Military Collections in Sweden – Fourth Chapter

The geographical location of Sweden on the map of Europe naturally put it on the front line of the Cold War. With a very long shoreline taking most of the northern border of the narrow waters of the Baltic Sea, since jets made their appearance on the stage of military strategy, this Scandinavian kingdom found itself just minutes away from the Soviet Union (which at that time engulfed also today’s Estonia, Latvia and Lithuania), as well as from Communist-led Poland (see for instance this post) and German Democratic Republic (much covered on this website, see for example here).

Keeping up with a long-established tradition of neutrality, dating from soon after the age of the Napoleonic Wars in the early 19th century, during WWII and, afterwards, with the beginning of the Cold War, Sweden managed to stay out of any major explicit alliance with the Western Nations. During the Cold War, by continuing this non-aggressive policy, Sweden was a relevant contributor to the overall stability in the Northern European region.

Considering the early accession of Norway and Denmark to NATO to the West of this sector, in the momentous years following WWII when the USSR was still ruled by Stalin, who had just aggressively sealed the fate of the newly-conquered dominions in Eastern Europe, the independence of Finland, sharing a long, militarily untenable land border to the East with the Soviet Union, was particularly precarious (see Hanko, in this chapter). While leaning towards the West and being historically adverse to Russia, Sweden carefully avoided entering NATO, while still establishing commercial links notably with the UK and France for military supply. This attitude, and the increased geographical distance between NATO and the USSR, likely helped to dilute tension between the two opposing blocs in the area – which nonetheless peaked at some points in history before the demise of the USSR – thus mitigating the chance of an outbreak of hostilities, despite a massive military presence on both sides.

Concerning the military budget however, the neutral policy of Sweden did not by any means entail renouncing to self-defense. A solid economy with natural resources and a well-established tradition in mechanical industry and warfare supply, Sweden was perfectly conscious of the need to sustain its geopolitical role with a credible military power, such to deter as much as possible an aggressor, and ensure survival in case of an open war, even in the high-technology war scenario developing in the post-WWII years. Spared the devastation brought about by WWII, Sweden’s strategy planners and industry started in earnest developing especially ground and air forces.

The development of the air force and the air defense system was carried out in an integrated fashion, within the STRIL (Stridsledning och Luftbevakning, which might be translated into Combat control and Air surveillance) programs. Updated over the years (notably the first being the embryonic STRIL 40, followed by -50, -60 and -80, corresponding roughly to those decades in the 20th century), this program embodied the need for monitoring and self-defense. Considering in particular threats coming from the air, airspace monitoring and related information gathering/processing were carried out through a purpose-designed network of stations and command centers. Having ascertained the type of threat, the Air Force would deploy a proportional countermeasure, accounting for its plans for self-defense. This could be carrying out an intercept by scrambling aircraft – something which happened regularly for the decades of the Cold War, following violations by the Warsaw Pact forces – or, in case of an open aggression, for example deploying SAMs to down attacking aircraft.

The evolution of the STRIL program over the years reflects the development in the technology of the threats, and of the defense system itself. This passed from being based on optical detection and early jets, brought to an intercept point with purely verbal communication, to several types of radars linked directly to situation rooms, and purpose designed aircraft, which starting from the SAAB J35 Draken in the 1960s could receive data of an aggressor via datalink.

After the end of the Cold War and the collapse of the USSR, changes in the geopolitical scenario meant the partial scale-down of the Armed Forces, yet also the update of the still existing Sweden’s surveillance system based on more modern technology. Notably, Russian scouting operations and temporary violations of the air space of Sweden have continued over the years, thus giving a practical reason for maintaining a minimum level of alert.

As shown in previous chapters on this site (see here, here and here), retracing the fascinating history of the Armed Forces of Sweden through visits to dedicated museums, collections and surviving sites, especially the Cold War decades did leave behind some traces, which are still there to be seen.

In this chapter, two sites with many links to the history of STRIL can be found. One is a perfectly preserved installation, a node in the airspace monitoring network in Åstorp, close to Helsingborg. The other is the exceptional technical collection of the Missile Museum in Arboga, run by former staff of the Armed Forces of Sweden and passionate technicians, and preserving in a lively and rich exhibition countless items retracing the history of military missiles, as well as many aspects of air defense, especially in Sweden over the Cold War years.

Photographs have been taken from both sites during visits in the summer of 2025.

STRIL Sector Operation Center (SOC), Åstorp

On the origin of the STRIL system – Brief historical note

The STRIL system, an acronym standing for Stridsledning och Luftbevakning, which might be translated into Combat control and Air surveillance, was first systematized in 1948, following the preliminary program STRIL 40, with its roots in the experience gained and in the technology of WWII. A key component of it was the availability of air surveillance stations, physically built as soft manned tower constructions, where staff of the Optical Air Guard, typically voluntary women, kept the airspace under watch (similar to the Royal Observation Corps in Britain, see this chapter). Before 1948, information from these visual intelligence gathering points traveled to a number of decision centers (Jaktcentral, precursors of the Sector Operation Centers) by wire, where additional staff of the Guard managed to create an overall picture of the situation and threats, and military officers could eventually authorize a reaction, typically scrambling aircraft for an intercept, in case of an airspace violation.

With the quick and dramatic evolution of military technology in the first years of the Cold War, the STRIL 50 system, started in 1948 and fully implemented by the mid-1950s, inherited, developed and structured the existing network. The territory of Sweden was divided in 21 sectors, which were covered by optical information gathering points, in the form of 1’300 Air Surveillance Stations (Luftbevakningsstation, or LS in short), i.e. towers like in the previous system, manned by the same Optical Air Guard, which however was now under the control of the Air Force. Arranged in a hub-and-spokes fashion, these stations reported to Sector Operation Centers (or SOC, Luftförsvars Gruppcentral, or LGC), of which 50 existed over the national territory. Finally, the command and control (C2) centers were 11 so-called Air Operation Centers (Luftförsvarscentral, or LFC), where the military staff could authorize and coordinate a counteraction against a threat.

Radar systems, both range-finding and altitude-finding, were a major technological addition of STRIL 50. Initially imported in the form of light or movable systems with moderate capacity, a constant investment in this technology brought to Sweden premium British (Marconi, Decca), Italian (Selenia) and later US (ITT-Gilfillan) technology. Radar information was a mainstay of the STRIL 60 program, largely integrating usual optical LS towers, thus strongly increasing the coverage and range of the pre-existing monitoring system. The level of automation increased steadily over the 1960s and 1970s, merging range, altitude, speed and direction information of a potential threat, and presenting them on a digital plotter to human controllers, directly in the LFC C2 centers. At the beginning of the 1960s, datalink parameter transmission allowed controllers in the LFC to provide flight data of an aggressor to the cockpit of the J35 Draken, avoiding easily detectable verbal communication, for an increased level of effectiveness.

In this constantly evolving technological scenario, the implementation of the OPUS system allowed to still profit from the pre-existing LS and local LGC centers. Within that system, the human operators where supplied with a threat labeling system, allowing them to digitally communicate data of whatever optically detected air traffic, including position and direction. This was automatically collected and filtered in purpose-implemented electronics within the LGC, visualized on a local plot, and forwarded after filtering to the LFC, thus integrating the automatically-processed radar information available to the C2 centers. Perceived also as a safety layer in case of an attack to the inherently vulnerable radar stations, the Optical Air Guard stayed until after the end of the USSR, finally disbanding in 1994.

A visit of the site

What you see in Åstorp is an original, perfectly preserved Sector Operation Center, i.e. an LGC, which stands as an ideal specimen to understand the structure and technology of this element in the defense network implemented through STRIL.

The Center is in a bunker built underground in the rock (as typical to the early Cold War era, see this chapter), and is accessible via a steep and narrow flight of stairs from an unassuming, deceptive wooden hut. Once to the bottom, the structure is all at the same floor level.

A technical room is accessible besides the entrance, with a power generator and electric cabinets for managing power supply in the bunker. The major components in the system, still working, are made by Hägglunds, a major mechanical brand in Sweden (also making the highly successful Bandvagn 206 tracked trailer vehicle, still in use today).

Then you get access to the main hall of the bunker, with a somewhat informal appearance, dominated by armchairs and low tables, and with a kitchenette in a corner. Everything is original and clearly dating from the Cold War era in terms of style.

From this gathering and relaxation point in the bunker, it is possible to reach immediately four relevant functional rooms. The first, and likely the most distinctive, is the situation room, which is visible also from the hall through a large transparent glass window.

To the far end from the entrance is an elevated console desk, with signal receivers, telephones and keyboards.

The room is basically built around a tactical table, with a map of the area pertaining to the SOC, where the information gathered by the LS reporting to this station could be represented graphically. The table you see is possibly the only reconstructed part of the bunker. Over the years, with the technological developments described above taking place (especially in STRIL 60), this table was updated with some degree of automation in the representation of information. The original piece in place when the bunker was decommissioned was taken away at some point, and a careful reconstruction of an analog table has been employed to give a lively idea of the appearance of the situation room in a time when information was managed manually. Furthermore, a regional map and a situation board are visible close to the entrance.

The location was manned by staff of the Optical Air Guard, traditionally women since the WWII era. These were regimented non-military voluntary staff, whereas the commanding officer of the center was from the military. He usually stayed in a second room reachable from the bunker hall, and overseeing the situation room through a smaller glass window.

In that room, his desk has been preserved in a mint condition, with a typewriter, and even military kits with pens and pencils. Close by is a more recent computer console, with a cryptography device.

A very interesting component of the visit is a number of original manuals and publications scattered around the bunker. Among them are aircraft recognition manuals, reporting the silhouette of known aircraft from all nations, and the corresponding relevant performance. These original manuals offer an interesting cutaway of the air force arsenals on both sides of the Iron Curtain, and their evolution over the years.

Another core technical room reachable from the hall is dedicated to signal gathering and management. The appearance here is mostly from the higher-technology phases of STRIL 60 and the OPUS system. Among the most distinctive features are the cabinets with the electronic boards from the era, which allowed for the management of the data coming from the peripheral station of the network, including for filtering, visualization on the situation table, and forwarding to the LFC.

The original devices once employed by staff on top of the LS towers are on display here – two portable consoles, one for vocal communication, and another special console for allowing the controller to specify data of the observation target, including its course. The original battery pack is still in place, with labeling from the time.

Interestingly, some of the older optical gear is actually from Hitler’s Germany, marked with the Eagle of the Third Reich.

Vocal communication lines allowed inbound traffic, as well as broadcasting capability, which could be directed also to the local population in case of an incoming attack, also employing recorded messages.

The fourth technical room accessible from the hall is was for air pumping and filtering. Despite not intended for survival of a numerous staff over a long time span, the bunker had an air filtering capability, as typical from the WWII and early Cold War era, when the bunker was built. Today, this system helps in keeping the place ventilated and fighting humidity. Manual pumps from the time are in place, as well as original spare parts, from governmental supply.

Finally, a small sleeping room, reportedly seldom employed for the task, can be found with original berths.

Getting there and visiting

The site is not open to the public, and credit for allowing me and a friend of mine on this exceptional visit goes to the current manager of the place, Mr. Anders Sundberg, and to Mr. Erik Mårtensson, retired officer of the Armed Forces of Sweden, who arranged this visit. It is possible to visit the place by prior appointment only. Contact sightraider.com to establish contact with Mr. Sundberg, who speaks English and has a detailed knowledge of this site as well as of the entire defense system of Sweden since its origin. A visit is therefore warmly recommended for a first-hand experience of an original site within the defense network, and for learning about it from its knowledgeable manager.

Missile Museum, Arboga

The Arboga Robotmuseum, mostly dedicated to missiles, engines and air defense systems of Sweden, can be found in the town of Arboga, roughly 90 miles west of Stockholm.

The town has a long tradition in warfare development, an heritage which is still lively represented by the presence of the Armed Forces and of companies operating in the field of intelligence and warfare systems, including a branch of SAAB. Their quarters are to the south of the town, where an old airbase can be found, with a one-of-a-kind bunker in the side of a local hill, dating from the 1940s. Today employed as a warehouse and barely visible from the northern fence of the airport, this bunker-hangar was designed for missile-related study and development, witnessing a significant commitment of the Swedish government towards that field of research, and towards the town Arboga as a strategic location, already back in a time when rocketry was in its infancy.

The museum is geographically close to the city center. Besides being supported by the Government within the official network of museums dedicated to the heritage of the Armed Forces in Sweden, it is run by a dedicated group of enthusiasts, mostly former military staff or knowledgeable technicians, which give an especially lively atmosphere to the place.

The display starts with a collection of items retracing the history of rocketry in Sweden. Curiously enough, a rare original V-1 from Hitler’s Germany dominates the display by the entrance! Similar to other locations in northern Poland and the Danish island of Bornholm (see here), territories geographically north of the Third Reich’s experimental laboratory of Peenemunde (see this chapter), and within range of the V-1 and V-2 early self-piloted flying weapons, were crash-landing places for experimental flights gone out of control. Southern Sweden was no exception. Moreover, the one you can see in Arboga is the only well-preserved V-1 landed in Sweden. The good state of conservation is evident looking at the fuselage and engine casing.

Even the onboard systems are almost perfectly in shape, including the knob to set the target distance covered by the flying bomb (measured approximately, by recording the rotations of the small ram propeller to the front). Also the actuators for the movable tail surfaces can be seen. They were fed from two tanks of compressed air, one of them, sectioned, revealing the fabric-inspired construction.

Most interestingly, the pulse-jet core, with the injection pipes and the radially oriented valve system, is also displayed.

For many nations including Sweden, the analysis of the – for the time – very advanced aeronautical projects of the Third Reich constituted a valuable starting point for their own development programs in the field. The topic is relevant to the museum in Arboga, where many early designs of autonomous flying platforms developed in Sweden are represented. Notably, an early project from the Navy, the RB310 on display, from soon after WWII, was pushed by the the same motor type as the German V-1 (note the distinctive side inlets).

Yet until the late 1950s the pulse-jet concept lived on with the RB315 ‘Agaton’, where the air breathing component of a developed version of a pulse-jet (the SM11, not dissimilar at a glance from the original German design) can be seen emerging on the fuselage.

Still air-breathing yet based on small turbojets, two interesting designs from the same era are on display. One is the compact long-range anti-shipping RB15F, developed for the SAAB AJ37 Viggen, and employed as well with the JAS39 Gripen. The other is the target drone developed by Beechcraft in the US as MQM-107, and in service in Sweden as the RB06. Its own small French-made TRI 60 turbojet can be seen below the the aircraft.

Perhaps the most massive among those on display is the ship-mounted version of the RB08A. This design was operationally employed within the Navy (see here), and later for coastal defense employing land-based batteries. It was pushed by a small turbojet by the French company Turbomeca. This heavy radar-homing anti-shipping missile is displayed with some of its 1960s-fashion internal systems dismounted.

A full array of missiles employed by Sweden’s Armed Forces yet originally designed in NATO Countries is on display, along with a number of prototypes and models originally from Sweden.

A less-known chapter well covered here is that of special under-wing pods. For example, the BOY401 flare dispenser for the Gripen reveals a massive sized and non-trivial construction, when checked from a close distance. Even more complex is the BOX3 pod, originally designed in the 1960s for the SAAB J32 Lansen as a decoy dispenser for detection jamming, with provision for flare and even a nose-mounted radar.

Active jammers are represented for example by the Apparat 27 and the U22 capsule, on display side by side, ahead of the fuselage piece and engine from a SAAB J37 Viggen.

A second area of the museum is dedicated to diverse smaller-scale ground-launcher missiles, as well as drones. For example, the very successful RB53 Bantam and RB56 ground-launched anti-tank missiles are on display, with the corresponding aiming device and computer. The bigger RBS17, the Swedish version of the AGM-114 Hellfire, has been placed side by side with others, allowing for a direct size comparison. It is in service with the coastal defense artillery.

An interesting cutaway is offered for the case of the RBS90 surface-to-air missile, revealing the complexity within the casing of this type of weapon. Nearby are two unmanned flying platforms employed by Sweden’s Armed Forces, the French-imported UAV01 and the lighter Swedish design of the UAV02 with its own control console. Sweden employed a SAM systems for protection of strategic sites, like airbases. Notably, the massive British-design Bloodhound missile was employed (one can be seen outside the museum). A detailed scale reproduction of a a SAM battery cand be found here as well.

Cameras, flash lights, pods employed for PHOTINT/SIGINT, and a radar head from the nose cone of a J37 Viggen attack aircraft are on display as well.

Notably, some of the gentlemen behind this collection were deeply involved in the airspace monitoring and defense activities of Sweden (see also the previous site on this page) during their military careers. Their experience with the STRIL initiatives is a fundamental knowledge base in this respect, and a chat with them is warmly suggested for everybody with an interest in this chapter of warfare history. Some of the radar consoles to be found in the top-level nodes of the air defense network (LFC), where all data from peripheral nodes were assembled to represent the detailed situation of the air space, are on display in the collection. They allow the visitor to retrace the technical evolution of the radar technology for air defence.

Notably, since the arrival of the SAAB J35 Draken, it was possible to send the data of an intruder to the panel of the aircraft via datalink from the console of the radar system (in particular the Decca PS-08 radar, of which four covered the exposed territory of Sweden, was an enabler in getting sufficiently accurate data). The console is on display together with the panel of the Draken. A supersonic single-pilot aircraft with exceptional performance, that aircraft was not easy to pilot with a fully analog cockpit. The addition of information on another aircraft, theoretically very effective for managing an intercept, in an operative scenario required a very high skill and preparation by the pilot, to face a very high workload.

The general amelioration of electronics over the years allowed to develop these systems, in conjunction with the appearance on the scene of the SAAB J37 Viggen and later the JAS39 Gripen, greatly reducing the workload of the pilot by displaying target information on scopes or maps, making them more promptly usable.

A mainstay of the defense system, radar consoles allowed controllers to keep the entire airspace of Sweden under watch. During the Cold War, the range of these systems allowed to scan well south of Berlin and within the USSR. However, the vantage geographical position of Sweden on the boundary of the Eastern Bloc put this Nation at risk of intrusion. For safety, in the mutual mistrust among opponents typical to the Cold War, camera recorders were employed since the 1960s to keep trace of radar blips, also to the aim of proofing intrusions or violations. The special camera arrangement on top of a radar scope is on display as well.

These recordings are now a valuable and interesting trace from the past, witnessing momentous events like the withdrawal of Soviet forces following the 1968 Soviet invasion of Czechoslovakia and the (sad) conclusion of the crisis, large exercises of the Warsaw Pact forces over the Baltic, or little-known, evident intrusions of Soviet aircraft over Swedish territory, and even the overflight by a USAF Lockheed SR-71, at its typical, extremely speed. This incredible material, visible in the museum in the form of a cyclically-running documentary, can be purchased as well after visiting.

A big component of the museum is dedicated to a large and neat collection of aircraft engines. The aircraft design program of Sweden, based on the SAAB designs from the late 1940s until the end of the Cold War, was supported by jet engines modified mostly by Volvo, starting from British or American designs.

The presentation in the museum allows to learn much about the specific features of many of these aircraft engines, by displaying cutouts, technical drawings, as  well as components of the ancillary systems and utilities (pumps, generators, etc.). Interestingly, a poster-size reproduction of an old picture portrays the local bunker hangar in Arboga (see above).

An interesting display of cockpit panels from Swedish aircraft allows for an analysis of the evolution of their design. An old flight simulator for training purposes, the ubiquitous US-designed Link Trainer, was apparently employed also in Sweden.

Finally, another exceptional feature of this museum is the availability of two simulators of the SAAB Draken and Viggen! These have been prepared making use of sections of their respective fuselages, notably including the cockpit. They make for an unmissable experience for everybody, especially if you already have some piloting experience – in that case, you may have chance to fly one of these two iconic attack aircraft from the Cold War with incredible realism, for example on an intercept mission versus a Soviet cargo, guided by the expert words of an authentic radar controller!

Getting there and visiting

This one-of-a-kind museum on a very interesting and special topic makes for a must-see destination for everybody with an interest in the Cold War. The exact address of the museum is Glasbruksgatan 1, 73231 Arboga. The location has a large parking ahead of the entrance. The premises taken by the collection, on the ground floor of an old industrial building, are compact and easy to tour. Yet the collection is very rich, and a visit interacting with the group of friendly volunteers (some of them speaking English fluently) running the site might easily take  2 hours or more for an interested subject.

Additionally, an experience on the flight simulator is definitely worth a visit on its own. This can be arranged by prior email or call, and combined with the visit. The professional website, with full information on the museum and exhibits in multiple languages, can be found here.

My own exceptional experience on this site together with a friend of mine, which included memorable flights in both Draken and Gripen simulators, was kindly sponsored and arranged jointly by the Volunteers of the Arboga Robotomuseum, in particular Mr. Antero Timofejeff, and by Mr. Erik Mårtensson, both former officers of Sweden’s Armed Forces. To these gentlemen and to the Volunteers go my personal thanks and congratulations!

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.

The history of the underground installation in Kossa-Söllichau begins in the 1930s under Hitler’s rule.

In 1935, an affiliated company of the German chemicals giant WASAG, named Deutsche Sprengchemie Moschwig and devoted to the mass production of explosives for warfare use, had a new plant built in the rather uninhabited forest area between Leipzig and Wittenberg.

The plant, codenamed ‘Beech’ (or ‘Buche’ in German), was updated over the years and turned into a major production center for several models of shells and high-explosive charges. A primary contractor of the German Army, the company also held relevant patents, including one for hollow charge grenades.

By the end of WWII in April 1945, when the area fell under Soviet control and production was halted, the plant counted 3.600 employees, and had a production capacity of around 600.000 ammunitions per month. It had been provided with a dedicated road and railway connection, and built mostly underground, with several concrete bunkers surfacing from the grassy terrain around.

Following the Potsdam agreement (July 1945), the area was completely flattened by the hand of the Soviets, similar to some other production facilities in Germany. Demolition had been completed by the end of 1947. Following that, the area remained silent for more than a decade.

By the early 1960s, with the Cold War and rearmament in full swing, the the Nationale Volksarmee, or NVA – the short name of the Armed Forces of the GDR – had been long established as an ally of the Red Army. The latter was physically present in Germany with a huge number of troops and war material, having taken over many of the former German bases from WWII (see here or here for instance). However, the GDR clearly had its own Armed Forces, which actually could count on high-quality war material, typically either manufactured in Germany or supplied by the USSR. More and more locations – especially the most secluded and easy to hide – got surrounded by fences, and ended under the control of the NVA for many different purposes.

Deployed on the border with the West, and considered a reliable and well-trained partner by the Red Army, the NVA was included in the war plans conceived in Moscow, intended to unfold in the event of an open war with the neighbor NATO Countries. The NVA had two larger military districts, south of Berlin (III) and north of Berlin (V). In case of war, district III would give birth to a 3rd Army of mixed GDR/USSR forces, to quickly push towards the south-west into Federal Germany (heading to Koblenz), and from there to the Atlantic coast, to be reached in a matter of a few days.

The headquarter of the 3rd Army was in the so-called ‘Mosel’ bunker, an underground command facility near the town of Zwickau, today converted for an alternate use and not visible at all.

An alternate control site, which was also primarily involved in drills and training, was built in the area of the former ‘Beech’ installation, and took the name of ‘Bunkeranlage’ (i.e. bunker installation) Kossa-Söllichau. This site was prepared in the years 1976-79, and consisted mainly of 5 large interred bunkers on the same premises, capable of resisting to tactical nuclear blasts, with up-to-date systems for communication, and an ability to replicate war situations, so as to carry out realistic and complicated tactical simulations and drills. The staff was typically of 400.

Similar to the majority of military assets in Germany – and especially within the super-militarized ex-GDR – Kossa was incorporated in the Armed Forces of reunified Germany (1990), but was soon declared surplus, deactivated and handed over for civilian use.

A society of enthusiasts is today running this former facility, keeping it open for visitors on a regular basis. What makes Kossa an exceptional destination for both the general public and the most committed war tourist as well is the great state of conservation of the entire facility. As it can be seen in the following photographs, taken in Summer 2022, inside the bunkers it is possible to see not only the original structure, but most of the original communication systems, paneling, signs, furniture, lamps, toilets, lighting, wallpaper, etc. making the place a very vivid testimony of the Cold War years.

All in all, this is one of the best surviving specimens of bunkerized NVA sites, and definitely worth a visit for a rich in detail full immersion in the military technology and history of the Cold War years.

Sights

A visit to the Kossa site will start walking past the original inner gateway to the bunkerized part of the complex. The original wall going all around the entire military area has been partly removed, allowing to get direct access to the ‘core’ of the installation by car. Traces of the electrified fence running all around this inner part of the complex are still standing. The entrance to a bunker for the guards can be seen in this area, but this cannot be visited.

The core of the complex with the military bunkers is aligned along a single, mostly straight technical road, built with large concrete slabs. The road track today is the same as in the original pre-WWII complex, and for this reason, it was not camouflaged. Other buildings in the complex, an even the connection roads departing from the main one, are painted in camo coat, for deception in case of overflight by plane or satellite.

The ticket office today is hosted in a large technical building by the entrance. In this area there used to be canteens and other services.

Past the entrance to the bunker area, it is possible to visit five bunkers, which will be listed next.

Computer Bunker

Four out of five bunkers (the exception being the intelligence bunker, see later) are built around the same blueprint. They have a single entrance door, deceived under a small wooden hut. Access to the bunker is via a security and decontamination path. At first you see a big camera at the level of your face, and an intercom panel, all for identification. Next follows a sequence of tight doors, at a close distance from one another, producing three small tight compartments.

In case of nuclear/chemical contamination, faced in wartime, in the first compartment you could take an anti-poison kit, EP-68. Exemplars of this are still in place. In the next compartment you had to throw away all your clothes and belongings, which were put through a hatch to the side. In a third small compartment, you found a shower – a central passage in the decontamination process, even in case of exposition to nuclear events.

Through a last tight door, you could finally enter the clean area of the bunker. Here regular toilets and showers can be found, before going down one level, to the technical part.

Back then, there used to be three levels of air sealing. No air sealing, in regular, no-war/no-drill conditions, meant the decontamination procedure was not activated, and the bunker was ventilated with fresh air. In sealing conditions, typically at war but not under direct attack, the bunker was tight closed, and air was pumped from the outside through huge filtering canisters, purpose designed to stop both smoke and other gases, or poisonous chemicals. On the third level of air sealing, corresponding to an emergency condition (e.g. a direct attack), no air was pumped from the outside, and special filters capturing carbon dioxide allowed to carry on for a limited amount of time – reportedly a shorter time than granted by food or water storage.

Filters for the air conditioning system (sealing level 2) and for adsorbing carbon dioxide (sealing level 3) were made in the USSR. Those for carbon dioxide are scattered around the bunkers, and feature a rather vintage Soviet look, with a prominent five pointed star on top. The label carry the assembly year, in most cases the early 1970s.

Once downstairs, you can appreciate the construction of the bunker lower level, based on prefabricated concrete frames. The bunkers in Kossa were capable of resisting blasts typically from smaller tactical devices, and were ranked at the fifth strength level (level ‘E’), the first level being the strongest.

Here a few rooms are still perfectly preserved with computers, of which the most impressive is a mainframe AP-3, working with magnetic tape. The GDR could boast a top-notch electronic industry within the Eastern Bloc, and all consoles and electronics in Kossa bear local labels.

The purpose of the computers, deemed so relevant to create a bunker specifically for them, was the fast elaboration of all information from the war theater. The latter was both local and global, since thanks to the links reaching the site through the intelligence bunker (see later), information of any kind could be elaborated, allowing the constant updating of operation maps, and the monitoring of all war assets. In drills, the computation capacity of the the system allowed to simulate events, thus forming the core of war-game operations.

A small part of the same bunker, a kind of mezzanine, was designed as a small hospital – all exhibits are original here as well.

More items on display in this area include original dosimeters and gear for checking radiation levels – either GDR- or USSR-made. In the connecting corridors are an intercom and an alarm horn – just examples of the perfectly preserved material on display.

Command Bunker

The command bunker shares the general arrangement with the computer bunker. A full anti-chemical/biological warfare suit is displayed by the entrance, ahead of the decontamination facilities. This type of suit should be worn over regular garments, and made for a very uncomfortable, ultra-warm and suffocating top layer, which reportedly caused extreme sweating.

The focus here is a control room, with a large table and an operation map, as well as connections through several lines to the relevant information networks. On one side of the control room are desks for telephone operators. On another, watches and chronographs. Also interesting are two TV-scopes, which allowed to plot useful information especially in case of drills.

Examples of maps for military drills are scattered all around. Since war plans were all variations on the same theme – a quick attack pushing to the west – all corresponding maps feature this type of planned motion, from within the borders of the GDR to the FRG. The name of the drills can be seen clearly stated on the maps – for instance ‘Grenzschicht – 81’ from 1981.

Other rooms on the underground level feature very interesting examples of machinery for translating information to/from paper maps, even physical 3D maps with elevation!

Satellite or spy-plane images of the site are on display as well. The site of Kossa was reportedly not far from the southernmost of the three air corridors reaching West-Berlin from the FRG. However, even though the site was not unknown in the West, its purpose remained largely a guess for the duration of the Cold War – and likely so also for the local civilian population.

Technical Bunker

A major concern in the Cold War was that of the survival of the chain of command in the event of a total nuclear war. This led to the implementation of additional on-site plants, for self-sustained operations in case a nuclear explosion nearby made the area unsuitable for human life, or when links with the surroundings were lost. These plants included primarily power generators, typically large Diesel engines with their fuel tanks, and drinkable water tanks. As seen in the computer bunker, also breathable air was a major concern.

In the technical bunker in Kossa, similar in shape to the previous two, at least two large power generators can still be seen – and smelt… – on the underground level. Several electric parts for replacement are also there. Another room hosts large drinkable water tanks.

An interesting preserved office for a commanding officer still retains its original GDR wallpaper, and additional comfort is provided by a fake wood pavement.

Large electric cabinets take a big room, where instrumentation for radiation measurement is on display nearby.

Other particulars include a dial telephone with a reminder of the quick reaction numbers, including the Volkspolizei – the name of the People’s Police of the GDR, which can be seen on a label!

Intelligence Bunker

The intelligence bunker is way larger than the others in Kossa, and is also more articulated. Access was possible via two bulky metal gates, located at an underground level on the far ends of the bunker, and reached through truck-sized ramps from ground level.

Behind the door, a tunnel of prefabricated concrete allowed to store many vehicles – typically trucks, jeeps and trailers, including vehicles with communication functions.

To the interred back of the tunnel, a human sized hatch gave access to the pressurized, tight area of the bunker. This inner area, completely interred, is surrounded by a concrete case, built by a single pouring to avoid the creation of weak junctions, and such to withstand intense blasts.

Following a tight compartment, with an array of original air-filtering canisters on display, you get access to a long corridor, providing access to some rooms with technical gears for communication. Here communication with different levels of secrecy were managed, accessing all the existing links implemented in the years of construction within the GDR, and between all Countries of the Warsaw Pact and the USSR.

A first room is centered on a large console, with an original teleprinting device still in place – top-notch for the time. Still in use today in some businesses, teleprinting is a very reliable way of communicating, which is also less prone to interception than telephone.

An adjoining room managed contact with three wired systems of communication, working at increasing levels of encryption security, and used for transmitting routine or less-standard orders. These systems included S1 and SAS communication protocols. The corresponding transmitters/receivers – now very rare pieces of machinery – can be seen on display.

Encrypted incoming messages were sent to a special room, where they were translated in human language, before being internally forwarded to the command bunker. Similarly, encryption facilities were all in another room, where outbound communications were made ready for transmission.

An impressive technical room is stacked with communication electronics. The number of components is really high, and reflects a very high performance, achieved by means of top level, but relatively bulky, components from the 1970s.

A room in this bunker is dedicated to the ‘BARS’ system (‘БАРС’ in Russian), a troposphere (i.e. not wired) transmission system within all States in the Warsaw Pact and with the USSR. Beside an indigenous transmission protocol, the system made use of purpose-designed antennas, with easily deployable nodes put on wheeled trucks. An evoking, very interesting map of the fixed nodes of the system, in Russian, can still be seen on a wall. The desks for the operators of the system are just besides.

Another interesting item is the control panel of a micro-wave antenna, installed in Kossa at a shallow underground level, in an area which can still be located, corresponding to an inexplicable grassy lot along the main road in the site. This antenna system was apparently never used, on grounds of energy consumption and potential damages to other systems in the Kossa site.

Back outside, close to the intelligence bunker are an original weather station, placed nearby a radiation detection system – looking like a bell bolted to the ground. Examples of connection roads covered in camo paint can be seen in this area. Along the main road of the site, many ramps give access to semi-interred lots, where technical trucks used to be placed for operations.

An example of these trucks is a Soviet trailer for enemy signal jamming. This is well preserved both inside and outside. The label tells the construction year – 1986.

Museum Bunker

The last visitable bunker is similar in shape to the former three, and has been converted into a collection of items from the history of the old WASAG site, the NVA bunker and the Cold War.

Propaganda items from the GDR enrich this interesting collection, as well as rare photographs from the totally gone ‘Beech’ site originally developed in the Third Reich years. Also on display are detailed designs of the weapons produced here in WWII.

Getting there and Visiting

The Kossa installation can be easily reached by car, roughly 20 miles south of Wittenberg and 30 miles northeast of Leipzig. Exact location here.

The Kossa bunker is professionally managed by a dedicated Society. Their website is here. They speak only German, and the website is in German accordingly. Opening times are published for the season, and are basically in all weekends in the warm season. A synthetic leaflet in English can be obtained. However, the basic notions on this page may also help in getting much of the visit.

Two separate tickets can be purchased, one for a self-guided visit of the computer, technical and museum bunkers, and another for a guided visit of the command and intelligence bunkers. The guided tour is offered only once per day in German, in the early afternoon as of 2022.

A good strategy for a complete visit may be checking in during the morning, visiting the self-guided part, having a packed lunch, and taking the guided tour.

I followed that plan. This meant a stay of roughly five hours. The report on this page was obtained visiting the site together with Dr. Reiner Helling, who offered me a very detailed insight of the Kossa site, before we took the guided tour.

Photography is allowed everywhere. Flash/tripod generally not needed, at least with high-ISO sensors.

Possibly only cash accepted at the ticket counter.

The New Life of a Soviet Base in Germany – Ribnitz-Damgarten

Most Soviet bases in the former territory of the German Democratic Republic met with oblivion following the departure of their Red Army tenants back to mainland Russia, in the early 1990s.

Most locations – including full scale airbases (see here, here or here), infantry academies and shooting ranges (see here) and nuclear warhead bunkers (see here) – have been returned to nature, demolished or converted into something else. Much on this website documents this hidden part of the Cold War heritage in Germany.

However, there exist exceptions, like the airbase of Grossenhain with its preserved Granit-type bunker (see here), or the central Soviet headquarters of Wünsdorf (see here).

Another notable exception is that of the former Third Reich, and later Soviet, airbase of Ribnitz-Damgarten. Following an exploration in a day of closure in 2016 (documented here), the site was visited again legit, this time accessing the unique Museum of Technology of Pütnitz. The museum collection is very nice in itself, covering both civil and military vehicles from the DDR age, as well as heavy Soviet military vehicles, and even a few boats and aircraft from the Eastern bloc.

The museum is hosted in a complex of hangars dating from the years of the Third Reich, when the airbase of Ribnitz was active for experimenting with seaplanes, and busy with a facility of the Heinkel aircraft manufacturing company. These concrete hangars are still standing today, undoubtedly an example of German engineering excellence.

The Soviets made good use of this facility, and Ribnitz-Damgarten became a very active base on the Baltic coast for the full span of the Cold War – until the withdrawal of the then-Russian troops, who used this airport as the springboard for their final hop to their new home in Russia.

A further reason to pay a visit to Ribnitz-Damgarten is the chance to assist to the one-of-a-kind reunion and live exhibition of preserved vehicles from the Soviet bloc. Held in the summer, this ‘Treffen’ (i.e. reunion) is really worth the effort of setting up a trip, even when visiting from abroad. It is a multi-day event, and possibly the largest meeting of aficionados of cars, motorcycles and trucks from the communist world, with the chance to see all this good old technology at work, i.e. spitting and thick-smoking, all around the base. Chance is that you will drive on the original Soviet runway to reach the event parking!

Besides this yearly event, the museum offers live demonstrations of military vehicles on a more regular schedule.

The present post and photographs cover a visit to the Technology Museum of Pütnitz in occasion of the reunion of Eastern Europe vehicles held in late August 2021.

Sights

Museum of Technology of Pütnitz

The museum of Pütnitz has taken over the hangars of the old Third Reich base to the west of the airfield of Ribnitz-Damgarten. These hangars are pretty interesting from an architectural standpoint. By using large and curved concrete frames, the inside volume is extremely big for the time. As a matter of fact, they were kept in use for decades, since they could match the size of larger aircraft and vehicles of the Cold War.

These hangars are just a handful, but complemented by smaller (regular size…) hangars they provide for a very large display area, wisely adopted by the museum for its exhibits.

One of the hangars is dedicated to the NVA, i.e. of the Armed Forces of the former GDR. Among the many artifacts on display, are a MiG-21 fighter, the skeleton of an Antonov An-2 transport, and a Mil-8 helicopter. The latter has been placed in a suspended position, with a mechanism to rotate its rotors!

In the same hangar you can find a pretty extensive collection of light armored vehicles, technical amphibious vehicles as well as full-scale tanks formerly in use with the NVA in different stages of the Cold War.

A smaller area is dedicated to a display of NVA uniforms, GDR emblems and medals, uniforms of youth organizations within the GDR, as well as detailed scale models of war material in the arsenal of the USSR or the GDR over the years.

A second smaller hangar hosts trucks of Soviet make, formerly used by – presumably – the NVA. Some are especially interesting, since they were used as missile transports, and are on display with their original trailers and… payload! Also trucks transporting Soviet-made radar antennas, for air target capture or anti-aircraft missile guidance, are on display.

To the back of the same hangar, a super-interesting collection of material connected with nuclear warfare is on display. In particular, field instrumentation for measuring radiation levels, dosimeters, anti-radiation suits and masks, specific medical kits are part of this rich and uncommon exhibition.

Some of the measurement equipment is still working, with old-fashioned, low-light electronic displays still lit – really an evoking sight from the Cold War era!

Yet in another hangar, a huge collection of GDR cars and motorcycles is on display. Most of these now vintage cars and vehicles used to be a rather common sight in the GDR. The now iconic Trabant was a product of the GDR. However, many other car manufacturers existed in the Eastern Bloc, and in the USSR as well, and their products were often exported to other Countries in the bloc.

Stately cars for the top-ranking communist leadership were usually Soviet-made. You can find a small gallery of these Cold War icons in a corner of the same hangar, ahead of giant portraits of the SED (the ruling party of the GDR) leaders – Ulbricht, Honecker, Krenz.

To the back of the hangar, classic motorcycles from the Eastern Bloc are on display. They include MZ motorcycles in use with the Völkspolizei, the police of the GDR. A sizable collection of cameras is also on display.

In the same hangar are a reconstruction of a gas station, as well as a crop-dusting propeller aircraft.

Notably, you can spot fading writings in Russian on the walls of this hangar, an heritage of the Soviet tenancy of the airbase.

Some museum items are on display outside. Some of the military vehicles in the collection are still in working conditions. Live demonstrations of tanks and armored transports are regularly planned, and make for a nice sight and a thrilling experience!

Soviet Relics

Despite having being taken over by the museum and other commercial activities, the premises of the old Soviet airbase of Ribnitz-Damgarten betray the long decades of Soviet use. Besides the relics you can find scattered around in the airfield (see here for a previous exploration), very close to the museum hangars you can spot several technical buildings belonging to the base, and now basically abandoned.

On the side facade of one of those, a colossal Soviet emblem can still be seen, albeit now fading.

Signs written in Russian can be spotted here and there, as well as an original, very interesting full scheme of the base (in Russian too), a typical sight in any Soviet base.

Now-rotting buildings for the base staff can be found emerging from the overgrown vegetation to the north of the hangars.

Finally, the runway is still in a good shape, albeit cut to the east to make room to yet another solar power plant – with a really questionable function, considering the rainy weather physiologically insisting on the region most of the year. The original centerline and other markings can be clearly seen still today.

The airport is closed, but since the runway has not been taken away, perhaps some hope remains for a future with at least general aviation activities, like in Rechlin or Finow.

International Reunion of Vehicles of the Eastern Bloc

Perhaps among the busiest days of the museum in Pütnitz, those of the ‘Internationales Ostblock-Fahrzeugtreffen’ (which translates into the title of this paragraph) make for one of the most exciting occasions for a visit. Usually taking three days, this colossal reunion hosts roughly 2.000 vehicles, from cars to trucks, from farm tractors to motorcycles, from side-cars to firefighting vehicles, and from 4×4 military transports to camping trailers – all made on the communist side of the Iron Curtain!

The reunion is international, and many come from beyond the near border with Poland. In 2021 the reunion hit its 20th edition.

All vehicles are parked in virtually any lot of flat land between and around the hangars of the museum, including the original taxiways and any grassy areas around.

Furthermore, besides some official movements and parade, you will see vehicles moving around at any time, with their very characteristic good old piston engine crackling sound, as well as much spitting and thick-smoking!

Besides the countless Trabants, built in several different versions you will come to discover, chance is to see massive Soviet GAZ military trucks, or even Hungary-built Ikarus buses!

The ‘Treffen’ of 2021 was especially unlucky with the weather, which on the plus side allowed many vehicles to show their all-weather capability!

To better appreciate the noise and smoke, have a look to these three videos!

Visiting

The Museum of Technology in Pütnitz allows you to access the otherwise inaccessible base of Ribnitz-Damgarten. Access is recommended by car. The entrance is to the northeast of the airfield, through the original gate of the airbase. The museum has a website here.

Visiting in normal conditions, i.e. out of any special event, may take about 1 hour, more for a piston-power-minded subject, or for military/vehicles enthusiasts. In occasion of the vehicle reunion, planning a half-day visit at least is recommended, since the display of vehicles is really huge and worth a careful glance. A talk with many nice owners and enthusiasts may be a further plus in this occasion.

Soviet and East German Relics North of Berlin

For the full span of the Cold War, the communist German Democratic Republic has been a highly militarized region.

Due to its position right on the European border between NATO countries and the USSR-led eastern bloc, this relatively small state was kept in high consideration by the Soviet military staff in Moscow. In the re-organization of Soviet forces following the end of the Great Patriotic War (i.e. WWII), of the four Soviet groups of forces stationed in all satellite countries outside the Soviet border, one was specifically named ‘Group of Soviet Forces in Germany’. This group was headquartered in Wünsdorf, the former location of the German OKW south of Berlin (see this post), and had under its command a force of some hundred thousands troops, divided in two tank armies, an entire air army, three mixed armies and a supplementary artillery division. Supplies were in no shortage either, with some tens of fully operational airbases/tank polygons, academies and housing for all the troops and respective families.

Despite the very significant Soviet presence, the GDR invested a huge capital of its own in the development of a full-scale military strength. The East-German National People’s Army (NVA) received top-tier technology from the USSR, and did of course manufacture military supply of all sorts. Sustaining this army, together with the enormous para-military organization of the internal Ministry of Security – the ill-famed STASI – and other governmental organizations, military expenses undoubtedly contributed to the economical crisis hitting the GDR in the 1980s, setting the scene for its final demise.

The region north of Berlin was particularly rich in military and governmental installations, some of them highly classified, their history shrouded into mystery. You can find some information in dedicated posts on this website (see this post, also here and here).

In this chapter, some more items of interest are featured. Four of them are abandoned tokens from Soviet occupation. A nice belle-epoque villa on the shore of the Röblingsee in Fürstenberg, where the headquarters of the 2nd Guard Tank Army was headquartered since Stalin’s era to the withdrawal of Soviet forces in the 1990s, is the first of them. The second is a unique, forgotten Soviet monument, to be found less than two miles south of Fürstenberg. Two more are memorials and cemeteries, for Soviet troops who perished in the last stage of the Great Patriotic War (WWII) around Berlin.

Other three points of interest are instead GDR-related. The first is the former academy for future leaders of the communist party, established in Wandlitz in the years of Stalin, and initially led by Erich Honecker, later to become the omnipotent leader of the GDR for two decades. In the same area north of Berlin – and precisely in Waldsiedlung, today a nice clinical campus in the countryside – are the former private houses of the members of the central committee of the communist party of the DDR – personalities like Walter Ulbricht, Erich Honecker, Erich Mielke and Egon Krenz lived here with their families. Finally, you will find a glimpse from the so-called ‘Honecker bunker’ in Prenden. This big and highly classified installation was prepared in case of war, to protect the leadership of the GDR and ensure safe communication with Moscow.

Photographs were taken in summer 2019 and 2021.

Soviet 2nd Guard Tank Army Headquarters, Fürstenberg/Havel

Among the Soviet forces permanently stationed in the GDR in case of war, there used to be two entire tank armies, the 1st and 2nd. The former was headquartered in Dresden, whereas the 2nd – named ‘Red Banner’ – in Fürstenberg/Havel.

The headquarter in Fürstenberg is basically an old villa, possibly dating to the late 19th century or a slightly more recent time. The villa is somewhat unusual in the panorama of todays Fürstenberg. This is a nice and lively touristic town, where many Berliners come to find a retreat in nature, less than 1 hour driving from home. Thanks to tourism-related activities, the area has got rid of the Soviet/East German grayness, and is now a typical village in the German countryside, graced with a creek and a small lake, where canoes and small boats are always roaming around.

In stark contrast with this, the villa is today completely abandoned, with overgrown vegetation almost hiding it from the main road. Access to the premises is easier from the back, where you first meet a typical Soviet prefabricated wall, and service buildings with evidence of a communist design – the usual yellow paint and railings on the windows with the stylized ‘radiant dawn of communist revolution’.

Getting closer to the house, you meet an access door, possibly going to a bunkerized area underneath. The house is in a really bad shape, with rotting walls, plants growing on the balconies and roof. The inside has been made completely inaccessible. A typical East German light is still hanging from the back wall.

To the front, a temple-like decoration contours the main door. It is difficult to say whether this decoration was there since the beginning, since it appears rather different in style from the rest of the villa.

A highlight of this site is the statue of Lenin still standing ahead of the front facade. The statue is in a relatively good shape. It looks like the man was portrayed during a discussion.

The concrete sculpture was accurately made, as witnessed by the facial expression and details in the embroidery of the tie.

On the front side, the villa used to be reachable with a large flight of steps climbing uphill, with Lenin on top. Today this perspective is gone, for vegetation has totally invaded the steps, and the front of the house is not visible from the street.

Getting there and moving around

The villa is located in central Fürstenberg on Steinförder Strasse (possibly) 44, on the southern side of the road. The house and its large garden estate are abandoned, but all other houses around are not. Getting closer without being spotted is easier from the backstreet. Technically speaking, the latter is accessible for residents only, so you may park somewhere else and come closer by foot. Visiting may take about 30 minutes with time for the pictures, for the house is not accessible inside.

It should be remarked that this site is probably not public, and at an unpredictable time it may be either restored or demolished – so checking it out may be not possible for long.

Soviet Monument, Fürstenberg/Havel

A rare example of Soviet commemoration monument can be found very close to Fürstenberg. Apart from the monumental sites in Berlin (see here), a number of smaller Soviet monuments are to be found around the GDR – impressive ghosts of a bygone era.

Among the best preserved are that in the former tank base of Zeithain (see this post), and this one in Fürstenberg.

The monument is composed of two parts, basically two concrete curtains facing each other on the sides of a small apron.

The smaller panel to the south is the most intriguing. It is apparently a celebration of an economic plan of the Soviet Union. It is all about the growth in production in several areas of industry and farming, likely resulting from careful planning by the top of the Soviet government.

Between a citation from Lenin and a stylized image of the Kremlin, several panels cite one by one the increases in production of anything from oil to weapons, from milk to corn.

To the back of the monument, the only remaining feature is a remarkable head of Lenin, with yet another citation. It is likely that other features have been removed by vandals, as empty frames can be seen aligned along this face of the monument.

The larger panel to the north is a celebration of the march to Berlin during the Great Patriotic War, likely related to specific actions of the Guard Tank Armies. The central slab features an image of the Soviet monument in Treptower Park, Berlin – one the most famous commemorative monuments in the Soviet Union, as witnessed by numerous images to be found still today in many museums in the former USSR (see for instance here).

Close by, reproductions of decorations and captions of what happened on some days of 1944 and 1945 are reported.

On the left panel you can see a reproduction of the march to Berlin, from the battlegrounds in the USSR, through central Europe and Germany. It is likely that some metal parts of the monument once used to connect the ‘points of interest’, but these have disappeared due to vandalism.

On the right wing of the monument the names of Heroes of the Soviet Union possibly from the Guard Tank Armies are cited one by one. Close by, the image of the ‘Soviet Motherland Calling’, pretty usual in Soviet war iconography, can be found together with other typical emblems.

Getting there and moving around

This monument is not maintained nor protected. It is open air, unfenced and freely accessible. It will be hopefully restored or moved to a museum, as the weather and vandals are taking their tolls. It can be reached along the road 96 about 1 mile south of Fürstenberg, immediately to the west of the road. A small unofficial parking area can be found ahead of it, making a quick visit really easy.

Soviet Memorial and Cemetery, Rathenow

The Soviet memorial in Rathenow is one of a number of smaller military cemeteries for Soviet troops in the region around Berlin. Soviet soldiers perished in the area in the thousands in the final stage of WWII (1945), when the Red Army entered the northeastern part of todays Germany from Poland, pushing towards Berlin and fighting against the agonizing but still fierce German Wehrmacht.

Apart from the gigantic and formal monuments in Berlin (see this chapter), more modest shrines are scattered around the German capital city, all built roughly in the same period, between the end of the war in Europe and 1950, in the years of Stalin.

The Rathenow site is a small town cemetery, a proportionate, down-scaled version of its larger counterparts in Berlin – especially Schönholzer Heide (see here) – and can be found in the center of the sleepy town of Rathenow. A central obelisk with a commemoration plaque is topped by a golden five-pointed star, the symbol of the Red Army.

A number of soberly designed grave stones for as many Soviet troops are aligned in rows, creating an elegant perspective. Most of the graves bear complete names, as well as the birth and death years. Similar to the war cemeteries dating also from WWI (see for instance here and here), the very young age of most of the troops in the final struggle around Berlin is readily apparent.

Despite being fenced and of course not left in a state of disrepair, the green areas immediately outside of the perimeter of the monument in Rathenow are somewhat neglected, perhaps reflecting a fading interest for this monument.

Getting there and moving around

The Soviet monument in Rathenow can be reached at the crossing of Ferdinand Lassalle Str. with Friedrich Ebert Ring, in central Rathenow. The monument is very compact and can be toured in a few minutes.

Soviet Memorial and Cemetery, Blumberg

The monument in Blumberg, in the northern outskirts of Berlin and really close to town, is smaller than the one in Rathenow (see above), but shares the general arrangement with it.

A central pillar with a commemoration slab is surmounted in this case by a statue of a Soviet soldier, holding a Red Banner flag.

Ahead and around the pillar, gravestones put flat on the ground are aligned in a perspective. However, the overgrown vegetation is basically hiding these lines of tombs, so that even from a small distance the central monument appears as an isolated item, put in the middle of a grassy area.

Actually, the major difference with other monuments of the kind lies in the rather remoteness of the one in Blumberg. It is a listed historical landmark, and therefore at least minimally cared for, but on the other hand, it is located relatively far from todays nearest settlement, hidden in the trees, and out of sight for anybody except people going there specifically for it. This makes it rather mysterious, a silent memento of old memories.

Getting there and moving around

The monument is conveniently located just out of the A10 highway (the external ring of Berlin), in the settlement of Ahrensfelde. You may reach Chausseedreieck and drive to its western dead end, where you can conveniently park. From there a grassy path points south into the trees, and in less than 150 yards you will find the monument. The size of the monument is small, hence no further walking is needed. A mosquito repellent is highly recommended in the warm season.

Free German Youth Academy & Joseph Goebbels Manor, Wandlitz

Deep in the countryside about 25 miles north of Berlin, about 3 miles from the small touristic village of Wandlitz, you can find a couple of highlights from the troublesome past of Germany, sitting side by side, close to the small Bogensee lake.

The first is the country estate of Joseph Goebbels, the famous minister for education and propaganda in the years of the Nazi dictatorship. This villa has been built in the war years, and often used by its owner, also for receiving guests. Goebbels obtained the estate as a birthday present from the Nazi Party.

Incredibly, the manor, built in a typical German country style, was not demolished after the war – so unlike other residences belonging to Hitler or his fellows, it is still there to see. It survived denazification, Soviet occupation and 40 years in the GDR as part of a school (see below).

The outside is the only part you can see. The appearance is sober, with simple lines and not much vertical elevation – it nicely integrates in the natural setting.

Access to the courtyard is from a small road, now part of the inner network of the larger complex surrounding the manor.

This complex is actually the other peculiar item you can find in Wandlitz. This enormous academy was built in 1951, on behalf of the Free German Youth (FDJ), a youth-training organization founded and originally run by Erich Honecker, later to become the general secretary of the communist party of the GDR in the 1970s and 1980s.

The academy was designed by Hermann Henselmann the same architect who designed Karl-Marx-Allee in the Soviet sector of Berlin – one of the most iconic ‘Stalin’s-style’ perspectives in the world. The complex is composed of two large opposing buildings, on the short sides of an internal courtyard. These hosted common areas, lecture rooms and a theater.

Along the longer sides of the courtyard are buildings with bedrooms and services for around 500 students.

The academy was for the future staff of the communist party, and in later years of the Cold War it was attended also by international students from communism-leaning nations, or sometimes even from NATO countries.

Following the collapse of the GDR, the building went on hosting educational institutions until the early 2000s, owned by the regional government. It was then mostly shut off, with some ancillary buildings still hosting institutions connected with the administration of the natural preserve around. It was put up for sale, for a while, but all potential customers failed to present satisfactory conversion plans. An expensive and inconvenient ghost from a forgotten era, as of 2019 its fate has not been sealed yet.

Today the place is not completely abandoned. Basic preservation works are being carried out, thus avoiding the roof to collapse or the walls to rotten. The names of the blocks are likely not from the GDR years. Similarly, a board with notices and maps dating from later than 1989 can still be seen, a witness of the post-GDR activity.

The garden is not growing totally wild, and some architectural addition must have been tried in a recent past – like a small modern fountain ahead of the common building to the southwest of the complex. The buildings are still supplied with electrical power – there are lit lights above some doors – and it is discretely guarded to avoid vandalism.

Getting there and moving around

Accessing the area is possible following the L29 from Wandlitz. About 1 mile from the village, the road changes its name to Wandlitzer Strasse. There is a local road with limited access taking to the east. You may park there, and proceed along the road by foot for about .5 miles to reach the heart of the complex. This is surrounded by private houses. There is no fence, but there are proximity sensors which trigger an inspection. I was reached by a warden on a car soon after my arrival. He spotted me, but did not come close, likely noticing I was just taking pictures outside.

The site is rather mysterious and well worth a quick visit for interested subjects. Touring the site will not take more than 45 minutes, taking all the pictures.

Private Homes of the Members of the Central Committee of the Communist Party of the GDR, Waldsiedlung

Similar to other top-ranking figures in the Soviet chain of command – like Stalin and others in his communist entourage, who did not spend much of their time in public or close to crowded places in central Moscow – the masters of the communist party in the GDR had their homes in the trees north of Berlin, relatively far from the city center and from the governmental buildings.

Actually, many of them lived together in a rather compact residential district, called Waldsiedlung. Access to the area was obviously controlled, but once inside the place was somewhat similar to a holiday settlement, with smaller single or two-family houses located along quiet alleys in a rural setting. The architecture is far from lavish – all houses are very similar to one another, and are designed in a plain typically East-German style from the post-WWII era.

Today, the settlement in Waldsiedlung has been converted into a campus for clinical studies. However, the original architecture of the place has been left mostly untouched, and explanatory panels telling quick information about the history of the residence have been planted ahead of most of the housing once occupied by old communist big brasses.

The office by the gate, and the metal gate itself, are totally original, as can be seen from historical pictures.

Among the first buildings past the gate is a former congress center/clubhouse/gathering facility for the inhabitants of the residence.

Moving on to the northern part of the settlement, the modest house of Erich Honecker and his wife Margot can be easily found. The two-storey construction has a patio on the backyard. A mystery wooden hut can be found next to the latter.

The Honeckers were forced to leave this house in the turmoil following the collapse of the wall and the starting of the reunification process. Honecker fled to the Soviet Union in seek for protection, quickly departing from the Soviet base in Sperenberg (see here). He was trialed in absentia, in connection to the order issued to the GDR border guards to used deadly force against people trying to pass the ‘anti-fascist wall’, and the ensuing deaths. He remained in the USSR until also that dictatorship collapsed, and he was forced to escape to South America, where he died soon after.

To the far end of the same alley is the house of Walter Ulbricht and his wife Lotte. Somewhat larger than Honecker’s house, it is however not much more evolved in adornments or architectural fantasy.

On another alley, parallel to the previous one, is also the house of Erich Mielke, the uncontested head of the ill-famed STASI, since its early years to the end.

The man was captured and trialed for an old case of homicide, after the shut-off of the STASI monstrous machine. He died soon after.

Today even these smaller buildings have been converted for a new function in the clinical campus. Therefore, they cannot be toured inside. However, strolling in this inconspicuous, quiet village where a huge concentration of power used to be seated, provides a strange feeling.

Getting there and moving around

The Brandenburg Clinic, which has now taken over the Waldsiedlung residence for the members of the GDR government, is on the road N.273, between Bernau and Wandlitz. The clinic in Waldsiedlung is rather busy, and the parking ahead of it may be crowded. However, since the place is guarded and access regulated, that is the only credible parking option also for a historically-themed visit. You can access the area by foot undisturbed, and take photographs of the exteriors. There are explanatory panels ahead of many of the former residential homes.

Honecker Bunker, Prenden

Geographically very close to the academy in Wandlitz (see above) – less than 1 straight mile away – the bunker in Prenden is the central piece of a network of bunkers and military hardware, designed an built on behalf of the National Defense Council (NVR) of the GDR from 1973 onward, and named ‘komplex 5000’. The purpose was protection of the leadership of the GDR in case of a crisis or attack from the West.

The bunker is Prenden, technically listed as ’17/5001′, was a control center of incredible sophistication, designed to withstand nuclear blasts, and with direct communication with other sub-nodes of a larger communication network, thus granting safe communication and broadcasting ability, allowing to lead the country in case of a crisis. The bunker was intended to host the general secretary of the communist party, i.e. Erich Honecker, when the bunker was commissioned in 1983 – hence the unofficial name ‘Honecker bunker’.

The premises of Prenden are now largely in private hands, but some parts are apparently publicly accessible – the original fence has been completely torn down. The bunker itself is sealed, and can be accessed only on a few days per year with a guide.

The official entrance to the area is through the original GDR-made gate. This is closed however, for it is now the entrance to a small private industrial complex.

Traces of the original fence, as well as piping and vents for underground rooms, can be found around the hill on top of which the installation is standing.

Some service buildings in typical communist style can be still found, despite demolition works having taken place. Proximity sensors and signs delimit the private property area.

The three-storey building on the southwestern corner of the complex used to be the ‘front office’ of the bunker. Today, it is in a really bad shape.

Inside, traces of the original furniture and services can still be found, albeit much deteriorated.

Access to the bunker is on the underground floor. You may notice the prison-like railings ahead of the access stairs. A feature that might make you jump when you are exploring alone – if walking in a forgotten communist government building, deep in the silent German countryside, was not enough… – is the lit bulb hanging over the entrance to the bunker – really unexpected!

Besides the building, a shelter-garage for trucks and cars is still in a relatively good shape.

Getting there and moving around

The Prenden bunker is not publicized, but it can be neared easily with a car, about 1 mile south of the small village of Prenden, along Utzdorfer Strasse. The gate can be clearly spotted, but it will be likely closed, and there are obvious ‘no trespassing’ signs and labels of private companies. You may park outside and proceed along the side of the property to the back of it, where the abandoned building mentioned above can be found. Whether this is still on private land or not is not very clear. There are proximity sensors between the abandoned building and the rest of the complex, likely to trigger inspection if you get too close to the (surely) private part of the complex.

Venturing in the building is definitely not safe, and the bunker entrance is usually closed. Official visits to the bunker are possible on guided tours arranged irregularly about once per month (please browse the internet for more info on visiting, cause I could not find an official site of the place to link here).

Cold War Forts and Museums in Denmark

During the Cold War the condition of Denmark on the international stage was among the most complex. Coming from years of neutrality before WWII, conquered in a matter of days in spring 1940 by neighbor Germany, at that time in the throes of the Nazi fury, it found itself on the front line of the two opposing blocs soon after May 1945.

Having not been occupied by the Soviets during WWII, it could better choose about its future, and in 1949 the mother country of the Vikings joined NATO as a funding member – unlike neighbor Sweden and Finland – thus giving its availability to its Allies to help countering Soviet influence over the territory under its control.

History in brief

Often overlooked when looking at the world map for its relatively small area, at the beginning of the Cold War the geographical position of Denmark nonetheless was – and, to some extent, still is – strategically very relevant. It is right on the inlet of the Baltic Sea, with a proximity to the foreign coasts of Norway and Sweden such to allow easily blocking the marine traffic on the Kattegat strait, when needed, by means of mere cannon fire from the coast. During the Cold War, this meant a virtual control over a sea where the USSR and Eastern Bloc Countries had many industrially relevant and non-freezing ports, as well as navy bases. Furthermore, the islands of Denmark, where large cities like Odense and Copenhagen are, can be found as close as 1.5 hours by boat to the coast of the German Democratic Republic – once one of the most heavily militarized countries on earth, also thanks to a massive Soviet presence. The smaller island of Bornholm, further east, is even closer than that to the coast of Poland.

A curious fact in history demonstrated the proximity of Denmark to the communist sphere of influence, shaking the minds of top ranking Soviet military. On March 5th, 1953, on the very same day of Stalin’s death, the first defection of a jet fighter from the Eastern Bloc took place, when a Polish MiG-15 on a routine flight along the Baltic Coast suddenly left his mates and rushed to Bornholm, where it landed on a field, leaving the aircraft in almost pristine conditions.

The cautious reaction of the Danish government and military forces reflects the position of the country at the time – they had identified the USSR and their satellites as a clear and present threat, and consequently they had taken the side of the West. Yet Denmark knew it could not withstand a direct military hit by the Soviets for more than a few hours, therefore as a form of self-protection, any form of provocation, at least in the early 1950s, was carefully avoided. While the pilot of the MiG was allowed to escape to the UK and then the US, the aircraft was quietly ceded to the US military for technical inspection in the FRG, but then re-mounted and returned to Poland. Other examples of a policy of constant detente with the Soviet Union are represented by the refusal to have NATO bases on its territory, or despite the adoption of the Nike missile system for the airspace protection, the missed deployment of the corresponding tactical nuclear warheads.

Of course, in recognition of the strategic relevance of this pleasant country, plans for a Soviet invasion which would strike in northern Europe, with the objective of reaching to the ports of the North Sea in less than a week from Eastern Germany, included as a major target the quick occupation of the Jutland peninsula, and of the islands of Denmark as well. This had to be done by marching fast through the northern regions of the Federal Republic of Germany, and simultaneously landing troops on the Danish islands.

About this post

Albeit not enough populated to sustain an army capable of resisting the eastern opponents on the other side of the Iron Curtain, thanks to its position on the map, Denmark took over seriously a fundamental border monitoring and interdiction task in favor of all NATO forces. Two tangible witnesses of this are the military bases of Stevnsfort and Langelandsfort, both located on the southern coasts of the islands, overlooking key sea straits, and pointing south to the East German coast. Both have been shut down after the end of the Cold War, and now they can be visited as top-tier military museums.

Further souvenirs from the Cold War era can be found in the Defense and Garrison Museum in Aalborg, a wide-spectrum military museum with a focus on WWII and the Cold War, and in the Danish Museum of Flight, where exemplars from the heterogeneous wings of the Danish Air Force are displayed, together with unique specimens of Danish aircraft production from the inter-war and early Cold War period.

This post covers all these four sites, visited in summer 2019. Presentation doesn’t follow any special order.

Cold War Museum Stevnsfort

This museum on the eastern coast of the island of Zealand (the same of Copenhagen) is actually a former Cold War military fort, operative from the early 1950s to the year 2000. It was re-opened as a museum in 2008, carefully preserved in most part in the forms it had in the 1980s, the most technologically advanced years of the Cold War.

By the entrance to the museum area you can see three surface-to-air missile, namely an old Nike-Ajax, and a much more performing – and bigger – Nike-Hercules. Both were part of the US Nike airspace protection system, which was deployed in Denmark around Copenhagen. The missiles are from the Cold War years, but were not originally present on Stevnsfort.

Strictly speaking, Stevnsfort is not the part of the installation you access first. The area you meet when getting in from the parking used to be a missile base in charge of the Danish Air Force. It was built for the Hawk system, another US interdiction surface-to-air missile system, the heir of the Nike system. Actually, Nike Hercules batteries in Denmark were withdrawn from use – as elsewhere, see this post – in the 1980s. Their role was taken over by Hawk missile batteries, gradually entering service since the 1960s, and operated till 2005 in Denmark.

Differently from its predecessor, the radar-based Hawk system was entirely movable, making it more flexible and less vulnerable. As a result, there are basically no bunkers in this area, and all constructions here are ‘soft’. Target designation and tracking was demanded to three sub-systems, namely a radar-pulse antenna for target individuation, an interrogation friend-or-foe (IFF) and a target-tracking/homing antenna.

Two radar-pulse antennas are displayed. The aerial emerges from a tent, which covers the electronics and motor of the system. Both are mounted on a truck trailer, which is actually totally movable. The range of the radar scanner was about 75 miles.

The IFF antenna is a smaller barrel-shaped device coupled with systems on-board aircraft, needed to distinguish between an enemy aircraft and a friend or ally. The target-tracking/homing antenna, with its distinctive two radar dishes, shares the installation setup with radar-pulse antennas – it sits on top of a trailer, covered in a green tent.

Close by, trucks and special moving cranes to mount the missiles on their launch gantries are displayed. Also containers for the missiles are shown, together with an example of the Hawk missile itself. The launch order could arrive only from the central Air Force command, except in case of a communication breakdown, when each missile base could decide on its own – at the high risk of making a mistake!

Farther on, power trucks and other launch systems are displayed besides batteries of Hawk missiles. The launch gantry is smaller in size compared to that of Nike-Hercules, but each gantry launches three missiles instead of only one. The gantry is anchored to the ground, and when inactive it is shrouded in a peculiar rubber-coated eyelid-like bubble, which can be quickly lowered to let the missiles out.

On the far end of the missile area, you can see an old-fashioned coastal cannon, part of the original fort, used as an illumination cannon in support of larger cannons in the battery.

One of the naval gun batteries is the first item you meet when entering the actual Stevnsfort fort. The fort was built between 1952 and 1955 for use by the Navy, and is the oldest part of the installation. Together with the Langelandsfort gun battery and command post (see below), it was tasked with monitoring marine traffic along the straits giving access to the Kattegat and the North Sea from the inner Baltic. For the purpose, it was supplied with a huge underground bunker, its most distinctive feature, as well as batteries of naval guns.

The 150 mm guns have an intriguing history. They were made in Nazi Germany early during WWII, for the Kriegsmarine ship ‘Gneisenau’. This was damaged when still in the dockyard, and the guns were re-designated to be placed on the Danish island of Fano on the North Sea coast, as part of the fortifications of the Atlantic Wall. Following the end of WWII in May 1945, the guns were captured and finally found their way to Stevnsfort.

The two-guns batteries were capable of 4-6 shells per minute per barrel, and could reach to the coast of Sweden, thus effectively closing the Oresund strait between Denmark and Sweden if needed. While primarily an anti-ship battery, the swiveling turret could be used to cover the coast, in case of an amphibious attack.

Firing direction was by means of a primary radar station on site, which is still in use, complemented by five other stations along the coast. The shells were loaded with an elevator from the bunker underneath. The guns were temporarily deactivated – but not dismantled – in the 1980s, when Stevnsfort assumed the role of main control and communication post for the southern district of the Danish Navy. Joint exercises with the military forces of the FRG were carried out also here in the final years of the Cold War.

By the entrance to the underground bunker you can spot several air hatches emerging from the ground, and an example of sea mine. The latter was the primary weapon to interdict traffic on the strait, with gun battery fire being mainly directed against enemy mine-sweepers.

Past the entrance, you need to descend a long stair into the bunker. At the base of the stair is an airlock with facilities for decontamination. The Stevnsfort bunker was most notably the first structure in Denmark to be built to withstand a nuclear attack.

The bunker is not excessively big, with about twenty reinforced-concrete-padded rooms connected by tunnels carved in the rock.

One of the highlights of this installation is the communication bunker, operative since 1984 in an area formerly hosting a hospital, then shut down when the naval batteries were deactivated. This used to be a highly inaccessible facility during the Cold War. Thanks to a careful preservation, the room looks like it was still in use! Batteries of telex and other communication machines originally in place, monitors and modern imaging technology from the Eighties, together with examples of ciphered messages are all on display.

Next to the communication room, the operation room is even more impressive. Similar to the former, it was constantly manned, and totally inaccessible for non-authorized personnel. The radar monitors can be seen towering over the consoles! Military staff on duty identified and followed all marine traffic in the assigned district, both civilian and military, friends and potential enemies.

Catalogs of existing ships are on display. Several thousands ships were identified and observed from this facility in the days of operation. It is reported that patrol ships from the USSR approached the coast under surveillance about 30 times per year, tasked with familiarizing troops with local geography…

Another highlight of the visit is the ammo storage for the gun battery previously visited. In the storage, explosive cartridges are placed separately from the shells themselves. There were four types of shells, recognized through a color code – grey for armor-piercing, orange for explosive, green for illuminating and blue for inert.

The almost-100 pounds cartridges were loaded on an elevator, and lifted up to the battery. A ladder provided direct access from the bunker to the cannons, serving also as an emergency exit.

Other rooms you can visit are sleeping quarters for the 250 men which stationed inside the bunker, until the guns were deactivated in 1981. The fort was capable of sustaining prolonged isolation in case of crisis or war. During the Cuban missile crisis, the Stevnsfort bunker was put on maximum alert for a week, with all men living underground, all accesses sealed.

Getting there and moving around

The Cold War Museum Stevnsfort is an international-level museum, to be found 1 hour driving south of central Copenhagen. The official website with directions and opening times is here. Visiting inside the gun battery and the bunker is possible only on a guided tour, where you are given an audio guide in English (also German and possibly other languages) if you can’t follow the Danish-speaking human guide. The guided tour includes also a visit of the missile battery, but this part can be toured also on your own. The guided visit lasts about 1.5 hours, and may turn a little boring in some parts (as usual, the human guide speaks longer than your audio-guide), but it is needed to get access to the most unique parts of the museum. I suggest visiting relatively early in the day, allowing some spare time after the guided tour and before closure to tour the missile part on your own. Free parking ahead of the installation, nice military-themed shop.

Cold War Museum Langelandsfort

This museum has been opened on the premises of a former naval gun installation from the same years of Stevnsfort (see above). Located on the southern island of Langeland, at the inlet of the Belt channel giving access to the Kattegat from the Baltic, it was in a good position to monitor all marine traffic in its sector, as well as for blocking the channel. As a matter of fact, similarly to Stevnsfort, the main target of the naval guns here were minesweepers, for the channel was completely covered with Danish remotely-controlled sea mines, and action of enemy minesweepers would have been necessary before any attack by the bulk of navy forces.

The main naval force in Langelandsfort was constituted of four naval guns, mounted on swiveling turrets, and a fire control bunker which in non-crisis time was used to keep trace of all marine traffic in the sector. The fort was complemented with anti-aircraft defensive positions, a bunkerized power station, and ‘softer buildings’, including barracks. Except for the latter, everything has been restored and can be visited. One of the naval batteries has been restored completely to its original form including the mechanisms underneath, whereas at the base of the other three batteries you can find exhibitions about various aspects of the Cold War – they are all pretty well studied, rich and interesting.

The command bunker is the first construction you meet. The building is from the 1950s, and it shares many aspects with Stevnsfort, though this is much smaller. You can see sleeping quarters and a kitchen, which would be used especially in case the fort was sealed, i.e. in case of high alert or war.

The control rooms are three. Two are for tracking marine traffic in the marine district of the Belt, and also for coordinating air operations from other military installations in Denmark. A radar antenna and an observation tower outside, likely complemented by similar gear in the area, provided a complete real-time picture of the civilian and military traffic in the sector. It is reported that ships going to Cuba with SS-4 nuclear missiles and related supplies were spotted in these rooms months before that material was photographed by the US, when the crisis broke out.

The third control room is the fire control room for the whole fort, coordinating fire from all four gun batteries. Fire control was by means of a very interesting piece of machinery, a fully mechanical computer, taking in atmospheric data like temperature, humidity, wind direction and speed, and target data. No electricity was needed except for lighting the goggles of this analog computer! A similar item was present in Stevnsfort, but I could not see it during my guided visit.

In an adjoining room you can see a perfectly restored communication facility, with ciphered messages hanging on the walls, as well as original transmission machines and early computers. There is also a personal study room for the commander of the post.

Besides the control bunker you can find an anti-aircraft position, centered on a four-barreled anti-aircraft gun. Similar to all others, the small bunker underneath could be manned and sealed in case of war.

The cannon battery closest to the control bunker has been restored completely, including the bunker underneath. The 150 mm guns, one per battery, were made in the final years of WWII by Skoda works in Plzen, in the then-Nazi occupied territory of Czechia. They were originally intended by the Wehrmacht for the Atlantic Wall in Denmark, but they never became operative there. Instead, they ended up to be installed by Denmark to counter a Soviet threat on the Baltic.

The mechanism for supplying cartridges to the cannon is similar to that in Stevnsfort, with an elevator lifting the explosive charge and the shell separately to the level of the gun. However, here the storage bunker is just beneath the cannon, and the lift does not carry the cartridge directly inside the turret, but to a hatch in the reinforced wall besides the cannon – something similar to some of the smaller cannon batteries of the Atlantic Wall built by the Germans.

Inside the bunker you can see the ammo storage, as well as a sleeping compartment for the 15-men crew needed to operate the cannon.

Some example shells have been preserved, with colors corresponding to different functions of the shell (see Stevnsfort above).

The cartridge elevator room is very small, and access is from both sides. Explosive and shell came from opposite directions, each from the corresponding storage room.

The bunker under the next cannon battery has been dedicated to the analysis of the threat from the Danish perspective. Here you see copies of the Soviet plans to invade Denmark, as part of an operation to conquer central and northern Europe lightning-fast in case of an open war against the West. Among the most striking items, you can see detailed Soviet maps covering all regions of Denmark – with city names and all writing in Cyrillic!

There is also a nice collection of ordinary weapons and military supply from the Eastern Bloc, and especially from the neighboring German Democratic Republic. A very special feature is an example of the ‘Blücher decoration for valor’, a medal created by the GDR to be attributed to individuals for actions of exceptional courage in the defense of the GDR, and to be assigned only in case of war – thanks to the Cold War never turning ‘hot’ for the GDR, nobody could be awarded this decoration.

The next battery is dedicated to espionage and spy gear, with many examples of James-Bond-like trinkets, actually used by both enemy and Danish spies. Machinery for ciphered communication, once considered hi-tech, is also on display, together with maps used by a Danish spy visiting the Polish coast, and satellite imagery of East German/Soviet airbases.

The exhibition in the last battery is about the Cold War and society, and is full of old photographs of pro-Soviet protesters in Denmark, spies, famous characters of the Cold War, momentous events taking place in Denmark during the Cold War and so on. Most notably, there are also many artifacts from both Denmark, the Eastern Bloc and the USSR, including medals, posters, portraits and much more.

Similar to the control bunker, the power station has been preserved in its original condition. Three diesel engines could provide power to all bunkers in case of war or failure of the grid for whatever reason. Immediately outside the entrance to the power station bunker there are apparently some suspended showers…

The large area of Langelandsfort has been selected also for the exhibition of a submarine, a mine-sweeper and two aircraft! The submarine ‘Springeren’ was used by Denmark in the 1990s and early 2000s, but it was built much earlier and operated by the Norwegian Navy. Sadly, after the retirement of ‘Springeren’, the Danish Navy shut off completely its underwater branch. The ship is a small conventionally powered attack submarine. The interior is apparently pretty modern with respect to older German or US WWII U-boats.

The submarine features six torpedo tubes.

The mine-sweeper has the appearance of a small conventional boat, but with room for a crew of several men. It is hosted in a hangar together with examples of sea mines – apparently US models.

The two aircraft are a SAAB Draken of Denmark and a MiG-23 of Poland. They represent some of the most advanced aircraft of these opposing countries at the height of the Cold War. Both exemplars are well preserved inside hangars protecting them from the weather and sunlight.

Another interesting sight is a reconstruction of a civil defense bunker, with much original material, including packs of ration cards already prepared for the population in case of war. In an adjoining room you can see a reconstruction of a bunkerized broadcasting studio – the national TV channels were tasked with providing updates to the population in case of an attack, hence a similar facility was prepared in the basement of the TV headquarters.

Close to the ticket office, you are offered a very well-designed exhibition tracing the timeline of the Cold War, with some clever text and many pictures, some of which rather uncommon – really worth spending some time on, before or after visiting the museum.

There is also room for temporary exhibitions, in a hangar which includes an original section of the Berlin Wall.

The building of the ticket office is also interesting. From the back of it you can get access to a smaller exhibition about travels to the DDR (the native acronym for the GDR), with everyday items, old Interflug boarding passes, and some incredible postcards – apparently, modern Soviet-style housing and heads of Marx were the items that GDR postcard-designers liked most… Fragments of the Berlin Wall are also on display.

Ahead of the entrance there is an old and pretty big hammer and sickle, originally from a Soviet ship. The commander threw it outboard when the Soviet Union officially ceased to exist. It was collected by a Danish sailor and ended up here. Nearby you can see a reconstruction of the Berlin Wall, and an original Trabant crossing it.

Getting there and moving around

The Cold War Museum Langelandsfort is located close to the southern tip of the island of Langeland, which is connected with bridges to the major island of Fyn, where Odense can be found about 1-hour north of the museum by car. You can move around the museum on your own, there are several panels with explanations. Most panels have at least a quick translation in German and English. All presentations are very well designed and maintained. Visiting may take at least 2 hours for an interested subject, and even more especially if you are taking pictures. Free parking ahead of the entrance, and picnic area nearby. Official website here.

Aalborg Defense and Garrison Museum

This museum was opened in the year 2002, in the hangar of a seaplane base constituted by the occupying German forces in 1940. The base was potentiated in more instances during WWII, and a half-interred command bunker similar to those of the Atlantic Wall was added.

Aalborg has been a military post for centuries, therefore the museum is centered on several aspects of war and military life. Of course, the majority of the artifacts on display date from WWII and the Cold War period.

The hangar hosts a small collection of aircraft, which capture your sight when you get in. Most notably, there are a venerable F-84, an F-86, and somewhat older T-33 and Gloster Meteor.

Close by, you can find a more modern F-104. Jet engines of American make from some of these aircraft have been taken out of the airframes, and put on display separately.

Again in the center of the hangar you can see a Hawk missile system, including the missile battery and movable power and control trucks. Also anti-aircraft guns and searchlights from various ages are on display.

Items from WWII include a nice exhibition of locally-collected gear used by the Danish resistance movements. Supplied by the Allies from the air, they managed to build several types of bombs, mines, and so on, made to disturb and damage enemy transports, or to kill enemy staff in well programmed para-military actions.

Memorabilia include the engine of an US B-17 bomber, sadly downed over the Baltic during the crew’s final mission, the original Luftwaffe eagle once standing on the building of the local German air command, and a Nazi flag weaving on some public building in town in the years of the German occupation.

There are also many photographs from the area from the war years, and reproductions of German maps and local newspapers. The latter tell about relevant facts taking place during the war, as reported by the local media. There are also diplomas of merit issued by the US and Britain in favor of a local citizen, member of the resistance.

A part of the exhibition is about civil defense. Similar to the US, Britain and other countries during the Cold War, this service was activated to prepare the population to a nuclear war scenario, and to provide shelter and a chance of survival, by means of bunkers and deposits of supplies. Here you can see a reconstruction of such a shelter, and items which used to be stored in preparation for survival in the nuclear winter.

There is also a nice collection of light weapons from local firms, uniforms and communication rigs.

A few uniforms and technical gear from the current supplies of the Danish military are on display as well.

In a room to the side of the central hall, you can find uniforms dating from WWII, including German stuff. The story of a Dane coming to the US and fighting for the US Army is also told in a corner, also through some memorabilia.

On an elevated platform you can find an exhibition about the Cold War. This is mostly made by panels retracing the history of that confrontation over the decades. Among the most peculiar items on display, a copy of the invasion plan studied by the Soviet in case of a sudden war with the West. That plan included the rapid conquer of Denmark, due to its strategically relevant position. A copy of a Soviet-made map of Aalborg in Russian, needed in case of war, is another example of the unique artifacts on display.

This special Cold War exhibition is completed with a set of field and anti-aircraft weapons from various ages of the confrontation.

Other rooms around the main hall display modern uniforms, NATO-related material, military supply from various ages and even a throne used by the Queen of Denmark on an official visit.

In an adjoining smaller hangar you can find a rich collection of trucks and weapons with various – not only military – functions.

Outside, a highlight of the museum is the former air command bunker built by the Germans. This has been filled with memorabilia from the Nazi occupation period. An unusual and little-known story is told here, about the German refugees from Eastern Prussia, a region loosely coincident today with the part of Russia around the town of Kaliningrad (ex-Konigsberg). This area used to be part of Germany since before WWI, and it remained under the Weimar Republic, even though separated from German mainland. Neighboring Lithuania was annexed to the Third Reich before WWII – similar to Sudetenland – on account of the proximity to that region, with the excuse of a significant German group living in Lithuania. In 1939 the Germans re-gained control over northern Poland, and the two regions of Prussia were reunited in the Reich.

Following the victories of the Soviets in 1944 and the ensuing landslide-march towards Berlin, Eastern Prussia was lost to the enemy. Refugees escaped to mainland Germany, and the administration of the Reich sent these folks in several areas relatively far from the front – including a significant number to occupied Denmark, and especially in the hangars in Aalborg, where the museum is today. So the hangar acted as a hospitality center for the refugees. This was something strange though, for the refugees were not local nationals, but instead enemies. This led to a controversy soon after, when the war ended. In the event, most of the refugees returned to their land of origin, only to find it permanently occupied by the Soviets. Some handmade artifacts of these German refugees can be seen on display in the bunker.

Finally, a very good collection of tanks, field guns and movable howitzers from various countries including the Eastern Bloc and mainly from the various ages of the Cold War can be admired on the museum apron. For the most part, these are reportedly kept in working condition.

Getting there and moving around

The museum is located close to central Aalborg, on the waterfront. You can visit it totally on your own. Some of the exhibitions are described in more languages, but some parts are in Danish only. Nonetheless, the visit can be very rewarding for experts and for the kids as well, thanks to the chance to touch many of the artifacts on display. A two-hours time may be enough for having a look, more time is required for a more in-depth visit or if you want to take pictures.

Convenient parking just ahead of the entrance. Website with full information here.

Danish Museum of Flight

This fantastic collection of aircraft can be found next to Stauning Airport, on the west coast of Jutland, at the level of the Ringkobing firth. This is by far the largest aircraft collection in Denmark, and the reference air museum in this country.

The exhibition is well designed and rich, and it covers both the civil and military branches of aviation. Furthermore, a good half of the aircraft appear in fully airworthy conditions.

There are three thematic hangars. In the first you can find civilian aircraft from various ages, smaller sport aircraft and military trainers mainly from the inter-war period or the late 1940s. Some of them appear airworthy.

Most notably, there is the front part of the fuselage of a Douglas DC-7, formerly in service with the national carrier SAS, still on business today. The cockpit and the crew compartment are well preserved. The analog instrumentation adopted on this plane, which dates from 1957 and represents the last and most advanced of the Douglas propliners, is abundant and remarkably sophisticated.
