USAAF and employed in action in Europe since mid-1944. It flew during the Berlin Airlift, operating in and out West Berlin transporting goods during Stalin’s blockade of the town in 1948-49 (see this chapter). It later joined the RNoAF and was employed for radar tuning and for transport until the mid-1970s.

The color scheme of the RNoAF looks great on this C-47, and the presentation among some airport service vehicles from the time adds to the display.

Further recent aircraft

Approaching the extremity of the U-shaped building, you can find a De Havilland Twin Otter with skis, some classic helicopters, some aircraft undergoing restoration – including substantial remains of a Junkers Ju-88 bomber from the Third Reich! – and a massive Lockheed C-130 Hercules.

The latter is possibly the aircraft in the collection having been retired most recently. It has been deprived of its vertical fin, which simply couldn’t fit inside the building, but the rest is almost complete. The engine pods are opened, so that you can see inside. An array of JATO bottles to enhance take-off performance has been anchored to the side of the fuselage.

The aircraft is on display with the back and side doors opened, so that boarding its preserved interior and cockpit is indeed possible.

Inside the cockpit, chance is you meet a living legend, the flight engineer of the RNoAF Mons Nygård, who will explain you the features and operations of his aircraft! The man joined the Armed Forces in the late 1950s until the 1990s, with a military career spanning a big part of the Cold War. He flew extensively the Hercules, as well as other aircraft including the Lockheed P-3 Orion, logging a staggering  more-than-17’000 hours in flight!

We could interview him about his career, which unfolded several nice anecdotes and memories from the Cold War years, and a real passion for his super-reliable aircraft and for his job. It’s no wonder the Hercules, being designed in the 1950s, is still in service with many Armed Forces of the world.

Anti-aircraft defense system

Finally, the exhibition includes Nike-Ajax and Nike-Hercules anti-aircraft missiles (SAM). Installed in batteries against an attack from the USSR also in Norway (see for instance this preserved battery in Italy, this in Denmark, or this ghost one in former Federal Germany), these nuclear-capable massive missiles were in service typically between the 1950s and the early 1980s, becoming by then obsolete.

Of great interest for technically-minded people are some of the inside components of these missiles, including components of the guidance system and some electronics, which can be seen in display cases, as well as technical vehicles for launch control, radar operation etc.

Other lighter anti-aircraft weapons from the Cold War era are displayed nearby, thus covering also this interesting subject in good detail.

Balcony

The visit may be concluded with a walk along the inside balcony, from which a good view of all the aircraft just mentioned is obtained.

On the same balcony, you can find also many trainers once used for teaching young pilots the basics of flight. Some are classic models belonging to the era of Little Norway and WWII, when training for freshly recruited pilots was carried out in Ontario, Canada.

The gate guardians for this beautiful collection are an F-5 and an F-104, the latter in the greenish colorway seen also in the collection in Bodø.

Visiting

This fantastic collection can be found in the southwestern corner of the premises of Oslo-Gardermoen airport, the main airport serving the Norwegian capital city.

The museum is administrated by the Armed Forces.

Visiting for the aircraft enthusiast may be very rewarding and may take more than 2 hours, since the exceptional state of preservation of the artifacts and the many details you can explore through a walk around very close to the aircraft invite to spend time inside. You have also chance to speak with former military crew, which adds much to the experience. Very good photo opportunities for an indoor collection.

Large free parking ahead of the entrance, with picnic facilities. Nice model shop by the ticket office.

The museum is normally open on weekends, but further visits may be scheduled out of these opening slot. Please check the info on their website here.

The Atlantic Wall in Denmark

A pleasant country in northern Europe, Denmark is geographically surrounded by the North and Baltic seas, and shares its only land border with Germany. In the late 1930s, this meant having a very dangerous dictatorship as the only neighbor, and no possible direct help coming by land from other allies. Without natural defenses against and attack from the south, the Kingdom of Denmark was militarily occupied basically in one day, on April 9th, 1940. This happened through a joint operation carried out by the land, air and naval forces of Nazi Germany.

A quick historical overview

The interest of Germany in controlling Danish territory was mainly strategic. It served as a springboard to attack Norway further north. The latter was in itself more interesting to the economy of the Third Reich, as it was rich of natural resources, including raw materials not available in Germany. These were so needed by the Führer, who was dreaming of making Germany independent from international supply trade.

Furthermore, controlling both Denmark and Norway meant control over the eastern coast of the North Sea, and a chance to control the only access to the Baltic Sea. The USSR was not a declared enemy before 1941, but withdrawing from the mutual cooperation pact with Stalin – signed in a hurry just days before the invasion of Poland in September 1939 – at some point, and openly attacking Russia, had been in the mind of the Führer since he first put on paper his worrying geopolitical thoughts. By controlling the Baltic, Hitler could control sea trade to non-freezing ports of the USSR, which in 1940 had already taken over Estonia, Latvia and Lithuania in agreement with Germany.

As a matter of fact, the conquer of Norway was not without significant losses for Germany. This was also the result of Britain starting to militarily oppose Germany. The two countries had been already at war since September 1939, but without any serious confrontation having taken place for months.

Since then, the British – and later also the American – threat from the west had to be faced through the fortification of the western coast of the Third Reich, which by the end of the summer of 1940 extended roughly from the Pyrenees in southern France to Kirkenes in northern Norway. This highly visionary task was taken up very seriously by the German military-economic machine, and produced the ‘Atlantikwall’ – which translates pretty obviously into the ‘Atlantic Wall’. This long defensive line had to be built all along the coast, and was mainly based on a catalog of standardized reinforced concrete constructions, to be reproduced in great numbers. Construction was coordinated by the main contractor, the German ‘Organization Todt’, which made extensive use of subcontracted local companies in the various occupied states where construction had to take place.

Despite the majority of the elements in the line were reinforced barracks for troops watching the coastline, ammo and supply storages, command and communication bunkers, canteens, and other service buildings, there were of course also a number of heavier constructions. These included coastal gun batteries, to counter attacking ships, lighter gun batteries, to stop troops attempting a beach landing, aiming stations, to adjust the line of fire of gun batteries, anti-aircraft guns to defend the line from air attacks, and some technical buildings serving as bases for advanced radar systems. The latter were among the most useful and widespread items along the line, as German technology developed fast during the war, to produce powerful detection systems against air and sea menaces.

Needless to remember, similar to many pharaonic works conceived by the Führer and his entourage, the Atlantic Wall was never completed, and it failed to spare the Third Reich from total annihilation. The once-modern military installations along the western coast of Europe soon became obsolete, as war changed face at a quick pace following WWII, with new weapons and techniques. Furthermore, the front line of the new Cold War shifted geographically to the middle of Europe. A tangible sign of enemy occupation, the massive bunkers of the Atlantic Wall met different destinies depending on the country. However, albeit only rarely preserved, thanks to their bulkiness and sturdy make, they are in most cases still visible.

About this post

Being the first land along the western coast to fall under German control, work on the Atlantic Wall started in Denmark earlier than anywhere else. Today extensive traces of the line are still pointing the shores of the North Sea.

A few focal points are preserved as first-class museums. These include the strongholds of Hirtsthals and the huge battery at Hanstholm, in Northern Jutland. The latter had been designed around a cluster of four monster coastal guns, to the aim of controlling the passage through the Skagerrak channel, providing access to the Baltic Sea. A twin battery – Vara – was built to the north of the strait in Norway.

Closer to the German border, the area of Blavand – featuring also the famous ‘Tirpitz battery’ in its arsenal – is another example of a partly preserved portion of the line. Bangsbo fort in Frederikshaven has been partly refurbished and opened as a museum, after being used by the Danish military for a while. There you can find one of the few remaining examples of an Atlantic Wall installation with its original guns still in place.

Smaller strongholds, opened as smaller scale museums or left to more adventurous explorers, often feature unique special constructions, which justify a detour at least for more committed war historians. These include the Skagen battery, the disguised bunkers in Thyboron, and the complicated Stauning battery, built on two opposite coasts of a closed firth.

All these sites – and a few more – are covered in this post, which is based on photographs taken in August 2019. Denmark is officially protecting the installations of the Atlantic Wall as historical buildings – unlike France, for instance – so visiting even abandoned sites maybe rewarding, especially if they are out of the mainstream touristic routes. Unfortunately, many bunkers now closer to crowded touristic areas have been damaged by vandals.

Blavand – Shore Battery & Military Area

Located about 50 miles north of the German border along the coast of the North Sea, the small town of Blavand sits on a promontory protruding towards the sea, and protecting the access to the port town of Esbjerg – still today a major commercial port of Denmark.

The area of Blavand saw the construction of an incredible number of Atlantic Wall elements, which grew up in more instances during the war years.

Close by the parking ahead of the lighthouse on the very tip of the promontory, you can find trailheads leading to the southern and western shores of the promontory.

The southern shore makes for a typical North Sea landscape – an endless sand beach. What makes it different from others is the number of light bunkers placed along the shoreline. Despite little imposing, this model – type ‘F’ – was purpose built for the wide shores of Denmark in 1944, in view of a potential enemy beach landing. These firing positions were armed with machine guns, and placed at pre-determined intervals – about 1’500 ft – matching their accuracy range.

Many bunkers are slowly sinking in the sand, and only small parts of them can be seen emerging from the ground.

Others have been turned into strange sculptures, adding a horse head and tail.

Under favorable tide conditions, you may enter some of the bunkers. There you can appreciate their simple structure, with a defensive embrasure by the entrance (looking towards the coast) and loopholes to the sides of the firing chamber.

On the beach close to the lighthouse you can find a very big bunker with a wide hollow cave on the inland side, which used to support a searchlight.

Along the western shore you can find more massive bunkers. These include four former coastal gun batteries. These heavier constructions have assumed strange attitudes, after sinking in the sand somewhat irregularly over the years.

Looking towards the inland from the beach, you can spot an aiming/fire control positions, with a distinctive bulbous roof and a long curved slot on the facade.

Your walk along the northern shore may be interrupted by safety warnings concerning mine threat. As a complement to the defensive potential of the Atlantic Wall, extensive minefields were set up on most of the Danish beaches. This turned into a big issue soon after WWII, when an extensive demining action had to be carried out.

Furthermore, part of the Blavand promontory is occupied by a military firing range. When training exercises are taking place, special warning lights are lit and flags are raised, to delimit the territory where you should not venture.

In the dunes slightly inland from the shoreline, it is possible to find another big number of bunkers. They are not always visible from the distance, and entrance is in most cases from one side only – the only side emerging from the sand.

A very distinctive item is the colossal platform for a ‘Mammut’ type long-range anti-aircraft radar. This used to be operated by the Luftwaffe, whereas other bunkers in Blavand – like elsewhere along the Atlantic Wall – used to be run by other branches of the Germany military.

The base for the radar is in itself a rather complex bunker, with several cavities and extensive piping, once needed for power cables feeding the antenna, as well as other wiring.

Close by, a smaller radar base bunker used to be operated by the German Navy. Also here, holes and passages for cables can be found in the walls and roof.

It is noteworthy how many bunkers feature traces of original decorations, like painted walls, fake wallpaper, frescoes and small frieze lines. This is typical to many other installations of the Atlantic Wall.

Metal hardware can be found in the form of a bulky aiming turret emerging from a bunker.

In another instance, a mortar mouth pops out from the ground.

The underground bunker underneath the latter can be explored with some difficulty – there are also quite annoying bats inside -, but it reveals an aiming wheel with original markings in a reinforced concrete dome!

An interesting sight nearby the lighthouse is the tower once supporting a ‘See Riese’ radar. The protruding arms once sustained a wooden platform for military operators.

Getting there and moving around

The area of Blavand is rather extensive and rich of diverse installations, so notwithstanding the general bad shape of most of the bunkers, visiting may easily take 3-4 hours for a committed tourist, getting inside most of the items. A good starting point is the free parking by the lighthouse, provided you come early especially in summer, cause it tends to get more and more crowded along the day.

Blavand – ‘Tirpitz’ Coastal Guns

Despite at least some of the bunkers on the shores of Blavand being in a relatively good shape, there is a part of the Atlantic Wall which is officially preserved as a museum. This is one of the two unfinished bunkers intended to support a set of massive 38 cm coastal guns.

These guns – four, two for each bunker – were originally intended to be put on board battleship Gneisenau. The latter got damaged in port, and the guns were diverted to coastal use. The decision to build the Tirpitz battery to protect the port of Esbjerg came relatively late during the war, in 1944. As a result, construction of the battery supporting structures was not completed when the war ended, and the four never installed guns were scrapped – except one, which can be admired in Hanstholm (see below).

The name ‘Tirpitz’ attributed to this battery is of uncertain origin, and sometimes this installation is also referred to as ‘Vogelnest’.

The museum has been built only in the southernmost bunker. The installation is very modern (and crowded), and it has been designed as a thematic museum in five sections. Two of the most interesting are about the Atlantic Wall and its impact on local life, and on the extensive mining and demining operations on the shores of Denmark.

Other sections are related to amber trade and local seamen activities.

Finally, you can get access to the base of the gun turret. Photographs are bad here, due to very poor lighting and limitations on camera use.

You can see a central round dome, surrounded by an external corridor. Traces of a post-war explosion can be noticed looking at the metal part of the construction.

Outside of the museum you can find a cannon cut in pieces, plus rigs used for construction. The bulky concrete arms protruding from the roof were meant to support the crane for mounting the cannons.

With a five minutes walk from this bunker, you can get to the northern battery. This is not preserved, and the entrances have been bricked up. Yet you may better appreciate the size of the bunker from this exemplar than from the one turned into a museum.

Getting there and moving around

The museum is located east of Oksby along Tane Hedevey, a local road connecting Blavand to Esbjerg. There are signs along the road, and a large parking ahead of the entrance. The museum is very modern, and may turn very crowded in summer. Website with full information here. You can visit on your own with an audio-guide. The visit to the military-related sections may take about 1 hour.

Adding a walk to the northern battery will take further 20 minutes at most, as there is no chance to step in.

Stauning Battery

Construction of this battery started in the second half of 1944, and consequently it was only partially completed before the end of the war. The geography of the Stauning battery is rather peculiar. The intended design was based on four coastal guns to be placed on the inland side of the Ringkobing firth – basically a lake with a channel-like small mouth connecting it to the sea. On the other coast of the firth, i.e. very close to the North Sea in Hvide Sande, the aiming station for the battery was finally built.

In the event, only one of the reinforced concrete gun positions reached completion, whereas the other three cannons were kept on basic, not reinforced aprons. The gun bunker is the only exemplar of this model built along the Atlantic Wall, and was designed around a 19,4 cm gun manufactured in France.

Located far from the shore in a secluded area of the countryside, this battery is in a relatively good shape, and thanks to the hard soil its position has not drifted since it was installed. You can even walk on top.

More elements are scattered in the bushes and over the private pasture nearby. Among them, a firing position presumably for anti-aircraft or light field guns, and corresponding ammo storages.

There is also a reinforced concrete barrack or command post. This can be toured inside, revealing some metal piping still in place.

Traces of gun concrete platforms – likely gun firing positions – blown up after the war can be seen, similar to many smaller cubic buildings of uncertain purpose.

A couple of unattractive half-interred ‘living bunker’ can be found too, another design present only in Denmark – the type was named ‘Falkenhorst III’. Inside, traces of original wall paintings can be easily spotted.

There is actually a fire direction post of some sort in this part of the battery too. This is a square-based concrete booth, with an adjoining living bunker.

The aiming position in Hvide Sande is rather easy to find, on top of a mound close to the city center. There are actually two concrete accesses on the eastern side of the hill. The one closer to the top gives access to the metal dome you can spot on top of the mound.

Climbing up to the dome is possible along a rusty ladder, going through a narrow vertical passage. Once there you can see the mounting of a telescope for measurements. There are side slots looking outside, and an original marked wheel to provide measurements. You can also spot small foldable wooden tables (or perhaps jump-seats).

Downstairs, there are a few panels explaining the history of the battery.

The second concrete entrance gives access to a ‘living bunker’ for the troops, with explanatory panels on the history of the place.

Getting there and moving around

The inland part of the Stauning battery with the gun station is located close to Stauningvej 55. You may park your car not far north from this address, on a wide lot close to the entrance of a local residential area. Most notably, this battery is about .5 miles from the beautiful Danish Museum of Flight (see this post). Exploring the battery may take 1-1.5 hours, as the place is totally wild and inconvenient to visit.

The Hvide Sande point is on the northern rim of the channel linking the firth to the North Sea. You can see the mound close by a major round about, where road 181 meets Troldbjergsvej. There are several parking options nearby. The place is technically not abandoned, but there was no ticket/staff, and it was totally dark when I visited. You would better take a small torch with you.

Sondervig

Just as an example of how extensive the construction of the Atlantic Wall was in Denmark, you may have a look to the beach in Sondervig, where people spending the day by the sea are accustomed to the view of the monstrous German bunkers pointing the shore.

Getting there and moving around

You may find a parking spot in Sondervig and access this famous touristic beach by foot.

Thyboron

The coastal battery at Thyboron has a unique place in the panorama of Atlantic Wall buildings. Here a sort of sample list of possible deceptive techniques were tested on otherwise normal bunkers. The usual constructions pointing the shore have a strange appearance here, thanks to the imaginative talent of a Danish architect – who turned out to be a spy working for the Allies.

At least two gun batteries bear a special roof, resembling that of a house. Also thanks to erosion, they now have even odder shapes, resembling some Star Wars spaceship.

An observation bunker bears a tiled roof. Surprisingly, an apparently original fragment of telegraph wire can be found inside.

Given the position of the bunkers – lying isolated on a deserted beach – it’s pretty difficult to suppose this kind of deception was ever effective…

There are also some more straightforward constructions around, some of them in a relatively good shape. The cusped lintels above most doors and openings are typical to elements of the Atlantic Wall in northern countries, and are made for protecting the passages against snow and icing rain.

Just inland from the ‘sample list’, you can find a large underground bunker, somewhat difficult to access – it is sinking in the sand. Conspicuous traces of original wall painting and even writings in German can be found on the walls.

The message in German is a warning message, telling to stay away of the walls in case of bombardment. This warning sign is rather ubiquitous in Danish bunkers.

Close to the the city center – and actually a part of the Coastal Center, a museum for children dedicated to the life along the western coast of Jutland – it is possible to find another bunker deceived as a wooden house! This deception technique is far more convincing than those on the shore…

Getting there and moving around

To visit the bunkers on the shore you can reach a convenient public parking at the southern end of Vesterhavsgade, southern Thyboron. Visiting these bunkers may take about 45 minutes for a committed tourist. To get to the Coastal Center you may follow the signs and park at your convenience ahead of the building. The deceived bunker can be seen from the outside of the museum, so getting the ticket is not needed if you are not interested in the rest of the installation.

Extra feature – Sea War Museum, Thyboron

Thyboron has a prominent place in WWI history, being the Danish village closest to the area of the Battle of Jutland, one of the very few naval battles of that war, and one of the top-ranking in history for the number of vessels and tonnage involved, and for the casualties – almost 9’000 seamen were killed.

The battle was fought between two major formations of the the German Kaiser on one side and the King of England on the other. Started almost by chance, as the two opposing factions appeared on the same sector unaware of each other, the fighting was so intense that cannon fire was heard along the shores of Thyboron for many hours. The battle ended with a tactical defeat on the British side, but the Kriegsmarine of the Kaiser avoided any other serious clashes with the British for the rest of the war – in this sense, this was a British strategic victory.

Today, a monument dedicated to those who perished in the Battle of Jutland occupies a wide area over a promontory in northern Thyboron, close by the Coastal Center (see above).

A nice museum dedicated to sea war has been put in place nearby. On the exterior you can find old mines, torpedoes and even parts of relics taken from the bottom of the sea.

Inside you can find many unique artifacts, including cannons, insignia, and everyday items from ships taking parts to the Battle of Jutland.

Also unique are parts of early submarines dating from WWI, recovered from the sea thanks to novel investigation and capture technologies.

The museum is at large dedicated to naval battles and ventures of WWI. A section is dedicated to the most modern sea archaeology techniques.

Outside of the museum, you may spot a few Atlantic Wall bunkers as well, likely converted into more modern military installations in a post-WWII period. They are apparently run as museums, but they were closed when I passed by.

Getting there and moving around

The Sea War Museum is located very close to the Coastal Center in central Thyboron. Dedicated free parking right ahead of the entrance. Visiting may take about 1.5-2 hours for more committed subjects, despite the small size. The museum is stacked with extremely interesting details, the exhibition is rich and well made. Really an interesting detour for anybody interested in sea war. Website here.

Agger

Agger is located north of the Thyboron Channel, and can be reached with a five minutes ferry ride from nearby Thyboron. The long, windy, wild and distressing beaches south of the village of Agger are not really welcoming, nor easy to visit. Yet here you can find some unique and imposing elements of the Atlantic Wall.

These include a firing control bunker of the Navy. A feature often found also elsewhere, you can see some of the concrete bunkers are made of joined blocks. Light can be seen coming from the thin slots between the blocks in some occasions.

Another special construction here is the support tower for a ‘Seetakt’ radar. The tall concrete tower is assembled together with a bulkier concrete base.

The assembly has slipped to the shoreline, and today it can be neared only in favorable tide conditions. Furthermore, it is sitting in a banked attitude, making it looking really derelict.

Thanks also to a rather bad weather, these elements of the Atlantic Wall looked really eerie when I visited!

Getting there and moving around

The Agger site is wild and not signaled. The area is part of a national preserve, and part of the endless beach is a stage for kites, surfing activities and other beach sports. There is an official parking at the western end of Lange Mole Vej, less than five minutes by car from the ferry terminal to Thyboron. From there you should go to the beach and walk north for about 15 minutes to get to the tower, the highlight of the show.

You may spot it from the distance. I could not get in the tower due to unfavorable tide conditions, but visiting inside may not take much time, for the expected condition is not good, with little left to see.

Hanstholm

The Hanstholm battery is one of the most developed of the entire Atlantic Wall. As pointed out in the introduction, together with the sister site ‘Vara’ in Norway – about 80 miles north – this battery was centered on four massive 38 cm cannons, installed to obstruct surface passage through the Skagerrak, and de facto controlling the access to the Baltic Sea.

An initial battery based on less powerful 17 cm coastal guns was put in place as soon as 1940. The gigantic 38 cm guns arrived only later and were tested, but never used in action. The metal parts of the firing stations, including the turrets and guns, were eventually scrapped in the early 1950s. Over the years, this huge installation, with more than 300 bunkers fell largely into private hands, and today many former storage bunkers are used as warehouses for machinery and goods by local owners.

Nonetheless, battery Nr.3 has been turned into a modern museum, after being largely refurbished to its original splendor. As such, it is a one-of-a-kind museum, with thousands of visitors per year. Two more turrets and a number of bunkers are left to explorers. While they are not actively maintained, they are still in a rather good shape, and responsible exploration is even supported with some indications.

The area of the Hanstholm is almost 4 square miles. In order not to get disoriented, a good starting point is the museum in and around turret Nr.3. There you are greeted by a pretty unique 38 cm cannon! This is actually from the Tirpitz battery (see above), but it is exactly the same item once installed in Hanstholm. The size is really remarkable, especially when compared to more modest and usual 15 cm coastal guns, on display.

The modern museum offers a quick recap of the history of the place, with memorabilia including everyday items, letters, maps and original weapons.

Once you are done with that, you can get access to the underground part, where you first meet the ammo storage rooms, on the side of a long corridor aligned along a narrow gauge railway track. This was used to connect the firing stations – i.e. the four bunkers with the guns – to larger ammo storages scattered around the are of the fort.

There are two major adjoining rooms along the corridor, each dedicated to a different part of the cartridge. The piercing part – the ‘bullet’ – and the exploding fuse were kept separated from each other. This is similar to naval guns, and typical to larger calibers. The complicated railings hanging from the roof were made to allow moving the parts of the cartridge by means of movable cranes.

In action, the bullets and fuses were loaded on a slide, and from there on trolleys which would enter the turret from below. Today, as the turret is not there any more, the trolleys are in an open air corridor, apparently without any sense. It is noteworthy that the inscriptions and frescoes are all original, albeit refurbished.

The structure of the firing station and of the Hanstholm fort can be better appreciated from the drawings and models below.

A second part of the firing station is the bunker for the complement of men needed to operate this complicated cannon. The place was permanently watched, with shifts spending the night in underground quarters. Those pertaining to firing station Nr.3 have been refurbished, and provide a vivid impression of the original appearance. There are sleeping and living quarters, as well as large, military style showers and toilets.

There is also a complete power station, with two Diesel generators, a mechanics shop, water tanks and more.

Out of the Nr.3 firing station you are encouraged to tour at least part of the site along a series of prescribed trails. Among the items you meet on this tour is one of the ammo storages. It is not dissimilar from the ammo storage part of the firing station. The ammo parts were loaded on a railway car passing through, and from there moved towards the gun turret.

There are also many smaller storage and service bunkers, some bearing interesting original inscriptions inside.

The Hanstholm fort was defended by field cannons and anti-aircraft guns. Emplacements for the latter can be spotted around in more instances.

Another suggested part of the visit is firing station Nr.4, which is not really preserved, but is not in a generally bad shape either. You can get in only if you have a torchlight. Visiting may offer something very similar to Nr.3, except everything is more derelict – but for this reason, may be more authentic.

In the living part, you can find inscriptions in German and traces of the original wall paint. With a general knowledge of the plan from the visit to Nr.3, you may easily recognize the corresponding rooms – power station, toilets, living rooms, etc.

To get to the ammo storage part, you can walk along the round corridor outside. No trolleys left here, differently from Nr.3.

Inside the ammo storage rooms, you notice that the inscriptions have been largely canceled for some reason, but the slides as well as the frescoes above them are still there.

Still part of the suggested itinerary, you can find a control station, in a rather bad shape, and more interestingly a very peculiar building, located on top of a cliff.

This was a fire direction station. Due to the high-tech nature of the Hanstholm battery, fire direction worked on what can be considered archaic computers! The building has many floors. There is provision for a permanent team of technicians, hosted in living and sleeping quarters downstairs.

The top floors used to host the computing machines, which were fed by measurements from instruments mounted in metal domes, facing on the roof of the building. The room for the computing machines is rather dark, and due to the black walls it is difficult to see anything even with a torch.

The Hanstholm site offers several ancillary bunkers open to the public. Among them, one for a generator, supplying the whole fort in case of a grid failure.

Another bunker is an ammo storage, with a big concrete arch outside, for a moving crane operating above railway cars. Narrow gauge railway tracks can be seen still today in this part.

The pivot in the middle of firing station Nr.2 has been interred after the war, but the living/sleeping quarters for the troops and the ammo storage parts can be visited, albeit they are not connected any more by a direct passage.

A visit to this firing station is very interesting, for writings are in a generally better shape than in Nr.4, even though this too has not been refurbished.

In the ammo storage part, writings are especially abundant. You can see also traces of the original telephone wiring.

The last firing station, Nr.1, is not accessible, even though not interred.

As said, there are many other bunkers an remains around, which are typically not accessible, especially the farther you go from the museum. They are now largely on private land and used for something else.

Getting there and moving around

The Hanstholm strongpoint is a must for everyone interested in the Atlantic Wall! The museum is modern, completely accessible, with a convenient parking and all usual facilities. Website here.

The refurbished part is basically only firing station Nr.3, but many other bunkers, like the fire control center, as well as firing stations Nr.2 and 4 are open for explorers, and they have not been spoiled by vandals. You need to go with a torchlight and proper clothing, but the visit may be very rewarding.

Many more bunkers around are closed to the public, as they are now private property and used for other purposes.

Due to the enormous size of the area, visiting may easily turn into a full-day or even multi-days business for an enthusiast. For the general public, a visit to the museum and one of the trails may take a 2-3 hours depending on the level of interest.

Hirtshals

Similar to Hanstholm (see above), the area of Hirtshals was soon selected by the Wehrmacht for a coastal fortification, thanks to its strategic position overlooking the mouth of the Skagerrak strait.

The first four 105 mm field guns were positioned here as soon as summer 1941. They occupied open-air concrete aprons, which still today bear trace of the original camouflage paint and deceptive net.

A peculiarity of this fort is its extensive network of trenches, which connect all the battle stations to the living quarters for the troops and the service buildings, like the canteen-bunker and the hospital-bunker.

On top of the steep cliff dropping to sea level, you can find the bunkers for the guns. These were moved from the open aprons in 1944, into purpose built reinforced concrete firing positions. A special feature here is the steep flight of stair giving access to the gun area from behind. This construction was made necessary by the particular morphology and rock type of the cliff.

You can spot significant traces of the original camo paint, and the letters ‘St’ on many walls, meaning ‘Ständig’, i.e. resistant in German. These letters were used to mark those buildings capable of sustaining shelling and bombing raids.

A bulbous roof allows to easily recognize the fire direction station.

A more rare item in Hirtshals is the base for the ‘See Riese’ radar. This is a hexagonal concrete hollow platform. The bunker underneath it would serve to host a Diesel power generator.

Back from the coastline, you may enjoy a long exploration of the trenches and of the many restored bunkers. Many bear original markings and paintings.

In some rare cases, you can also find original decorative paintings, likely made by the soldiers stationed in the bunkers.

Restored bunkers include a ‘living bunker’, but many other installations are in good conditions, like interred shelters, ammo storages, etc. Traces of cables, armored doors – some of them with glass lights – and telephone wires can be found in many bunkers.

Furthermore, in Hirtshals you have the chance to get a bird’s eye view of the fort, by climbing on top of the local lighthouse!

Getting there and moving around

The Hirtshals site is an open-air museum. There are technically opening times, but the area is not fenced, so if you are looking for a visit to the exteriors, you can walk around freely at any time. The museum has a website here, and guided visits are offered in many occasions. Many bunkers were closed when I visited, and they might be visible only with a guide. Some other bunkers are open and lighted, whereas the majority are basically left to explorers – open and not lighted – but rather accessible and very easy to visit, maybe with the help of a small torch. There is not a clear entrance (the area is not fenced), nor permanent staff on the site.

There are explanatory signs for basically all of the bunkers, in double Danish/German language.

The parking is ahead of the lighthouse, which is a different entity and operates with opening times you can find here. The parking is large and free. Climbing on top of the lighthouse is possible at a small fee – apparently only Danish Crowns cash accepted.

Together with a climb on top of the lighthouse, the visit may take from 1.5 to 3 hours, depending on your level of interest.

Skagen

The Skagen area is mostly famous for its location on the very tip of the Jutland peninsula, the natural northern end of continental Europe, and ideally as the geographical point where the North Sea and Baltic Sea join together. The long and quiet shores there and the population of seals contribute to making Skagen a prominent touristic attraction, often crowded with visitors from Denmark and abroad.

What people going there may not expect is the presence of a number of massive firing positions from the years of the German occupation! These are concentrated along the eastern coast, and include firing position for 120 mm coastal guns, overlooking the Skagerrak strait.

There are also a fire control bunker, which has drifted to the shoreline, as well as radar support bunkers.

Unfortunately, these installations have been left to the elements and – most sadly – to vandals. Except for their huge size, there is not much left to appreciate.

But there is more related to the Atlantic Wall in Skagen. A former hospital bunker has been partly refurbished and converted into a very interesting smaller museum on the local battery.

Inside, you can first appreciate the special size of the doors and corridors, made to allow moving stretchers around.

Put on display are several items related to the history of the Skagen fortress. There are uniforms from the time, photos from the years of operations, and everyday items left over by the Wehrmacht.

Some of the rooms have been reconstructed, and provide a vivid impression of the original appearance.

Among the exhibits are also some relics from a downed British aircraft.

Getting there and moving around

Visiting the Skagen battery is easier from the small parking Hvide Fyr, Fyrvej, 9990 Skagen. This parking is free. Going on the Baltic shore from the parking means a five minutes walk along a prepared path. A quick walk with a look to the abandoned battery would take about 20 minutes.

You may either walk to the tip from there, or better move your car to shorten the walk, going to the huge dedicated parking area where the road N.40 ends. This parking is not free.

You will find the Skagen Bunker-Museum in the former hospital bunker immediately to the southwestern side of the parking. Website here.

Visiting may take about 30-45 minutes, an interesting small detour from the local natural attractions.

Bangsbo

Comparatively less fortified than the North Sea coast, the eastern cost of Jutland is the place of a primary military and commercial port named Frederikshavn. This is also a starting point for travelers going to Norway from central Europe.

Here the Germans installed one of the few strongpoints on this side of the peninsula. What makes the so-called Bangsbo fort unique among the Atlantic Wall installations is the fact that three of the four original guns in the coastal battery are still in place!

The main area of Bangsbo fort, where the coastal battery is located, can be found to the south of the town, and is somewhat similar to Hirtshals (see above). Both are located on top of a cliff, with a significant area to the back dedicated to command, living and service bunkers.

Today, some of these bunkers have been completely refurbished. These include the command bunker for the local commander of the Kriegsmarine (the German Navy). This is super-interesting, with many artifacts from the time, from military gear to swastika-marked dishware, from maps to photographs of general Rommel – who superintended the construction of the Atlantic Wall – visiting the installation, and much more.

Much interesting is especially the reconstruction of the command/meeting room.

Scattered over the premises of the military area are cannons and several strange items, like a tank turret intended to be placed on top of a defensive Tobruk.

There are a refurbished hospital bunker and reconstructed living quarters.

The firing control post roughly at the center of the area is another highlight, having been completely refurbished, with plenty of Nazi insignia and original material.

To the back of the bunker are a living and command area, whereas the front part is an observation deck.

The firing positions with guns are numbered from Nr.1 to 3. They are based on 15 cm coastal guns, installed in 1944, replacing older and smaller pieces.

The guns can be walked around. The cartridge supply slides to the back of the firing chamber are still in place.

Guns Nr. 1 and 3 are similar, whereas the central gun was taken from a Danish cruiser cannibalized by the Germans in Kiel during the war. Today, it bears a greenish paint.

There used to be a fourth cannon with a field of fire of 360 degrees. Trace of a platform can be seen, as well as an anti-aircraft gun.

The fort shares a border with an active military area, so a part of the original installations cannot be visited. Others are open only for those visiting on guided tours. These include a radar-supporting station. Others can be entered, but are basically empty.

A minor part of the Bansgbo fort is located north of Frederikshavn. It is a partially preserved anti-aircraft firing station. This was made of four firing places and a central fire direction point. The latter is still visible at least from the outside.

One of the anti aircraft guns is also in place. The rest of the installation has been filled with land and made inaccessible.

Getting there and moving around

The major part of Bansgbo fort can be found south of Frederikshavn. It can be accessed from Bakkevej, which ends with the parking of the museum. Website here. The area can be walked and accessed with a ticket. There are picnic facilities and a small shop. Guided tours are offered at pre-defined times, see the website. You can get a good impression even by walking around on your own, but some bunkers can be accessed only with a guide. I did not join a guided tour, and all the pictures above are from a self-guided visit.

The site is not huge, but very interesting thanks to preservation efforts. It may easily deserve a 2 hours visit.

The anti-aircraft site is located north of Frederikshaven, and can be reached from Nordre Strandvej. You may park on the large free parking made for the local beach. This smaller installation may be visited in 10-15 minutes without a ticket.

The Border Forts of Czechoslovakia Against Nazi Germany

The Maginot line – a line of forts running along the French border with Italy, Switzerland, Germany and Belgium – is a widely known example of military engineering from the inter-war period (see this chapter). The adopted construction technique, based on reinforced concrete pillboxes with walls several feet thick, half interred to decrease visibility from above, field cannons and anti-tank defensive guns, witnesses the great consideration given to tanks and aircraft as attack weapons.

Due to the fast movements typical to the new strategy of the German army since the beginning of WWII, the Maginot line is mainly remembered for having not been involved in any major action, and having being largely bypassed. As a matter of fact, the German opted for a bypass also because the line was in place, so it was not as ineffective as it is often thought.

What is possibly even less known is that similar defensive lines were built in earnest in other European countries, before and even during WWII, after the Maginot line had failed to stop the invading German army. The enormous Salpa line, built by Finland against the Soviet Union, was probably the last and most effective to be completed (see this chapter). The Stalin line, prepared by the Soviets against Germany in Belarus, is another example. Another country who invested much in this type of deterrent was Czechoslovakia.

To understand the drivers of the design of the huge line of forts envisaged by the Czechoslovakian government of the mid-1930s, one should take a look at a map of Europe from the time. After the defeat of WWI Germany had managed to keep significant parts of todays Poland. The border between Germany and Poland ran close to Gdansk – aka Danzig in German -, and the province of Lower Silesia with the town of Wroclav – Breslau in German – were undisputed German territory. This means that todays border between the Czech Republic and Poland used to be actually a border between Czechoslovakia and Germany in the years before WWII.

With the turmoil preceding the infamous Munich Agreement and Nazi Germany claiming the right to control ‘Sudetenland’ – a large part of the peripheral territories of todays Czech Republic – in 1937 the Czechoslovakian government quickly started the construction of a huge system of forts to protect the border.

The concept was pretty similar to that of the Maginot line, with extensive underground tunnels to shelter soldiers and ammos, facing to the surface with reinforced concrete bunkers with different purposes, including observation, artillery shelling with field cannons, mutual protection with short range anti-tank cannons, machine guns and grenade-throwing tubes. There were also bunkers for accessing the tunnel system with resupply. About 10’000 light fortifications were actually built, more than 200 heavy fortified positions and a handful of heavy artillery positions.

The geopolitical situation in Europe got worse quickly in 1938, with the annexation of Austria in spring and finally the Munich Agreement, which caused the dissolution of Czechoslovakia. As a result of this internationally approved de facto German invasion, the works on the defense line were halted by the Wehrmacht. A relevant part of the hard construction had been completed, but most of the bunkers were still unarmed or lacked some software – air filters, ammo supplies, everyday items for the troops, etc. – and were not serviceable.

Most of the ironworks, including especially all heavy-metal turrets, were salvaged by the Germans. Some of the cannons found their way to the Atlantic Wall. The most massive concrete bunkers were used to test new weapons. As a result, the majority of the most sizable structures are still today in a partly damaged shape.

Some of the bunkers came to life again in the 1970s, when re-founded Czechoslovakia, that time a satellite country of the USSR living under a repressive and hard communist dictatorship, started a low-paced conversion of some of the structures into nuclear shelters for top ranks of the military and political hierarchies.

Notwithstanding these incidents, todays Czech Republic is duly proud of the significant work which was carried out in the difficult late Thirties. Very much was done for the little time available, and the quality of the design and construction is remarkable. While most of the sites are open only rarely, there are some where you can step inside and enjoy an interesting visit. This chapter covers with photographs and text five larger fortified complexes along this anti-German defensive line, from a two-days visit taken in August 2018.

Map

The following map shows the highlights of each of the five sites listed in this chapter. Please zoom in for greater detail. For the Bouda fort I could not spot and pinpoint on the map all the pillboxes you can easily visit from the outside – this are covered by vegetation.

Stachelberg

The Stachelberg site is located about three miles north of the small city of Trutnov. The fort should have consisted of a main entrance and peripheral shooting positions, some of them linked by underground tunnels, to defend the area of the Giant Mountains. Construction works were terminated much before completion, so the surface bunkers forming the ensemble are actually not connected. Yet the major installation, a bulky infantry positions with provision for anti-tank artillery, provides access to an extensive system of half-prepared tunnels, which gives you a clear picture of the size and capacity of the complex.

The site is open to the public, and the ticket office can be found right inside this huge major bunker. From the outside, the volume of this pillbox is particularly stunning. Also interesting are the anti-tank obstacles, which used to be placed along the border line and between the forts, to trap invading columns in a position where anti-tank guns could be most effective.

This multi-level bunker is also place for a little museum on the fortifications, mainly based on explicative panels and scaled models of weapons and of the entire bunker complex. It covers the history of the fortifications, and explains most technical features of their construction. There are no weapons or other software – they were either not installed before the construction works were stopped, or salvaged by the Germans.

The tunnels can be visited on a guided tour only, starting from inside the main bunker with a descent of several tens of feet along a flight of stairs, originally made at the time of construction. The tunnels unfold on the sides of a major, perfectly straight initial track. Some of the lateral halls, intended to store ammos as well as for sleeping the troops, are very large and close to completion, whereas others are just sketched.

The tunnels were dug in the rock with the help of explosives. The next step in the construction works would have been a layer of concrete from the pavement up to the ceiling of the tunnels. This is present today only close to the entry point, at the bottom of the access stairs.

There are at least other five smaller pillboxes which have been preserved to some extent in the Stachelberg complex. They are accessible with different timetables, and do not provide access to the underground – by design, some of them should have.

One of the pillboxes has been colored in a very bright camouflage. I could not find out whether this used to be the standard, but it looks pretty unusual and not really mimetic… There are also refurbished connecting trenches between the smaller bunkers.

The concrete base of a never built bunker can be found not far from the parking area.

Getting there and moving around

Getting close to the complex is really easy, the area is very scenic and a popular destination skiing, and for nature trail hiking in summer. There is a parking on road N.300 from where the museum-fort can be reached with an almost flat, 0.3 miles track.

The complex can be toured on the outside without restrictions. The main bunker has opening times, and the underground part can be toured only with a guide. The guide speaks Czech, but you are provided a leaflet with explanations in English, upon request. The tour takes about 30 minutes, and is offered on a regular basis, with several entries per day. They warn you about the inside temperature, but I found it pretty easy to bear with normal summer clothes. Website here, but you will need some Google translation to find the info you need.

Voda, Brezinka and Lom

These three forts are actually parts of the same system, built on the eastern end of the town of Nachod-Beloves, the major center in a local valley ending in Poland. Three items in the complex are typically accessible to the public.

The one closest to the town, on the bottom of the valley, is the Voda bunker. This is very convenient to reach, and is basically composed of a preserved typical infantry pillbox with provision for machine guns. The bunker has been painted in a credible camouflage. On one end it is possible to note the damage inflicted by the Germans, when they took out the metal observation turret. This kind of treatment – and damage – can be observed on a great many bunkers of the line.

Inside, the bunker has been turned into a local museum on the armed forces. There were border guards operating in the area, involved in skirmishes before and after the end of the war. The weapons originally intended for the fort are not in place, but there is an interesting collection of weapons, uniforms, motorcycles and other gear from the army corps operating around there over the years.

The Brezinka fort is possibly one of the most famous of the entire defensive line. The reason for that is that it was recently restored to look like it should have looked, if only it was completed back in the late Thirties. In the restoration process, weapons and system parts from other locations in todays Czech Republic were brought to the Brezinka site.

The visit of the interiors is really exceptional, even compared to the forts of the other defensive lines in Europe. The fort really looks like it could be put in operation today!

The first part of the visit of this two-levels artillery bunker will take you downstairs, where you can find the sleeping quarters for the troops with a food storage.

Close by, there are two rooms for the electrical generator and for the ventilation system. Here you can see the electrical compressor, with backup manual handles, and the huge air filters. These are multi-stage filters, where each stage was designed to stop different poisonous components in the air. The system is working, so you are given a demonstration of the compressor – interesting to get an impression of the incredible noise this system produced!

On the same floor there is also a telegraph system, which was used to communicate with other bunkers in the complex in case of failure of the telephone link. This system was capable of transmitting Morse signals to the other pillboxes next to it, projecting the signal into the ground and using it as a medium – there were no cables! This allowed it to work even if a direct electrical link was lost.

The upper floor is even more surprising, cause basically all weapons have been restored to their original positions. The Brezinka bunker featured two main firing chambers. The one pointing uphill features two heavy 7.92 mm machine guns Zbrojovka Brno Mark 1937, a very widespread and reliable weapon, with an operational range of 1’000-2’000 ft at 500-300 rounds per minute. These were used to target infantry movements along the border line, pinpointed by anti-tank obstacles. Fire direction was from the observation turret or via an optical aim system. The latter was extremely precise, but more expensive than the machine gun!

In presence of an impenetrable smoke curtain or at night, an open-loop aiming system could be used. This consisted of a board with a precise sketch of the view of the outside from the firing point, mounted on top of the machine gun. A calibrated needle pointer was used to align the machine gun with respect to the target, by simply pointing the needle on the intended target on the board!

The third machine gun is a light ZB vz. 26, a very popular light 7.92 mm machine gun. This was used for close defense of the fort access. There are also grenade throwing tubes for the same purpose.

The other firing chamber points downhill, and is supplied with a machine gun as in the first chamber, plus the assembly of an anti-tank cannon and another machine gun. The cannon is a 4.7 cm Skoda KPUV vz. 38, with an up to 1-mile range at 35 rounds per minute. It could pierce a 50 mm armor from 0.7 miles apart, and was a very effective weapon. This very cannon was already in place before the German invasion, and was taken by the Wehrmacht to the Atlantic Wall in Norway. It has been returned to its original location in recent times.

There are other two metal-reinforced embrasures in the bunker for other two ZB vz. 26s. On the same floor you can find a kitchenette and toilets for the troops, ammo storages, and two observation turrets. The latter feature a working movable floor, to allow tailoring to the height of the observer. The turrets were fitted with a periscope, and were used to direct fire. They weighed 21 tonnes each, and could withstand direct close fire from anti-tank guns!

Finally, the room of the commander and the telephone room – with an original machine from the Thirties – conclude the tour.

The Lom object, five minutes uphill with respect to the Brezinka fort, is another infantry bunker. It has not been refurbished to the level of Brezinka, but nonetheless it is used to showcase construction pieces, weapons and memorabilia from WWII years. The armored turret was taken away by the Germans.

Between the Brezinka and Lom bunkers you can find a section of anti-tank obstacles. The concrete base used to support them can be spotted in several places here and other sites of the defensive line.

Getting there and moving around

These bunkers, and especially Brezinka, are surely among the most interesting of the kind to visit, considering also their counterparts in France, Finland and Belarus.

The Voda site is easily accessible by car. The Brezinka and Lom bunkers cannot be reached by car. You can park on a street close to the trail-head and take the trail. Unfortunately, the road going uphill, albeit not uneven, is extremely steep and about 1 mile long. You should definitely take this into consideration when planning your excursion, even if you are physically well-trained. Very few beverages are available at the Lom site, which is five minutes farther uphill from Brezinka. Nothing is sold at Brezinka.

It is a pity they didn’t prepare a better access road, cause the site is surely worth a visit, and may appeal to the specialist and to the general public – especially children! – as well.

Only cash is accepted in all these sites. The Brezinka site is accessible only with guided tours. Tours were offered every 20 minutes in late August when I visited. You are given a detailed leaflet in English or German, in case you can’t speak Czech. The guided tour of Brezinka takes about 50 minutes.

The Lom site can be toured in 10 minutes, whereas the Voda bunker is worth a 20-30 minutes self-guided visit. Explanations are partly also in English and other languages in the Voda bunker.

Information on these three forts can be found from this website.

Hanicka

The Hanicka site features an extensive underground tunnel system, actually connecting the main entrance to some major peripheral forts. The ensemble includes one of the few most imposing firing units in the entire defensive line.

But what makes this site even more unique is the fact that, after having fallen into oblivion since the end of WWII, in the 1970s it was selected to be developed into a nuclear-proof governmental bunker – codenamed ‘Kahan’. The ensuing modifications altered greatly the appearance of the entrance bunker, and most of the systems you can see today in the underground part are actually dating from the 1980s.

The works on the conversion were carried out at a slow pace, and were actually not completed before the end of communism in Czechoslovakia, the collapse of the Czechoslovakian federation and the birth of the Czech Republic in the early 1990s. The bunker was soon opened to the public as a unique specimen of military building engineering from both WWII and the Cold War.

The tunnels can be be visited only with a guided tour. The original entrance to the tunnel, modified in the 1980s, is the starting point of the visit. The entrance to the bunker looked totally different before it was developed into a nuclear shelter. The modifications at the level of the entrance included the construction of a soft service building, with room for storages of trucks, armored vehicles and other material.

In the first hall giving access to the tunnels you can find weapons, communication systems, scale models of the site, maps and much more from both the ‘two lives’ of the bunker, in the 1930s and 1980s.

Access it through a thick, typical soviet nuclear-blast-proof gate. Inside, you see the nuclear-proof system allowed to seal a section of the entry tunnel close to the gate. The bunker was designed to allow long-term survival and operations for 300 people also in case of total insulation from the world outside.

A modern energy production system was put in place and can be seen together with water and gasoline tanks. The structure of the bunkers was not altered significantly, but the various systems date clearly from more recently than the Thirties.

There are also extensive sleeping quarters and a medical facility to the far end of the main tunnel, which was built in the side of a hill.

You finally come out in a former infantry bunker, reached climbing upstairs to the top of the hill. Here the embrasures and reinforcing panels of the firing chambers are still in place.

The next part of the visit will take you to some other smaller bunkers, visible only from the outside.

The visit ends in front on the major RS-79a bunker, a top of the line artillery bunker. This was provided with three embrasures for field guns. The size of this installation is really striking. You cannot visit inside this bunker.

It was somewhat damaged by weapons testing by the Germans, and never refurbished. You can see a nuclear-proof door substituting one of the original embrasures.

Back to the parking, it is possible to see from the outside an infantry bunker and examples of anti-tank barriers. This bunker is a rare example of a totally undamaged fort of the line – even the metal turrets are original and have been left in place by the Germans.

Getting there and moving around

The Hanicka complex can be explored outside with no restrictions, but the inside can be toured only with a Czech-speaking guide. They provide you a leaflet in English. The visit lasts about 60 minutes. Info on their website.

The entrance is via the original entrance bunker, modified in the 1980s. Reaching this point from the parking on road N.319 is a bit demanding, cause you need to walk on an unpaved road going uphill with a relevant grade for about 0.7 miles, then you have about another 0.7 miles walking on an easy, flat road. Differently from Brezinka (see above), they have a facility selling food, beverages and souvenirs close to the entrance. It’s a pity they just did not prepare a good road and a parking nearby the entrance.

Anyway, this site has much to offer and the visit is highly recommended, both inside and outside, for children and adults as well.

Bouda

The two nearby forts of Bouda and Hurka share a basically similar construction, and represent possibly the best examples of almost-complete forts in the defensive line. They are articulated around a straight tunnel, mined in the side of a mountain. The section of the tunnel next to the main entrance bunker features a narrow gauge railway, used to transport ammos and various supplies to the storage units inside. Deeper in, there is provision for sleeping quarters for the troops. To the far end of the tunnel you can get access to a group of fortified installations and artillery bunkers.

The Bouda installation can be visited thoroughly. The site is very big but more remote to reach than Hurka. Besides the access bunker, where the ticket office can be found, you can see a specimen of a metal turret. None of the original turrets has been left in this site, all have been salvaged by the Germans.

Soon after the beginning of the tour, you will see the terminal of the narrow gauge railway. The double track goes through a short incline. At the base of the incline the main tunnel starts.

Not far from the entrance you meet slots for sealing doors and related actuation systems. These were installed by the Germans and used to test their reliability and the effectiveness of their weapons on them. They had some cannons installed further in along the tunnel, and shooting on the armored doors they had installed.

The railway turns single-track, until you reach a major storage for weapons with a loading platform. One of the storage chambers has been reused to display a collection of weapons used in the forts and the corresponding armored embrasures.

Further on you visit a group of chambers originally intended to be fitted as sleeping quarters. The dividing walls and metal frames have been demolished at some point – or may be they were never installed – but some of them can be seen, original or reconstructed. In this area there is also a memorial to Czechoslovakian troops.

Further in the tunnel you reach another set of chambers, one of them with pieces of armored constructions and other heavy material from around the site. Then you get access to the stairs leading to a heavy artillery bunker.

What you see here is the cylindrical concrete box where the actuation mechanism and reinforced cupola should have been installed. The size of the construction suggest the total intended size of the field cannon assembly, really big! This should have been very similar to some of the installations in the Maginot line (see this post). There is also a firing chamber for lighter weapons where nothing remains except some metal coating.

The guide will lead you back to the bottom and inside the main tunnel, and ascending along another stairwell you can reach an observation bunker with provision for light weapons. This bunker is in a better shape, and significant traces of the original soft construction are clearly visible.

Damage is due also to weapons testing carried out by the Germans, clearly visible from the outside.

Upon reaching the surface, you will be directed along a walk through the exteriors of the bunkers in the fortress, including the incomplete heavy artillery bunker, with the large concrete pit from visible above.

Finally, you access one of the bunkers, which appears pierced and heavily damaged from the outside. On the inside the firing chamber is fairly well conserved, with the original embrasures for machine guns still in place. The wall is pierced presumably by a shell or mine.

This very bunker was used also for testing high-yield explosives, and as a result of a huge explosion it shifted sideward of a few feet, without collapsing and with no alterations to its general shape – really sturdy! You can clearly appreciate the shift by going down in the stairwell!

You will then return to the main entrance with the ticket office where the visit will finish.

Getting there and moving around

The bunker parking can be found very easily driving north of the road N. 11 between Cervena Voda and Cerkovice. The area is popular for nature trail hiking, and the fort is also a popular attraction. Following the road signs, you will be driven to an observation tower on top of a mountain.

From there, the entrance to the bunker can be reached only by taking a trail which descends along the northwestern side of the mountain. The distance to cover by foot is a good 1.5 miles, so this should be taken into consideration when planning your trip. You have to go uphill on your way back to the parking, so the trail is more demanding when you are leaving. There are signs on every crossing, so you should not get lost. By the way, the walk is really nice, going in the trees with some bird-eye views on this beautiful countryside!

Once at the entrance of the bunker you can find refreshments and souvenirs. The bunker can be visited only with a guide. They are offering three options for the visit, each of them adding something to the other, yielding a difference in time. I took the most complete tour, and it took about 180 minutes.

You are provided jackets for staying inside – even though the temperature is not extremely low, especially if you are wearing technical trekking clothes, which are recommended for the preliminary trail to the entrance. The jackets are dirty, so it’s better to bring one of your own, as they almost force you to have something to cover in!

The tour is offered in Czech, with explanations in English provided on all panels and on a leaflet you can borrow inside. There is a fee for taking pictures, but both this and the entry ticket are rather cheap. Further info on their official website.

Hurka

The Hurka fortress is an installation pretty similar to the Bouda site, at least considering the inside part. After some years of closure following WWII, the Hurka site was converted into an ammunition depot in the 1960s. The modifications inside include some demolition work on the soft walls and frames, so the structure is mainly composed of large vaults.

The tunnels can be visited only with a guide. The visit starts from the original gate of the underground facility, where all supplies could be placed on a narrow-gauge convoy. An external loading platform can be spotted, together with specimens of anti-tank devices and of the reinforced observation turrets.

Inside, an incline leads to the initial part of a long straight tunnel. The exhibitions provide an impressions of an ammo storage, and there are also weapons and armored embrasures from the fort.

An interesting exhibition prepared in one of the halls is about the activities of the agents of the Czechoslovakian government in exile during WWII. This included launching paratroopers over the territory of the former Republic, tasked with establishing contact with dissident anti-Nazi movements, and carrying out high-risk, top-priority missions. A pretty famous mission they were tasked with was the assassination of Reinhard Heydrich, a top-ranking SS, since 1941 responsible for the administration of the annexed territory of todays Czech Republic. A bloodthirsty, feared and hated figure, he died in hospital soon after having being shot in June 1942 in an operation codenamed ‘Anthropoid’. All the spies involved in the operation were later killed, and terrible retaliation actions were taken by the Nazis on the local population. An international movie was produced on this subject in 2016.

You don’t get access to the firing positions from inside, but you can visit them from the outside on your own and with no restrictions.

A pretty rare feature is a ‘top of the line’ artillery bunker, with three shooting embrasures on one side. This bunker is today standing severely damaged from German fire, inflicted during weapon testing. The bunker was actually de-interred by the Nazis to expose its walls, and perforation cannons were tested on it. Among them, the so-called Röchling shells, with a high perforation potential, adopted operationally but used very rarely in action by the Germans.

The other artillery positions are scattered on a grassy area on the side of a hill dominating a local valley. You can see the damages inflicted by fire testing, and the empty boxes of the metal turrets salvaged by the Germans.

Getting there and moving around

The tour of the underground starts from the original access bunker, which can be reached just north of Kraliky on road N.312. Convenient parking outside. The underground can be accessed only with a guide. The ticked office offers also food and beverages. More info on their official website.

The firing positions can be toured on your own. They can be accessed driving about 0.3 miles north along the same N.312 road to the top of the hill, and turning left on an unpaved road. You will soon see a bar with a prohibition sign for cars. You can park nearby on the grass and proceed by foot, you will meet the fortification with an almost flat walk of 0.15 miles. There are signs with multi-language explanations close to each of the bunkers. The place is really nice, and the walk is highly recommended.

Forts of the Maginot Line

Soon after the end of WWI, the government and the top-ranking officials of the victorious French Army set plans for a defensive system along the eastern border, which would protect the nation from future invasions. The ambitious plan was initially based on a line of reinforced concrete forts placed along the border with Italy, Germany, Luxembourg. Construction started in the last 1920s, and the defense system was named after Henri Maginot, ministry of war at the time and a major advocate of the project, who died well before its completion in 1932.

Construction works continued till at least 1935 on the Italian and German sectors. Soon after, in 1936 due to the re-negotiations of the alliance with Belgium, the line was partly extended along the border between France and Belgium, but it never reached completion, thus failing to seal that sector of the border – which might have been possible only by reaching the coast of the Channel.

When the first thunders of war resounded in Europe in 1939, the forts of the Maginot line were reinforced further. The German Army planned an attack accounting for the presence of the line, and when the invasion of France was enacted in May 1940, a small diversionary army was sent against the French forts, while most of the Wehrmacht moved quickly through the forests of southeast Belgium – the Ardennes – finally entering France in the region of Sedan, next to the western extremity of the French defensive line. So the immense defensive system was outflanked in about three weeks, and an armistice between France and Germany followed soon in June 1940.

The Maginot line is composed of 108 major forts – ‘ouvrage’ in French – plus many more smaller installations. These bunkers had often different characteristics depending on the region, and were interred to an extent depending on the local characteristics of the terrain. Typical features of these forts are turrets with cannons and periscopes. Larger forts have usually two separate entrances for the troops and for supplying goods – shells, grenades, kerosene for the electric generators, food, medical supplies, etc.. These forts could house more than 1’000 troops each. Larger bunkers were often connected by a network of underground tunnels with smaller observation or firing positions, or reinforced barracks. There was also a dedicated telephone communication network all along the line.

Many forts of the line never sustained attacks, while some did. Some were even used in the closing months of the war by the US Army, as strongpoints during field battles against the retreating German Army.

Today, many forts of the line are preserved as national monuments. Some of them are open as top-ranking museums, some have been entrusted to local societies of enthusiasts which allow to visit them on a regular or limited basis. Some are usually shut and inaccessible except by arrangement.

This chapter is about a few forts of the Maginot Line in northeastern France visited in 2016. These highlights provide an insight on the typical construction of these defensive installations. Featured are many photographs taken during these visits.

Sights

Ouvrage de la Ferté

This smaller fort is probably the one in the Maginot Line which saw the most intense action. Located in the beautiful countryside north of historical Sedan, on the border with Belgium, this fort is where the invading Wehrmacht inflicted a first major blow, entering French territory in Spring 1940. It was in the focus of a direct German attack between May 18th-19th, 1940, and no one of the French soldiers in the fort survived.

This installation, located on top of a hill, is composed of two main blocks, connected by an underground tunnel. The interior can be visited only on a guided tour, while the exteriors can be walked freely. The visit starts in the visitor center,  with a very nice animated movie telling the story of the fort, and of the momentous events of May 1940 it was involved in.

Then you are taken to the entrance of the bunker nearby. Getting closer, you are shown original defensive obstacles originally placed along the perimeter of many forts of the Maginot Line. There are six lines of rail beams stuck vertically in the ground, to stop tanks and vehicles, plus lines of barbed wire against attacking troops.

The entrance is through a bunker – Block 1 – emerging from the side of a hill. On top there are thick metal turrets for observation and rifle/machine gun firing. The entrance is through a smaller drawbridge, leaning over a dry moat. This is a distinctive feature of many similar forts of the line. An attacker close to the main door would find himself on the line of fire of anti-tank and lighter arms shooting through sealed loopholes in the wall of the bunker, and vulnerable to grenade attacks, which could be slipped through specially built inclined tubes. From the apron ahead of the bunker you can spot in the distance another concrete bunker part of the same group, about 1 mile away to the southeast. It cannot be visited.

Once inside you can see the shooting chamber opposite the wall close to the main door. Original light weapons are still in place – an anti-tank cannon and a machine gun. Close by there are the dormitories for the troops, the office of the commander and other service rooms, including bulky filters for the ventilation system.

During the fight, a grenade exploded inside the bunker, and this produced an extensive damage. Some non-structural walls collapsed, and what remains can be seen today. The ensuing fire was the final cause of the French disaster during the German attack, as the gas masks of the French troops were not designed against carbon monoxide resulting from a usual fire – most soldiers died from asphyxia.

The guide will drive you to the other block, walking along the connection tunnel. Block 2 features a revolving turret, which could be also retracted for sealing the bunker when necessary. When extracted, it exposed the barrels of various light weapons. This turret can be accessed if you are sufficiently agile. It was put out of combat by applying explosives which stuck the revolving mechanism – the turret has since then assumed a slightly banked attitude.

The guided tour ends after exiting through the door of Block 2. Moving around on top of the construction, you can see the clear signs of the German shelling on top of the turrets. Also the print left by a pack of explosive stick to the side of the revolving turret, but causing little damage, can be clearly spotted.

Between the two blocks, on the side of a local road crossing the site, a further concrete bunker with a small door – this time totally inaccessible – can be found. Opposite the road, there is a monument to the French soldiers who were killed in the attack.

Getting there and moving around

This site is really worth visiting also for those with a general interest for history, and it offers a very good insight on the specific features of the Maginot Line for technically minded people as well. The guide is very knowledgeable, and provides explanations in English also during visits in French. The place is managed as a modern museum, website here. The guided tour will last approximately 45 minutes. Allow more for touring the outside on your own and taking pictures. It can be reached along the road connecting Villy and La Ferté-sur-Chiers, less than 20 miles southeast of Sedan.

Ouvrage Simserhof

This is one of the big forts – ‘gros ouvrage’ – of the Maginot Line, located close to the German border. It was dug in the side of a hill, with two separate gates. The lower one at the foot of the hill was for supply, where the top one, close to the top of the hill, was for the troops. Both gates are reinforced concrete bunkers with loopholes for light artillery to defend the apron ahead of the entrance.

The place has a modern visitor center. The visit – only possible with a guide – is articulated in two parts. The first is a tour of the lower level, which used to be the storage for ammunitions as well as anything needed to supply the activities going on in the fort. This level has been converted into a dynamic exhibition, with sounds, a narrating voice, some visual effects. It is toured conveniently sitting on a cable car. The second part is a classic guided tour of the top-level, and it will start from the top entrance.

The inside of the fort is huge, and the tour is pretty extensive. You are shown the firing chambers besides the entrance, many tunnels, dormitories, living quarters for the troops, medical rooms, the rooms for the electrical generators, and many other service rooms. Remarkably though, you are not shown the artillery installations in the peripheral blocks.

Getting there and moving around

The museum is a prominent tourist attraction in the area. The visit to the lower level is more for children and people with a very general interest for 20th century history. The original setting was changed deeply to host a modern dynamic exhibition, which may not appeal to more technically minded subjects. The visit to the top part lasts about 1.5 hour, and is maybe too hard for kids. Many technical details are provided here and many items shown. Yet the fact that you cannot access any artillery position – at least when I visited – is a bit disappointing. Everything in French only when I visited. Info and timetables for visiting from their website. The closest sizable town is Saarbrücken, Germany, about 30 miles northwest of the site.

Ouvrage du Four à Chaux

This is an intermediate size fort, which hosted around 600 men in the days of operation. The visit – only possible with a guide – is very interesting, as the fort has many characteristics typical to larger installations of the Maginot Line – like Simserhof, see above – but it is more compact and easy to visit. Furthermore, during the visit you are shown all areas of major importance, covering the housing part, as well as the artillery control and firing part.

Much like larger forts, there are two entrances at two different levels on the side of a hill. You get inside through the top one, for troops. Access is by a drawbridge over a small artificial dry moat. From there, you are shown a series of long corridors and tunnels, along which you can find the dormitories and technical rooms.

A special feature is an escape tunnel, built vertically and reaching the top of the hill from the core of the fort. The tunnel is actually made of two twin parts, where the first was designed to be filled up with debris coming from the top of the hill in case of an attack, leaving the other free. This way escape was possible even after the emergency exit had been specifically targeted you enemy fire, causing the debris to fall inside. Further features include the big filters of the ventilation system.

The firing control area can be reached following a corridor going gently uphill. Here you are shown the technical situation rooms from where war operations were coordinated. Several panels and cutouts provide an idea of the structure of the fort.

Then you get access to the ammo storage. Here ammunitions for bigger calibers were put in canisters which were moved thanks to a rail hanging from the ceiling. Larger used shells were conveyed from the cannon to a storage area throwing them on a slide.

One of the retractable turrets is still perfectly working. The guide will operate the mechanism, showing how the turret can be moved up and down, and also how it can rotate. A closed circuit camera shows the turret from outside, thus allowing to better appreciate the effect of the mechanisms you see standing inside. This part is very interesting, and provides a good idea of how the fort worked during a battle.

The guide will finally drive you to the exit through the lower entrance originally for resupply, which is reached going down an inclined tunnel, used to load trolleys full of ammunitions moving them from the storage level to the operative quarters of the fort.

Close by the exit you can find an American M41 tank used as a gate guardian!

Getting there and moving around

The visit of this fort takes about 2 hours and it is very interesting. The museum is possibly less famous than others in the Maginot Line, which makes it more enjoyable, as groups are smaller and the staff is more dedicated. On the other hand, opening times are more limited, you can find information on their website. The visit was in French, but the guide answered my questions in English, plus you are provided a detailed paper guide in English – and probably other languages as well – for the time of the tour. The fort is on the premises of the town of Lembach, about 20 miles north of Strasbourg in the northeastern corner of France, right on the border with Germany.

Casemate Esch

This smaller reinforced artillery position is only rarely open to the public. Yet even from the outside it makes for a pretty unique sight. Actually this installation found itself in the middle of a storm in January 1945, when the 14th Armored Division of the US Army was stopped by the German army in the area of Haguenau during operation ‘Nordwind’, conceived by the Wehrmacht to repeat the success of the offensive in the Ardennes of May 1940. Many found shelter in this fort as a fierce tank battle raged all around.

Heavy damage resulting from intense shelling can be clearly spotted on this relatively small reinforced concrete building. A M4 Sherman tank has been placed on top of the bunker as a memorial.

Getting there and moving around

The barracks can be visited only on Sunday during the warm season. A view of the outside may be interesting, especially if you have already an idea of what a Maginot fort looks like from the inside. The place can be spotted easily on the side of D-28 less than 1 miles southeast of the small village of Hatten, some 15 miles north of Strasbourg. Information through the website of the larger Schoenenburg fort. For the outside, a tour of 15 minutes should be enough.

Abri de Hatten

This site is actually an extremely interesting WWII and Cold War museum, centered on the reinforced barracks in the village of Hatten, part of the Maginot Line. Inside the barracks, which can be toured on your own, you can find some of the original rooms rebuilt with their original furniture, especially a dormitory, a kitchen, medical facilities, air filters and power generators.

Due to the big size of the bunker, some rooms have been used to host extremely interesting exhibitions. These are about the life in the area in the times of the German occupation. Pictures and rare original artifacts with Nazi insignia are part of the collection. A unique German map of the world from 1941 is displayed – showing with the Swastika as the national flag of Germany, and many borders in Europe looking very different from now!

A room is dedicated to the wreck of a Messerchmitt Me-262 Schwalbe, the worlds first operative jet engined fighter. This aircraft was downed nearby the fort in the closing days of WWII. The two jet engines make for an interesting sight, plus there are many components of the avionics system originally on board this very aircraft, really futuristic at the time.

Another room showcases detection and communication gear from the Cold War years, and from both sides of the Iron Curtain. This recalls the fact that, soon after WWII, France decided to keep the largely untouched Maginot Line as a defensive installation against the Soviets. Having grown obsolete after nuclear stockpiles had begun to be produced also in France, the line was finally decommissioned by the early 1960s.

The premises of the reinforced barracks are scattered with further interesting items, including cannons of several makes and bores, anti-tank, anti-aircraft and heavier field cannons, from France, Germany, the US and the Eastern Bloc.

There are a MiG-21 and a Mil helicopter from the communist German Democratic Republic (GDR), a French Dassault Mirage, several antennas, a Soviet surface to air missile, more trucks from the GDR. There is also what appears to be a partly authentic border control booth with national insignia from the former border between possibly West Germany – maybe somewhere in Berlin – and the GDR.

There is a small memorial building dedicated to a group of soldiers of the French Army which after the armistice with Germany in 1940 were integrated in the Wehrmacht, and later sent to fight on the side of the Germans against the Soviets on the European Eastern Front. Due to the very harsh conditions of that sector of the front, many would never come back.

There are also two further buildings in the museum. The first is about the Maginot Line, with a comprehensive – and very interesting – collection of models of its various types of forts and reinforced structures. The second is on WWII, with remains of a downed Republic P-47 Thunderbolt, German transport vehicles, and many artifacts and weapons.

Among the most peculiar items on display there is a parachute for pigeons. These birds were extensively used for communication between occupied France and Britain. British birds were parachuted in France. If they fell in the right hands, they could be loaded with a message and launched. Their instinct would then guide them back to their home base across the Channel. Some of these birds even received military decorations for their bravery in this vital service!

Finally, a small collection of heavy army vehicles are kept in operative conditions by a local society of enthusiasts. These include US half-tracked vehicles, trucks, an American M60 and a Soviet T-34 tank!

Getting there and moving around

This unique, one-of-a-kind collection can be visited on a self-guided basis. Depending on your interest, a visit may take from 45 minutes to more than 2 hours. A website with some visiting information is here. There location is on Rue de l’Abri, immediately to the west of the village of Hatten, 15 miles north of Strasbourg. Most explanations are in French and German, plus scant signs in English. Please note that they accept only cash.

Fort de Mutzig – Feste Kaiser Wilhelm II

While not a part of the Maginot Line, the history of this fort is interesting, for it was erected by the Germans at the end of the 19th century, when the regions of Alsace and Lorraine – now part of France – had been lost to the German Reich following the French defeat in the Franco-Prussian war of 1870. It was designed and built as the most technologically advanced fort of its time. The construction was based on concrete instead of masonry, which made it capable of withstanding heavy shelling from the most modern and powerful howitzers of its age. It was made of three sectors, erected on top of a hill not far from Strasbourg, and was part of a defensive line built around that city against the French. It was dedicated to Kaiser Wilhelm II.

This immense structure featured two batteries of four heavy 150 mm howitzers and fourteen 105 mm cannons in specifically designed turrets, plus lighter observation and firing turrets. About 1’000 men stationed in the fort, which saw limited action in WWI and was ceded to France in 1918. Correspondingly, it changed name to Fort de Mutzig. At the beginning of WWII, it was regained by the invading German Army, which occupied it but later sent the cannons to the Atlantic Wall. It was bombed by the Luftwaffe in the closing days of WWII, but it basically went through the turbulent first half of the 20th century without sustaining any major damage. It was later abandoned and re-opened as a museum, frequently updated as more sections are restored.

It is today one of the largest and best preserved examples of early concrete forts – actually a good example of WWI military architecture, as construction techniques remained very similar until after WWI.

Visiting is possible only in guided groups. The visit will take you to the northern sector, where you can see the firing chamber for defending the gate, and a series of rooms including the living quarters of the troops stationed there. There are a the dormitories, a medical room and even a bakery. Most writing from the time is in German, and most machines bear the name of a German brand! You can visit the original toilet – even there, no privacy was allowed, to prevent the troops from committing suicide by always keeping a watch on them.

Inside the many empty rooms, there are exhibitions of artifacts like models of the turrets, reinforced observation posts and weapons from the original supply of the fort.

Interestingly, the original electric generators have been carefully restored together with the power-plant control panel – very nice, really from an older age!

The tour of the exterior will take you to the top of the fort, where observation and firing turrets can be seen from the outside.

Finally, a battery of four 150 mm howitzers is approached and visited.

Getting there and moving around

The fort can be reached on top of a hill about 12 miles west of Strasbourg. The road going uphill starts between the villages of Mutzig and Dinsheim-sur-Bruche. The guided tour – the only way to visit – takes about 1.5 hours. The visit will be extremely interesting for the general public and more technically minded people as well. Website with information here.

The Estonian Aviation Museum

A nice and lively university town in the heart of the Estonian countryside, Tartu has really something for every kind of tourist – including those interested in aviation history. The Estonian Aviation Museum, or ‘Eeesti Lennundusmuuseum’ as they write it in the tricky local idiom, boasts a substantial and heterogenous collection of aircraft preserved in exceptionally good condition, which will not leave indifferent even the most knowledgeable aviation expert.

Having being for long a socialist republic in the realm of the Soviet Union – and today sharing a border with Russia – Estonia had access to massive surplus reserves after the end of the Cold War, so it is no surprise that Soviet aircraft are well represented in an Estonian museum. This already might appeal to western tourists, for the exotic, menacing silhouettes of MiGs and Sukhois are not often to be found except in less accessible spots in the former Eastern Bloc. Yet some more unexpected and rare models have been added over the years, including some SAAB aircraft from Sweden which are authentic collectibles.

The following photographs cover almost every plane that was there in summer 2017.

Sights

Most part of the collection has been preserved in a cleverly designed structure, made of small open-walled hangars with translucent canopies. The aircraft are illuminated by natural light, helping much when taking pictures, but they are not exposed to direct sunlight, rain or snow, which tend to damage both metal and plexiglas on the long run. Furthermore, the lack of doors and frames allows you to move around freely, and the place is not suffocating nor excessively warm.

The aircraft are basically all from the Cold War era, but some of them have outlived the end of the USSR and were retired more recently. The portraits are grouped here roughly based on the nationality of the manufacturers or aircraft mission.

Designs from the US

The American production is represented in this museum firstly by a McDonnell Douglas F-4 Phantom II, operated by the West-German Luftwaffe. The General Electric J79 turbojets have been taken out of the airframe, so you can see them separately.

A pretty unusual sight, also the antenna and electronic group in the nose cone have been taken out and are on display. This Phantom is a F-4F, a version specifically developed for West Germany from the basic F-4E. The former inventory number was 99+91.

Another iconic model on the menu is a Lockheed F-104 Starfighter, formerly from the Italian Air Force. This exemplar is actually an Italian-built ‘S’ version, and among the latest to be retired by the Aeronautica Militare. The engine, again a J79, is on display elsewhere in the museum. An unusual crowd of instruction and warning stencils populate the external surface of the aircraft.

Soviet Military Models

The majority of the aircraft on display were designed in the Soviet Union or other countries of the Warsaw Pact.

Two aggressive aircraft include a MiG-21 and a MiG-23. The first, present here in the colors of the Polish Air Force, is a MiG-21bis Fishbed, the latest development of this fast delta-wing fighter/light-interceptor.

Possibly one of the most ubiquitous fighters of the jet age, the MiG-23 Flogger is part also of this collection. The aircraft you see in the pictures is a MLD variant, representing the last upgrade of this iconic fighter, which was also the basis for the very successful MiG-27 design.

It bears the markings of the Ukrainian Air Force, therefore it is likely an ex-USSR aircraft. The engine is sitting besides the aircraft, and two rocket canisters are placed beneath the fuselage, close to the ventral GSh-23 twin-barreled cannon.

A less usual sight is a MiG-25 Foxbat, a super fast interceptor/recce aircraft. Conceived in the late Fifties when the race for speed was in full swing, it was developed into a high performance platform to counteract the threat of the SR-71 Blackbird. It was built around two massive Tumansky R-15 afterburning turbojets, rated at a pretty high wet thrust of 110 kN, resulting in an incredible top speed around Mach 3.2! The aircraft is pretty sizable, and you can appreciate that looking at the picture of the main landing gear – search for the cover of my Canon wide lens close to the ground and compare sizes!

The menacing silhouette of this huge bird, with red stars on the vertical fins and a bare metal fuselage, will likely make relive in you an ‘Iron Curtain feeling’!

One which will not go unnoticed is a Polish Air Force Sukhoi Su-22M4 Fitter in a flamboyant, very colored livery. This massive fighter-bomber represents the export version of the Su-17M4 built by the USSR for domestic orders.

Despite the shape, roughly similar to that of the MiG-21 also on display, the size of this aircraft is much bigger – you might think of Su-22 as a case for a MiG-21…

Soviet bombers are represented by a pretty rare Sukhoi Su-24 Fencer, which is today still in service in Russia. The example on display bears the markings of the Ukrainian Air Force, meaning it was once a Soviet aircraft.

This massive twin-engined beast outsizes all other military aircraft on display. The aircraft is on display with three support tanks under the fuselage and the inner wing pylons.

A less common sight is a Yakovlev Ya-28P Firebar, a long-range intercept version of this multi-role platform from the early Sixties. This design is very interesting, with a four-points undercarriage and a very long nose cone, where a radar system for a target-tracking and missile guidance system was located. The two turbojet engines are mounted in cigar-shaped underwing pods. The relevant sweep of the wing suggests a significant speed capability, yet many variants of this aircraft were developed to exploit also its good range performance. The antenna originally placed in the nose cone is on display besides the aircraft, which bears original Soviet markings.

Soviet Transport Aircraft

Two aircraft which could not find their way in covered shelters mainly due to their bigger size, are a Tupolev Tu-134A-3 and a Yakovlev Ya-40. Both can be accessed, so you can get a view of the inside, including the cockpits.

The Tu-134 twin jet, with its distinctive glass bulge in the nose ahead of the cockpit, has been for long a ubiquitous aircraft in the USSR and in many countries of the Eastern Bloc. The exemplar on display was taken over by the Estonian company Elk Airways, created after Estonia left the USSR.

Notwithstanding this, the aircraft betrays its Soviet ancestry and ownership in every particular, from the all-Cyrillic writings to the hammers and sickles here and there, from the design of interiors to the exotic cockpit, painted in a typical lurid Soviet green and with prominent unframed black rubber fans for ventilation.

The Yak-40 is an interesting three-jet executive/small transport aircraft. The one on display went on flying for at least some good 15 years after the collapse of the wall in Berlin.

The internal configuration features an executive room ahead of a more usual passenger section and tail galley. The style of the cabin and of the pure analog cockpit is really outdated for todays standards!

A rugged workhorse still flying today in many countries is the Antonov An-2, a single propeller, radial-engined, biplane tail-dragger transport. There are two of them in the collection. One is under a shelter and can be boarded. The interiors are very basic, but the visibility from the cockpit is very good especially for a tail-dragger with an engine on the nose.

Swedish Aircraft

An unusual chapter in air museums except in Sweden is that of SAAB aircraft, which are represented in this collection by two iconic models, a Draken and a Viggen, and an extremely rare, very elegant Lansen. All are in the colors of the Royal Swedish Air Force.

The Saab 35 Draken features a very distinctive double-delta wing, and was developed in the Fifties for reaching a high supersonic speed. The design turned out to be pretty successful, and was operationally adopted primarily as a fighter by Sweden and other European countries as well.

The one in the collection is painted in a bright yellow livery. The infra-red pod under the nose cone of this aggressive attack aircraft looks like the lidless eye of an alien!

The Viggen is a an attack aircraft from the late Sixties, developed for the domestic military needs into some sub-variants. With the JA 37 version displayed here, the Viggen went on to constitute the backbone of the intercept fleet of neutral Sweden, and was retired only in the early 2000s. The aerodynamic configuration features a prominent canard wing, and the Viggen was notably the first in such configuration produced in significant numbers.

The most unusual of all three SAAB designs on display is surely the SAAB 32 Lansen. A very neat design from the Fifties, loosely recalling the Lockheed P-80 and the Hawker Hunter, the Lansen was a jet fighter of the early Cold War developed specifically for Sweden and gaining a good success. The ‘E’ version on display was converted from the original fighter variant (‘B’) for the ECM role, and kept flying almost until the end of the 20th century. The green painting of the Royal Swedish Air Force is really stylish, definitely adding to an already elegant design.

Soviet Surface-to-Air Missiles (SAM)

Curiously enough, an extensive collection of SAMs is part of this rich collection. All major missiles from SA-2 to SA-6 are represented, some of them in multiple exemplars. The size of these missiles, especially the oldest, is really striking. They are stored outside, besides some cases for missile transportation, deployable radar antennas, and what appears to be a flak cannon from Hitler’s Germany – a bit of an outsider…

Jet Engines

Many of the engines of the aircraft on display have been taken out of the corresponding airframes and put on display besides the plane where they used to belong, or in a dedicated part of the museum together with others. The J79 belonging to the Italian-built F-104 can be recognized from the Italian plaques on many components.

Many soviet engines bear markings in Cyrillic, and one of them, a larger turbofan which does not fit in any bird on display, has been cut to show all components.

More…

More aircraft in the collection include some Mil and Kamov utility helicopters, a BAe Hawk of the Finnish Air Force and other trainers mainly from countries of the Warsaw Pact, some of them now on the civilian register.

A further notable aircraft is a Dassault Mirage IIIRS from the Swiss Air Force – with multi-language French and German stencils all over.

There are also some anti-aircraft guns, armored vehicles, tanks, and other curios items to whet your appetite!

Getting There and Moving Around

The museum can be reached 10 miles south of central Tartu on road 141, about 15 minutes by car from there. There is a free parking area nearby the entrance. As remarked, the collection is well-kept and somewhat publicized locally. There is a website with all information in English. The time required for visiting may vary from 45 minutes for a quick tour to 2.5 hours for photographers and those with a specific interest in the matter.

Among the most unequivocal signs of the oppressive communist dictatorship in the former German Democratic Republic – ‘GDR’ or ‘DDR’ in German – are probably the many buildings once operated by the STASI, the German cousin of the well-known Soviet KGB.

Being a state security service by its very name – STASI stands for ‘STAat SIcherheit’, or state security -, this organization was responsible for the capillary control over the behavior of the citizens of the GDR, to the aim of counteracting any threat to the communist rule. It was mainly composed of a para-military staff and of an extensive network of informers – so extensive that actually about 1 out of 180 in Eastern Germany worked for the STASI, while by comparison in the USSR 1 out of 595 worked for the KGB. The main goal of this agency was keeping the statu quo, hence any suspect behavior of East-German citizens, deemed subversive with respect to the communist rule, was reported, investigated and usually suppressed.

People found guilty of acts against the State – i.e. against the communist government – were often sentenced to years of imprisonment. This meant that prisons and camps flourished in the GDR, as people got arrested and at least kept for interrogation just for having received western newspapers or having colored their rooms with posters of American pop singers. How the STASI came to know of similar ‘violations’ was by means of informers, who triggered secret investigations carried out with ‘James Bond gear’, like cameras and microphones hidden in coat buttons and bags. Microphones and cameras were also usually installed in the walls, chandeliers and doors of the houses of suspected subjects.

This huge institution was among the most feared and hated – as well as expensive to run – in the GDR, and soon after the reopening of the border and the demolition of the wall in Berlin in 1989 many of its buildings were occupied by the population. To deny responsibility in the unfair trial, imprisonment and confinement of many citizens, the staff of the STASI began ‘burning’ its archives immediately, but they were so extensive that this rapidly turned out to be impossible. The STASI was disbanded among the first governmental agencies of the GDR in the early months of 1990, even before the two halves of Germany were merged. Finally the archives were made publicly available during the process of the German reunification. Many people came to know they had been carefully observed and spied in every movement during their everyday life.

Today, some of the most prominent buildings once operated by the STASI are open to the public and represent an interesting and worrying memento of this chapter of the history of Germany. The following photographs are from some such sites I visited over the years from 2013 to 2023.

STASI Headquarters, Berlin-Lichtenberg

The headquarters of the STASI occupied an extensive citadel composed of many big, multi-storey buildings. Like the KGB, the tasks of the STASI weren’t limited to internal state security, but also to border protection – a very serious business in Eastern Germany, as you can see from another page of this site dedicated to the German inner border – and espionage activities abroad. The various directorates occupied their respective buildings in the citadel. The place is in a semi-peripheral district of former East Berlin named Lichtenberg.

The main building hosts a museum of central relevance on the topic, where you can find much data about the history and the impressive size of this agency, as well as spy gear – for instance mimetic microphones for listening to conversations in private houses. The stories of some of the victims of the communist surveillance machine are also reported. Envelope-opening devices and rags for preserving the odor of those arrested for watchdogs are displayed in showcases.

Probably the highlight of the museum is the apartment and office of Erich Mielke, the director of the STASI from 1957 – well before the wall was erected in Berlin – up to the dissolution of the GDR. Many original directional offices have been preserved and nowadays can be visited.

The place is very evocative and retains much of the disturbing ‘GDR atmosphere’, typical to this and other similar installations. The number of visitors is much lower than close to Checkpoint Charlie and the DDR museum near the Berliner Dom, which are mostly cheesy tourist attractions with comparatively little content. On the contrary, in this museum you can still easily perceive the commitment of the GDR goverment towards its own survival, and the proportion of the oppressive apparatus that was created to this aim – here you clearly understand the STASI was a serious business and changed the life of many people.

After visiting the museum in the central building you may have a look around to the exterior of other buildings in the citadel, today mostly unused, abandoned or partially occupied by private businesses – I guess the place still retains for many people a very negative aura.

Getting there and moving around

Today the citadel can be reached very conveniently by car or with the U5 (between the stops Magdalenen Strasse and Frankfurter Allee). The museum is fairly modern and well presented, but as of 2015 when I visited the ticket could be paid only cash and some explanations were in German only. Inside the museum there is no air conditioning, and it can be very hot and uncomfortable in summer. Parking is not a problem in front of the main entrance or nearby. Website here.

STASI Prison and Restricted Area, Berlin-Hohenschönhausen

The second largest quarters of the STASI are located in yet another outer district of former East Berlin. Old photographs of the area clearly show that this part of the town was interdicted to visitors not connected with the business of the STASI – there used to be fences and gates all around, cutting some of the roads entering the district. Besides some directorates and administrative buildings, this citadel hosted a prison and a labor camp. The former was the main STASI prison in East Berlin, and those who were arrested on account of suspect activities against the State were usually carried here, where they had to withstand interrogations.

This place is really grim and appalling. It looks like the staff of the prison had just left. Everything from what you see to the smell of the cells, offices and interrogation rooms is totally evocative of the original GDR atmosphere.

The STASI became the owner of the place in 1951, after the Soviets, who had managed the occupied territory directly after the German capitulation in 1945, left control of many administrative functions following the creation of the GDR. Under the Soviet rule, in the years of Stalin between 1945 and 1951, a labor camp was set up here and the main building of the prison – a former canteen for Nazi staff – opened for business. More than 20’000 people passed through this installation between 1945 and 1951, many of them on their way to deportation to the USSR.

Under the control of the STASI, the camp was dedicated to non-political prisoners, where the prison, enlarged in more instances as the STASI citadel was growing up, was for the ‘enemies of the State’. More than 20’000 people were imprisoned here between 1951 and 1990.

The place can be visited only on guided tours, offered on a regular basis also in English. Following the tour you can see various imprisonment cells. The worst – and really inhumane – from the times of the Soviets are in the basement of the main building, with no windows and no ventilation, where many people were crushed together waiting for interrogation or deportation.

The majority of the cells date from the era of the GDR, and are more modern. As the main business of the prison was that of extorting confessions, the prisoners were progressively brought in a state of psychological prostration. Preventing any form of communication was part of the treatment, so most cells for newly arrested people were for one person only. To isolate those arrested even more, when moving from the cell to the interrogation rooms and back the wardens observed special red and green lights, telling when there was somebody else in the corridors. This way the inmate would not see anybody except for the warden and the officer who interrogated him during all his or her stay in the prison.

Padded cells with straitjackets like in asylums were used in the process of extorting confessions, when the inmates were treated with drugs causing hallucinations and loss of physical control. These can be seen in the basement of one of the buildings.

Also visible are some cells with open top for spending half a hour per day in open air.

An interesting item presented in the exhibition is a minivan that was used for taking people quietly to the prison. The appearance and markings are those of a normal cargo van for transporting goods, whereas the interior is structured with micro-cells for arrested people.

Interrogation rooms are aligned on a corridor, and are extremely essential, featuring a shabby furniture. Greasy traces on the wallpaper and the smell of old fake leather heated by the sun is make the original atmosphere come alive.

A further wing is where a clinic for inmates was located. The clinic was of good level, with much technical instrumentation to manage several regular or emergency situations. The office of the director of this wing is another example of pure East German design. Most notably, the once omnipotent Erich Mielke appears to have been interned here following his arrest after 1989.

A one-of-a-kind exhibit is a railway truck for inmates. Besides the rather uncomfortable compartment design, with small chairs in a very little space, this transport was made really inhumane through the lack of air conditioning, the windows with bars and even a white glass, which deliberately created disorientation. These trains were artificially put on the lowest priority, so as to make traveling a painstaking experience for inmates.

The memorial is not central, so only those really interested in the history of the GDR, and of East Berlin and the STASI usually come here. Nonetheless, it is managed like a good level international museum, with guided tours, facilities for groups and a serious bookshop. Before taking the tour you are offered a movie telling the history of the prison in brief and showing the testimonies of former inmates. All in all a very interesting – and instructive – experience, surely worth a detour from the more touristic districts.

After visiting the prison, you may have a look around to the other buildings in this citadel. You can find a map in a cheap but interesting booklet they sell in the bookshop (‘The prohibited district’, by Erler and Knabe).

Getting there and moving around

The correct address of the prison building is Genslerstraße 66, Berlin. You can reach it easily by car. The neighborhood is primarily residential and not central, so parking won’t be a problem. If you have not a car, you can arrive conveniently with the tram line M5 from the most central districts. The correct stop is Werneuchener Strasse, and from there it’s about 0.4 miles to the gate of the prison. Website here.

STASI Prison Lindenstrasse, Potsdam

Behind an elegant façade like many others you can find in central Potsdam there is a prison comparable in size to the ‘main’ prison in Berlin Hohenschönhausen described above, and mostly unknown to the general public crowding this small and beautiful historical town.

This building was used as a prison by the Kaiser, the Nazis, the Soviets and finally the GDR. It was renovated and modified in many stages during its long history, and during WWII under the Nazi rule, some sections of the courthouse in central Berlin were transferred here, when the original buildings of the Nazi courthouse got damaged as a result of Allied air raids.

Differently from Hohenschönhausen, the prison in Potsdam is not part of a ‘citadel’, even though the KGB headquarters in the GDR were not far – actually they can be found close to Schloss Cecilienhof, Potsdam, now partly converted to luxury apartments and villas.

Another difference with respect to Hohenschönhausen is the style of the building, which dates back to older times. This is reflected in the plan and in many details of the construction, which at least from the exterior is very elegant.

Inside you can find Soviet cells in the basement – also here the most inhumane – and other cells packed along narrow corridors on several floors. In the inner courtyard there is a central block of open top cells for ‘recreation’, and traces of the original cameras and surveillance systems.

Something you may appreciate is the fact that you can visit the place on your own. Paneling with data or telling the stories of former inmates are totally in German, but you are given a leaflet with explanations and a map of the place at the entrance. Also a few original interrogation rooms have been preserved and can be seen.

The entry price is very reduced, so visiting is of course a must for the committed tourist, and interesting also for the general public. The place is ‘mimetic’ and not much advertised, so you won’t find the usual flocks of visitors, unlike the royal estates in Potsdam… Much recommended.

Getting there and moving around

The precise address is Lindenstrasse 54, Potsdam. It is in central Potsdam, so you may park at your convenience for visiting the district and have a stop there if you like. Similarly, if you are coming with the public transport system just go to the central district and walk to the place. Website here.

STASI Pre-Trial Prison, Rostock

Similarly to the prison in Potsdam, the anonymity of the façade of this building in central Rostock, placed to the back of a section of the courthouse still working today, is really deceiving. A prison capable of hosting more than 100 inmates can be reached today via a small door leading mainly to the offices of the faculty of the local university. Once inside the building you will notice a worrying fence on the side of the stairs going to the first floor, where you can get access to the prison.

Besides the many cells, it is possible to find a very interesting exhibition on the history of the GDR and of the STASI, with much data and stories from the time. Also many artifacts can be found, like spy gear, rags for preserving the odor of inmates for watchdogs to make capture easier, state bonds used to pay informers, and more.

The main function of the prison was that of keeping those arrested for interrogation until they were sentenced. More than 4000 people spent some time in this prison, mainly for ideological crimes, in the years of the GDR.

The place can be visited for free with an audio guide also in English. Some parts, including the open-top cells outside and the rigor cells in the basement can be visited only in a guided tour – as far as I understood, these are offered in German only.

On the top floor you can see an interesting exhibition on people who escaped or tried to flee the GDR by sea.

Getting there and moving around

Centrally located in Rostock – a lively city on the coast of the Baltic Sea – at a walking distance from Rosengarten. If you are moving by car, you can park on Hermannstrasse, and reach the door to the back of the courthouse block (opposite a small market). The door is heavy, so press it hard, it may be open even if it looks closed. Website here.

STASI Maximum Security Prison ‘Bautzen II’, Bautzen

Originally designed as a pre-trial and short-term court jail by the local government, the prison of Bautzen II was erected under the Kaiser to the back of the courthouse in the homonym town in the southeastern corner of Saxony, today very close to the border with both Poland and the Czech Republic. A larger penitentiary, named Bautzen I and originally conceived as a juvenile jail, was built around the same time in town.

With the advent of the Nazi dictatorship, both facilities began to be exploited for the prosecution of political dissidents, or to isolate elements of ‘inferior races’. Violence, intimidation and extorted confessions began to be the rule. Both branches of the prison of Bautzen fell under Stalin’s control at the end of WWII, and this corresponded to an exceptional increase in the number of inmates, which included a substantial share of former Nazi staff and opponents of the Soviet regime.

After the creation of the GDR, the facilities in Bautzen went on working as primary centers for the confinement of political prisoners, together making for possibly the largest detention center in the country. The smaller jail of Bautzen II, with slightly more than 200 single cells, was turned into a maximum security prison intended for the most dangerous ‘subversive elements’ of the whole state. While Bautzen I is still an active state prison of todays Federal Germany, Bautzen II has been opened to the public as a memorial.

The dreary access from outside is through three gates, and this adds to the perception of the place as really ‘no hope’.

Similarly to the prison in Potsdam (see above), Bautzen II can be toured on a self-guided basis, without a group. Most parts of the prison are opened, and several cells can be accessed.

Some of the cells retain the original furniture, even shabbier than the usual communist standard. The metal staircase in the middle of the prison building allows to better appreciate the size.

Besides rigor cells with additional bars and an incredibly small walkable area, some groups of cells are separated from others, with armored doors splitting the corridors in contiguous isolated sections. This was possibly a special feature of this maximum security prison. You can experience an unreal silence when sitting in a cell closing both the doors of the corridor and of the cell.

There are also some ‘common areas’ for inmates to work and stay, and an external courtyard divided in sectors, to allow inmates to spend some time open air, but without the chance to meet or see each other.

Getting there and moving around

The prison of Bautzen II is open as a national monument, a website with full information about visiting is here. I noticed that there are descriptions in German only throughout the prison, so you would better go prepared at least on the history of the place – starting for instance from the website – to get the most from your visit. The location is Waigangstrasse 8a, which is behind the courthouse of Bautzen, 0.8 miles to the east of the historical town center, conveniently reachable walking from the railway station and also by car. The area around the courthouse is mainly residential and parking can be found easily. Bautzen I is still today an active regular detention facility and cannot be visited.

A vital center of the Sorbs, an etnic group of Saxony and Brandenburg recognized by the German Federal Government, the town of Bautzen is nice to visit and rich of historical content. It is about 45 miles east of Dresden, and bolsters a picturesque, perfectly refurbished town center with medieval to baroque architectural elements.

STASI Headquarters, Dresden

The STASI headquarters and prison in Dresden have been developed starting 1945, originally as a prison for the Soviet NKVD (later KGB), on the premises of a former factory not far from the river Elbe and the historical district of the town – which would lay destroyed for decades following air raids in WWII. Similar to the prison in Lindenstrasse, Potsdam (see above), the underground floor of the former factory building was turned into a prison, with provision for a number of very basic cells typical to Stalin’s era, aligned on a narrow corridor.

Until the facility was handed over to the newly-formed GDR in 1952, the Soviets interned here mostly German citizens accused of cooperation with the defunct Nazi regime, as well as subversive elements, unfriendly with the Soviet controlling forces. As usual within a dictatorship, indictment was largely arbitrary and sentences extremely harsh – following arrest, most people were deported to forced labor camps of the Gulag system in the USSR, some were brought to Moscow to be hanged, and many were sent to provisional camps established in the ‘Soviet occupation zone’, later to become the territory of the GDR.

In this part of the exhibition it is possible to step in most of the cells, very small and essential.

A room is dedicated to the Gulag system, whereas another is a memorial for those taken to the Dresden prison and who reportedly did not survive the ordeal of the Soviet detention system, or where sentenced to death on the base of political reasons.

Also visible are some service rooms, like the bathrooms and rooms for the guards.

Along the corridor an emergency cable could be pressed by the guards at any time when in distress, triggering an alarm. From this part of the prison it was possible to access a inner courtyard.

Concurrently with the handing-over to the STASI, the facility was expanded, with offices and a modern multi-storey prison building.

Access for those arrested was via an inconspicuous wooden gate. An apparently innocent cargo van was employed for arrests. It can be checked out and it reveals provision for several segregated micro-cells inside. Once disembarked from the van, some prisoners may have had to wait for the prison check-in process inside mini-cells. Temperature in this area used to be – and still is – terribly hot in the summer.

Once inside, prisoners had to undress and undergo an accurate inspection in the check-in room. They were photographed for records in a special room, where they sat on a chair which was moved by the camera operator to obtain portraits at specific angles. Then prisoners were assigned dresses and slippers for their stay.

This prison acted as a remand (i.e. pre-trial) prison, with 44 cells on 4 levels.

Cells were for one, two or three people. Single cells were not customary from the 1970s on, except for rigor cells.

An example of the latter can be seen, with a small chair bolted to the ground and no windows. A special cell was that for writing letters, something that was possible only at prescribed intervals (e.g. once per week) and in this special room – obviously, all communications were checked and censored by the STASI. This cell features a small table, a chair, and a lavatory.

An uncommonly ‘comfortable’ cell was employed for foreign prisoners, who included those who had tried to help GDR citizens in their escape attempt, and who for some reason had got caught by the STASI. These cells had a window allowing a view of the sky – not possible through the special windows of regular cells – and a larger iron bed, instead of a narrow wooden berth.

Separated boxes in a walled courtyard outside were employed for letting the prisoners spend some minutes per day in the open air.

Walking the prison building you may notice that most of it is still original, including the purely-GDR linoleum floor, and the alarm system. The heavy curtains make the building dark and oppressing. The temperature in the summer is also very hot. The building is very silent, much resembling the original asylum-like feeling.

A routine operation in a remand prison was interrogation of the prisoners. Prisoners were insistently interrogated by STASI staff before formalizing an indictment. For the purpose, they were taken to the top floor of the building, along a few flights of stairs, up to the the interrogation rooms. Interestingly, the door giving access to this ‘bureaucratic’ part of the facility still bear seals (now reopened), put in the days of the revolution following the demolition of the wall in Berlin in 1989. The offices of the STASI, with material and archives, were sealed for criminal investigation.

Today, in this area a few original relics from the STASI operations can be found, like photographic film, nominal folders, stamps, keys, etc.

One interrogation room is still visible, whereas many others have been converted and are today employed for thematic workshops by the organization running the memorial.

As of 2023, the memorial is undergoing restoration, with the reopening of a larger part of the offices planned soon. Momentarily, it is possible to see the original grand auditorium of the STASI, a full-scale theater, with a typical GDR decor and even an original audiovisual apparatus. It is hard to imagine what kind of people could attend some symposium in an elegant room like this, just 50 ft away from prisoners confined in cells, non-criminals confined mostly only because suspected of having some arbitrarily-defined ‘subversive ideas’.

The quarters of the old NKVD prison are linked to the more modern prison building by a long underground corridor.

Getting there and moving around

The former STASI headquarter in Dresden is run as a memorial by a very active society, supported by various preservation bodies and associations. A professional website with much information, including a leaflet with a description of your visit in English, can be found here. A visit may easily take 1.5-2 hours for an interested subject. Many parts of the facility are accurately preserved and make for a very evocative memento. Furthermore, permanent and temporary exhibitions add to the experience and documentary value.

Visiting is possible on a self-guided basis, with explanatory booklets in many languages including English lent for the duration of your visit.

The memorial is located northeast of the historical district of Dresden, right on the northern bank of the river Elbe. The exact address is Bautzner Straße 112a, 01099 Dresden. However, access by car to the inside parking is possible only at these coordinates, (51.06688926262786, 13.782718227181237). Since access is from a major road where a U-turn is impossible, and the entrance to the parking is somewhat ahead of the official address, it is worth employing these coordinates for your nav, otherwise you might be missing the entrance to the parking, being forced to a pretty long tour of ‘one ways’ and ‘no turns’ before you get back to your intended destination.

Memorial ‘In der Runden Ecke’ – STASI Headquarters, Leipzig

Similar to its cousin in Berlin-Lichtenberg, the former headquarters of the STASI in Leipzig has been opened as a memorial. In this case, the building was not made on purpose, but converted from a pre-existing one. A decorated, elegant palace in the city center was chosen for the local brain of the repressive apparatus. The building features an angled facade, since the name ‘on the round corner’ – ‘in der Runden Ecke’ in German.

The entrance hall to the former headquarters has retained much of its original appearance.

The main part of the exhibition is immediately reached through the original reception office, which has been left willingly untouched since the pre-1989 era – including now dead CC-cameras, and two elaborated majolica murals with emblems of the STASI and some decorations.

The exhibition takes the ground floor of a wing of the building, i.e. only a small part of the original site. The office of a clerk has been mothballed preserving at most its original, shabby appearance, with a portrait of Honecker.

In an adjacent room, many rigs for covert mail and communication interception and inspection activities are displayed. These range from steam-pumping envelope openers, to fake postal stamps from Federal Germany, or even from abroad (to send false communications), and even fancier machines for reproducing signatures, looking inside parcels, etc. – every design betraying a really paranoid attention to details, and a true waste of exceptional engineering abilities.

A complete cell and photo studio – for mugshots – from the now demolished STASI prison in Leipzig has been spared for this exhibition, not much dissimilar from others on this web page (see above).

More artifacts on display include audio and image gathering stuff, ranging from micro cameras and recorders, to exceptionally compact, high-precision zoom lenses. Archived rags with the smell of repression victims in case of escape – for dogs – are another specimen from the STASI crazy inventory.

A room is devoted to the STASI huge paper archive, and to the silly, titanic effort to destroy the evidence of years of illegal spying activity as quick as possible, following the re-opening of the border. The solidified slime obtained from paper fragments is on display. Some very evocative pictures show the immense Leipzig archive and its conspicuous remains after the destruction attempt.

Two more rooms tell about the immediate post-WWII history in Leipzig, with pictures from 1945 with Nazi officials who committed suicide, as well as from the first stage of Allied occupation and Soviet administration – before the GDR was founded.

An interesting collection of artifacts concerning the Soviet-GDR friendship and alliance is really evocative of a luckily bygone era.

Finally, the corridor is full of interesting pictures, telling about the disinformation role of the STASI, border patrolling, and many other businesses this overpowered criminal organization was in charge of.

The building is today also seat for an agency managing the old STASI archive for historical purposes. Furthermore, the first floor and the elegant stairs leading to the top can be toured, with some display cases showing attractive Soviet-era artifacts.

The first floor in particular must have been an official meeting/reception area, or a director’s office. Part of the original furniture is still there, including a mural with the head of Dzerzhinsky, the founder of the Soviet Ceka back in Lenin’s time, and an inspirational figure for all fanatics of ‘state security’ in the communist world – an activity which was a synonym for violent prosecution of free will.

Getting there and moving around

The memorial is on the border of the pedestrian area in Leipzig city center. It is modestly publicized, but thanks to its accessibility, it might be easily included in a standard visit to historical Leipzig, and it is significantly populated by tourists. Entrance is free of charge, and its professional website is here. Despite the small size, for an interested subject visiting might take 2 hours or more. Free pictures are allowed, and an audio guide in English allows to get much from the visit even for people not speaking German.

STASI Bunker, Machern

The bunker in Machern is an underground facility built for the STASI in 1968-72 as an emergency headquarter, for keeping the chain of command and coordinate operations in case of a potential crisis. It represents a specimen of the level of commitment of the GDR government with respect to the preservation of control, and a witness of the huge budget made available to this particular ministry, inextricably linked to the government itself and pivotal in the survival of the oppressive GDR communist regime over its entire life span.

The crisis in Prague in 1968 possibly triggered the build up of a similar underground network by the STASI, which customarily operated in secrecy. The very existence of the bunker, located some 30 minutes driving from central Leipzig, was unknown to most. The inconspicuous visible part of the facility was deceived in one of the lots in a district of free-time homes for employees of a public company. It was discovered only following the 1989 revolution and the abolition of the STASI.

Compared to underground military installations, either of the NVA or the Red Army, the bunker is rather compact. However, it had provisions for about 100 staff in case of crisis, with a moderate ability to resist military-level attacks, including facing a nuclear war scenario.

The visit starts by accessing the grounds, where an unassuming little country villa of the GDR can be found, which acts as a check-in point, and as a ticket office.

Soon you may notice the presence of unusual gear on the premises. These include houses and training gear for dogs, cables for allowing leashed watchdogs along a pre-assigned watch pattern, a concrete sentry box, fire extinguishing gear, piles of fuel barrels, a deck for repairing vehicles, and a rather big grey hangar.

The latter hides the blast-proof double entrance to the underground bunker. Before stepping in however, it is possible to check out an impressive amount of spare parts aligned on shelves, with literally tons of interesting military-grade material – most of them clearly marked as Soviet manufacture. Many mystery boxes with writing in Russian can be seen. Rolls of barbed wire, metal nets, camo blankets, and other material for sealing and deception can be seen together with more technical material, including technical instrumentation.

A small collection of memorabilia from the STASI years is shown on site, as well as a permanent exhibition with technical schemes and organization details.

Access to the underground bunker is via a horizontal armored door and through a long flight of stairs. An airlock with two tight doors was installed for making the place blast-proof and seal it in case of nuclear attack.

Dosimeters and showers for decontamination can be found close to the entrances – there are two of them, both inside the same hangar.

The bunker was mainly intended as an intelligence center for crisis management. The flow information was guaranteed by a number of communication systems and facilities. Manned stations can still be seen in a number.

Beside communication facilities, the bunker features sleeping quarters for the STASI staff, a kitchen/canteen area, and a few offices and private quarters for the decision-makers – senior STASI officers. These offices offer a reasonable level of comfort, typical to the the bunkers from the era (see for instance Kossa and the Polish headquarters near Wolin, but a similar level of comfort could be encountered also on the western side of the Iron Curtain, like here in Britain).

The bunker is built mainly around a square corridor, with an array of long and narrow rooms, each dedicated to a specific function.

Soviet material can be found everywhere, including air filters and heaters.

Different from the previous sites bound to the grim and disturbing history of the STASI and of the communist-led repression in the GDR, this bunker offers an interesting perspective into the para-military domestic activity of this former backbone of the single-party government of that country.

Getting there and moving around

The STASI bunker-museum in Machern is a branch of the STASI memorial in Leipzig (see above).  An updated web page on this bunker can be found in the German version of the website of the Leipzig memorial (here), with updated information on the planned dates for a visit. The bunker is regularly open only on a few dates over the year, which are published in advance.

The visit allows to access the grounds, where explanatory panels are available in German, as well as the storage hangar and bunker. In the hangar, visitors are offered a short introductory video (in German). Afterwards, it is possible to visit the hangar and the bunker on a self-guided basis. Reservation is not required, but access is regulated on site by gathering visitors to form small groups, who are admitted to the bunker one by one to avoid overcrowding. Time in the bunker is more than enough to check-out the items on display, taking all the pictures. In all, a visit to this installation may take about 1 hour once on site.

Please note that they accept only cash for the ticket.

The location is in the countryside, about 10 miles northeast of Leipzig along the road B6. It is easy to reach only with a car or similar. There is a large parking there (51.376119908957726, 12.633996194227596), also serving the nature recreation area around. The entrance to the bunker can be reached from the parking with a .5 miles walk along a local road here (51.37857212168658, 12.644452664748663). No parking is possible on that road. Please note that the position corresponding to the bunker marked on Google Maps is largely inaccurate.

The bunker is located very close to the former Soviet base of Brandis/Waldpolenz (see here).

KGB Prison and Headquarters, Potsdam

This memorial is strictly speaking an outlier in this chapter, since it was never a STASI facility. Since their arrival in late April 1945, the Soviets installed a major intelligence and counter-intelligence center in Potsdam. An entire district was severed from the rest of this fashionable imperial town – which had fallen in the hands of the Soviets and later in the GDR. Its perimeter was fenced, the area provided with a guarded gate, and interdicted to everybody except authorized Soviet staff.

In it there were residential buildings, as well as central offices of the secret intelligence and security services of the Soviet Union in the heart of the GDR, and immediately on the border with West Berlin.

Today this exclusive residential area has been returned to its original function, except for a memorial, which has been prepared in the former prison originally built by the Soviets in a pre-existing, relatively little and unassuming building.

The Soviet secret services employed the prison from 1945 to the early 1950s as a remand prison for former Nazi collaborators, but also for German citizens considered dangerous or unreliable for the Soviet system. They were typically sentenced to years of forced labors and deported to the Gulag systems. When the STASI was created and took over the surveillance of GDR citizens, this prison was employed primarily for Soviet citizens considered as dissidents, including military staff. It is estimated that the Soviet population in the GDR totalled half million people in the late 1980s, therefore surveillance was not an easy task for the Soviets, requiring a dedicate apparatus with its own facilities.

The citadel and the prison in it went on operating until 1994, among the latest facilities to be relinquished by the then-Russian government.

The largely arbitrary indictment and sentencing of German citizens interned in this prison by the inhumane bureaucratic Soviet government of the years of Stalin indeed made many victims. Therefore, this place is primarily a memorial.

The shabbiness of the entire construction, typical to Soviet KGB prisons (see for instance here) is really striking. The visits starts on the first floor, where a number of cells can be seen. A rigor cell can be recognized by the lack of any light or ventilation. The ground was typically flooded with cold water, and the walls are covered in rough plaster, so that the prisoner could not sit on the ground nor lean against the wall.

On the top floor, former interrogation rooms today host a very interesting exhibition, with rich and detailed information in multiple languages including Russian and English. They cover the activity of Soviet secret services in the ‘Soviet occupation zone’, and later in the GDR and the Soviet enclaves in it. The brutal treatment reserved to many Germans, typically in the immediate post-WWII years under Stalin’s rule, is witnessed through striking documents, accounts and photographs. Among those sentenced to death were even schoolboys who did not want to learn Russian.

A focus is put on the structure of the law system of the communist dictatorship in the USSR, as well as on the mechanism of interrogations – including accounts of Soviet defectors.

Original memorabilia from the place include coats, special armbands for the staff authorized to enter the citadel, as well as original documents from the various ages of operation of the place.

In the basement are group cells intended for many people on their way to deportation. Graffiti from inmates can still be seen in the plaster.

A rigor cell which did not allow standing is also part of the exhibition.

A memorial to the victims of Soviet hardship has been installed on a side wall, whereas a modern visitor center completes the exhibition.

A thematic walk in the former Soviet citadel highlights through explanatory panels the original function of some of these buildings. Now returned to their original imperial splendor, they carry unsuspected grim memories of the communist era. Among the most notable features is the relic of a former small monument. Looking carefully, some of the houses still bear numbers on the facade according to the Soviet-style numbering of town blocks.

Getting there and moving around

The memorial is called Gedenk‑ und Begegnungsstätte Leistikowstraße Potsdam, and its professionally-run website is here. The address is Leistikowstraße 1 – 14469 Potsdam. Many parking opportunities on site. Reaching is easy also with public transport from Berlin. The prison is very close to the Cecilienhof palace.

The visit is on a self-guided basis, with much information available through the website, including options for smartphone-guided tour to the prison and to the former citadel. The permanent exhibition (in many languages) is rich and interesting, a detailed visit to the prison and exhibition may take up to 1 hour 15 minutes. A walk in the former Soviet citadel, today very enjoyable, may add 30-40 minutes for the more committed visitor.

Peenemünde Army Research Facility

Peenemünde is broadly known for having hosted the first ever large-scale research center and test ground for military rockets, missiles, flying bombs and innovative ordnance and weaponry in the world. The small town of Peenemünde is located on the island of Usedom, a nice, almost flat island on the shore of the Baltic sea, on the border between today’s Germany and Poland – ‘Peene’ is a river having its mouth (‘münde’ in German, from which the name of the place) where Usedom island is.

History – in brief

The Peenemünde site was a creäture of the administration of the Nazi regime in the late Thirties. It grew rapidly to a considerable size especially for the time. The site included an electric power plant, later used after the closure of the research center for supplying energy to the East German power grid, an airport, later converted into an air base and operated by the Air Force of East Germany, a sea port, a series of technical facilities for testing and producing all that was needed to assemble rockets, their systems and engines, as well as for preparing propellants.

There were also several launch pads for missiles and flying bombs, and last but not least, scattered over a broad area, housing for thousands of people, which included high-ranking technicians and people from academia – there was also an advanced wind tunnel -, military/SS personnel, as well as factory workers, including many prisoners of the regime.

The site was so large that a dedicated local railway was built and operated to allow people commuting, modeled on the urban railway of Berlin. The railway network was the third in size in Germany, following Berlin and Hamburg.

This enormous installation was directed by Wehrner von Braun, later to become a technical leader in the US research efforts in the field of rocketry, and a central character in the race for space opposite the Soviets.

Peenemünde was never an operative launch site – it was far too distant from potential targets in Britain for the limited range of flying weapons of those days – but due to its primary relevance as a testing and production site of the v1 flying bombs and later of the v2 missiles, the site became a designated target of very intense bombing raids.

The Peenemünde complex was severely hit in a series of air attacks launched by the Allied British and US air forces in the summer of 1943. After that, production was moved in forced labor camps in central Germany – Mittelbau/Dora being probably the most in-famous – whereas only research and testing was still conducted in Peenemünde, with plans to move progressively more and more equipment to other destinations scattered over the territory of the Third Reich, for which construction was started in the last years of WWII.

The Soviets captured what remained of the complex in Peenemünde at the very end of WWII in May 1945. By common agreement, the Allied put an end to rocket research in Germany, the Soviets materially blowing up every technical building still standing in the area, with the exception of the power plant, the airport and a few others. Parts of the machinery in the powerplant as well as almost all railway tracks were reportedly transferred to the Soviet Union.

Since then, the air base of the East German Air Force has been developed in more instances, adding aircraft shelters, a tower and other technical buildings that are still standing – the airport is today open to general aviation. The power plant was updated over the years by the Communist regime, becoming one of the most polluting plants in Germany, whereas the former launch pads and the area once occupied by technical buildings were rapidly reclaimed by nature.

The following photos were taken during a visit to the site in April 2016.

Sights

Museum

After 1989 and the German reunification, the power plant was soon closed, and a museum (Historical Technical Museum, website here) on the history of the Peenemünde site, recognized worldwide as the cradle of modern rocketry, was opened in it.

Among the few buildings of the Nazi era still standing today, the building of the ticket and book shop of this museum used to be a bunker for governing the power plant also in case of an air raid.

There are three main exhibitions in the museum. The open air exhibition, on the ground of the power plant, is composed of an original v1 launching ramp moved here from France, with a v1 flying bomb assembled from original pieces, a reconstructed v2 rocket, and a local train from the original local railway system.

In the photos it is possible to see the launch system of the v1, which was pushed to its take-off speed by a piston moving in a pipe underneath the bomb, in the body of the ramp. Mostly similar to modern acceleration systems on aircraft carriers, except for the piston was moved as an effect of a chemical reaction involving hydrogen peroxide, and not water steam as it’s most typical for aircraft carriers.

The second and third exhibitions are hosted in the building of the power plant – itself a significant example of industrial architecture from the days of the Nazi regime – and describe the history of the army research center and of the powerplant. The first of these two is the ‘central piece’ of the complex, no visit of Peenemünde is complete without a look at this exhibition.

In the photographs it is possible to see some of the artifacts in the exhibition about rocketry in Peenemünde. It is possible to appreciate the advanced technologies tested here already in those early years, including high pressure mixing of liquid propellants, graphite deflectors for thrust vectoring, inertial navigation systems, turbopumps for pumping the propellant into the combustion chamber at the correct rate. There are also original signs from the area.

Scaled mockups of all items tested in Peenemünde, much more numerous than the v1 and v2, add to the show, together with models of the former launch pads. Especially launch pad ‘VII’, used for the v2 rocket, was so well designed that it was adopted also in the US after the war as a blueprint for their own designs.

A visit to the complex of the power plant may easily take 2 h 30 min for an interested subject.

Former test grounds and launch pads

The launch pads were placed closer to the airport, very close to the northeastern shore of the island, to the north of the village of Peenemünde. Today, this broad ‘ghost area’ is partly fenced, surely not accessible with private vehicles, possibly accessible by foot. It is a kind of natural preserve, with much wildlife around.

The best way to explore this area, without getting lost in the trees and with a chance to spot what is still in place, is going with a society offering guided tours of the site, named ‘Historische Rundfahrt Peenemünde’ (website here). As of 2016 there are tours offered in German three times a day on a regular basis, but it is possible to arrange tours in English upon request at your preferred time – this was my only option as I don’t know much German. In my case, it turned out I was the only visitor on that tour, so I had the guide – a gentleman speaking a very good English, and with an incredible knowledge of many technical matters – all for me for the duration of the whole 3 h 15 min tour. You move mostly with a minivan, so apart from the bumpy road the visit is very comfortable.

The tour starts by the airport of Peenemünde, and you are soon driven into the site. With the help of a digital map, the guide will show where you are standing with respect to the buildings and installations that were originally there. You can see from the photos that Soviets took their job very seriously, so that very little remains of the original structures. You can recognize the original plan of the site mainly by the asphalted roads still in place today – albeit covered in dust.

The most prominent sight in the complex is surely launch pad ‘VII’, once used for the v2. It is possible to spot the containment banks all around the launch site. The concrete flame deflector is still in place, filled with rainwater. The walls of the deflector were water-cooled to resist the extreme heat of the rocket exhaust at takeoff. The water pump occupied a part of the lateral banks, together with measuring equipment and a sheltered observation deck. Still standing is a water nozzle used by firefighters in the – likely – event of fires due to malfunctions in the launching process.

A stone celebrates the launching of the first v2 missile from this site.

The rocket used to be moved to the launching position – above the flame deflector – with a special trolley. Multiple silos were placed around a common track made of concrete, built outside the perimeter of the containment banks. The trolley, loaded on a sliding platform, could move along the concrete track. The missile was collected from the assembly silo, the platform moved along the concrete track to reach the head of a short metal railway track where the trolley could be pushed to reach the flame deflector, in the middle of the containment banks – see the photo of the model above. Like the flame deflector, the concrete guide is still standing today, filled with rain water.

Other interesting sights of the visit are the experimental launch ramps of the v1, placed to the northernmost part of the island, right behind the beach. A first experimental ramp (type 1) was totally made of concrete, and was clearly not adopted for operational use, being too difficult to build and manage. Other two ramps, not so different from one another, were the first examples of types 2 and 3.

Type 3 was adopted operationally and deployed to the coasts of France and Belgium. Inert concrete warheads used in test flights can be seen in the photos, left from the age of testing.

You can see here that all ramps pointed directly to the Baltic sea. Telemetry towers were installed on the neighbor islands of Oie and Ruegen for tracking the experimental flights and taking measurements. Two such towers that are still standing today can be spotted from here in the distance, you can see them in the photos.

Before leaving, having shown a great interest for the topic of aeronautics, I was given the opportunity to tour an incredible exhibition of weapons, systems and artifacts from the area they are putting together in a small farm surviving from the days of WWII – where rabbits were bred for feeding the staff and for making fur for airmen. As of May 2016 this was not yet open to the public.

Among the artifacts you can see in the pictures from this exhibition, TV-guided bombs, experimental solid propellant rockets, a piloted v1 and tons of other incredible items. This shows once more that many technologies later become widespread had been tested here much before they started to be massively used. Also preserved are some parts of aircraft downed during the raids of 1943.

Maybe after finishing with the tour it is interesting to have a brief look to the airport, where the control tower possibly from the Nazi era and some aircraft shelters are still standing. The place can’t be walked freely for it’s still an active GA airport, but part of the former base is being used as a testing track for sport cars and can be approached safely.

My tour lasted more than 3 hours, but at the time of booking my English tour I was offered also shorter options.

K-24 Juliett-class Soviet submarine
Heading to Berlin or the former GDR? Looking for traces of the Cold War open for a visit?

This submarine is moored in the port of Peenemünde, a five minutes walk from the entrance to the power plant. This is reportedly the only Juliett class submarine existing today, so visiting is an absolute ‘must-do’ for the committed tourist (website here).

Furthermore, the condition of this unit is still very good, making for an interesting and unusual visit – a unusal fact is that all is written in Cyrillic alphabet, with many ‘CCCP’ factory signs on the labels of the gauges and of the technical stuff. Juliett submarines were designed in the Fifties and operated till the collapse of the Soviet Union in the early Nineties, with a capability for launching cruise missiles with tactical nuclear warheads directed to target ships or coastal targets, from a distance of some hundred miles. They were conventionally powered with large diesel electric-units.

Having been designed after WWII, they are much roomier than German U-Boots from the Nazi era, hence the visit is ok also for claustrophobic people. You can see two launch tubes in a deployed position to the back of the ship.

Visiting may take between five minutes and 1 hour depending on the level of your interest.

Note

A visit of these three items at a reasonable pace but without running may easily fill a day schedule. I know there is much to explore and see on your own in the area of the former complex, but I could only dedicate one day to this site during my trip. I would recommend doing at least the same for an interested person.

In any case, the island with its Baltic shores and light is nice and relaxing, so I would recommend planning a day for Usedom also in case you are not interested only in military history.

Getting there and moving around

The island of Usedom is much larger than the area of the former research complex, which once occupied the northernmost extremity. The island can be approached by car with two bridges in Anklam and Wolgast from mainland Germany, or from Poland. It is very easy to get there by car.

Once in the village of Peenemünde, it’s easy to spot the massive building of the power plant. K-24 can be reached with a five minutes walk from the entrance of the power plant. The place is very popular, so there is a large parking just besides these two attractions.

The pick-up point for the guided tour of the former research center is by the small airport, which is located north of the village, a 1.5 miles drive from Peenemünde. Free parking besides the small office building.

I couldn’t imagine a more convenient way than having a car for moving around, but the island is reportedly very crowded in summer. A train can be used to reach some of the villages on Usedom, so you may consider also this alternative.
