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.

Berlin Airlift 70th Anniversary Celebrations in Schleswig-Jagel

The blockade imposed by Stalin on the jointly administrated city of Berlin in the spring of 1948 dissipated any doubts on the post-WWII attitude of the Soviet Union towards their former allies in the west. The ensuing joint effort to support the trapped population of Berlin resulted in one of the major airlift operations in history – the Berlin Airlift, or Luftbrücke in German language. In June 2019, 70 years after the end of the blockade, Germany hosted a great celebration for the anniversary of this vital operation.

History – in Brief

The blockade started slowly, with trains crossing the Soviet occupied territory – soon to become administrated as a new state, the communist German Democratic Republic – between Berlin and western Germany forced to stop and go back, truck routes closed, increased controls at border checkpoints. In early summer, the city was completely isolated from the west.

The Soviets tried to motivate the move with treaty violations by the western forces, but this did not receive much credit by the administration of President Truman in the US, nor in Britain, France, or the occupied territories of western Germany. To mitigate the lack of coal, food, drugs and other goods of primary use for the local population, the joint forces of the United States, Britain, France, South Africa, Australia and New Zealand set up a massive airlift under the coordination of the US military.

Over roughly a year more than 275’000 flights were carried out, mainly between three airfields in the territory of western Germany – Jagel, Fassberg and Wiesbaden – occupied by the western Allies, to Berlin Tempelhof downtown airport (see this post), as well as other land and water bases in the cut-off urban area. These were operated with a variety of transport aircraft, including Douglas C-47 and C-54 twin and four-propeller cargo planes manufactured in the US, as well as several British models, including some Shorts seaplanes.

Stalin opted to avoid an escalation. The blockade was finally lifted by the Soviets on May 12, 1949. The situation was stabilized with the birth of the Federal Republic of Germany in the west, and of the opposing German Democratic Republic in the east, later the same year. The western sectors of Berlin were to remain an enclave of the free world deep in the communist bloc for slightly more than another 40 years, when the GDR – aka DDR in German language – finally ceased to exist, and the re-unification started.

A great museum tracing the history of the presence of the western Allies in Berlin, telling the history of the Airlift in great detail, is the Allied Museum (website here) in the former US sector of Berlin-Zehlendorf.

70th Anniversary Celebrations in Germany

In 2019 the 70th year since the end of the blockade, lifted as a result of the airlift effectively sustaining the population of Berlin for an entire year, was celebrated with the patronage of the German government with a series of unique aircraft-related events. The most prominent were a few formation flights of an incredible group of historical aircraft, between the airfields formerly used as supply bases for the airlift.

One of these, the still-active military airfield of Jagel, in Schleswig-Holstein some 60 miles north of Hamburg, hosted a ‘spotter day’ on June 13th, 2019, when a few hundreds photographers were admitted for the whole day on the premises of the airbase, to assist to the landing, departure and flypast of a fleet of nine Douglas C-47, a major workhorse in the days of the airlift.

This marked possibly the largest grouping of such historic aircraft in Europe since many years. But what made the event even more unique – besides the weather, incredibly mild for the region… – was the origin of the aircraft, which except for one are all based in the US. They crossed the Atlantic once more to parade in the celebration of the 75th anniversary of the D-Day in Normandy, attended also by President Trump and Charles, Prince of Wales. A few days after, they toured Germany for the 70th anniversary of the Berlin Airlift.

Besides the commemoration flight, normal flying activity was carried out during the spotter day around the airbase, so this was a good chance to assist to flight operations by Tornados and Typhoons of the German Air Force, as well as other military aircraft.

Historical Flight – Fly-in

A single C-47 arrived earlier than all others, anticipating the massive fly-in of the full wing of Douglas C-47 twin-prop liners. Later on, a flypast all Skytrains to take part in the event started from the east of the field. The aircraft then landed one by one, taxied ahead of the photographers and after a stop of a few hours, took off in a row for another location in Germany.

US Air Force C-47A/DC-3C ‘Miss Virginia’

The first aircraft to come was ex-USAAF 43-30655, built in 1943 as a military C-47A. The aircraft fell in private hands in the 1970s, after yeast stored in Arizona, when it was converted into an DC-3C, an energized version of the original 1930s design. It spent the 1980s in Colombia, then returned to the US as a utility aircraft. It was finally acquired for restoration and given the nice US Air Mobility Command colors it bears today. It flies with the civilian registration N47E.

Golden Age Tours C-41A

This incredible aircraft, now in civilian hands since long, is a unique example of an executive version of the original 1935 DC-3. Built in 1938, it entered military service soon after as a private flight for Maj. General Henry ‘Hap’ Arnold – an instrumental figure in the reorganization of the US military forces upon the early 1940s. It went on keeping its original executive configuration, and today it is lent out for special flights and for filming purposes from its base near San Francisco, CA. It bears the civilian registration N341A.

USAAF C-47A 43-30647 ‘Virginia Ann’

This aircraft was in service with the USAAF since 1943. It took part to the D-Day operations with the name ‘Virginia Ann’, but was put on storage soon after WWII. It later went to private owners and was based in many domestic locations, including being part of the famous Planes of Fame collection in Chino, CA (see this post). Today it is still based on the West Coast, with the registration N62CC.

Chalair C-47B

This C-47B was built among the latest in May 1945. It was surplus for the USAAF soon after WWII, so it joined the Royal Air Force inventory, and from there it left for Canada, where it enjoyed many years of service as a VIP transport in the Royal Canadian Air Force until the 1970s. It reportedly served as a Royal Flight for the Queen of England during a visit to Canada. After withdrawal from active service and changing hands several times in Canada, it was finally acquired in France and totally restored in the late 2000s. It flies with the registration F-AZOX.

Johnson Flying Service, Inc. C-47 ‘Miss Montana’

This incredible aircraft was built soon after the WWII, and as many other surplus C-47, it moved to the civilian market. This aircraft was used in firefighting operations over the Northern Rockies, and was even involved in a tragic accident, crashing in the water causing fatalities. It was drawn back to a second life through the effort of the Museum of Mountain Flying in Missoula, Montana, where it is based now, with the registration N24320.

Legend Airways C-47D/DC-3C ‘Liberty’

A true combat veteran of WWII, this aircraft was pressed into service with the USAAF in mid-1943, and took part in operations in Algeria and the Mediterranean, as well as the D-Day in Normandy, where it sustained direct hits from German anti-aircraft guns. Soon after the turbulent war years, after returning to the US it fell into private hands in the south as a corporate transport. It kept the role, undergoing several upgrades, until it was finally acquired for a lavish restoration and cabin refurbishment, which gave it its current appearance. It is based in Colorado, where it is being operated for pleasure flights and filming, with the registration N25641.

Pan American Airways System C-47B/DC-3

This aircraft had an adventurous history between its entry into service in 1944 and the early 1950s. It was originally allocated to the Chinese National Aviation Corporation, which in the war years carried out covert flights over a route known as the ‘hump’. These allowed resupply of Chinese forces from the British Empire in India, through resupply flights over the high peaks of western Tibet. This aircraft flew on that very dangerous route, until the breakdown of the Japanese forces and the end of WWII. As the Chinese National Aviation Corporation reverted back to normal operations, this aircraft was turned into a commuter between Hong-Kong and Canton. In the meanwhile, Mao Tse-Tung communist revolution subjugated China overturning the government. The new dictatorship tried to grab as many aircraft as possible, which in the meanwhile tried to escape from the country, assisted by western powers. This very aircraft, after some years on ground in China, was finally allowed to leave for the US, where it arrived in 1953. Since then it was refurbished as a corporate aircraft, and enjoyed a long career, being finally restored with a VIP internal layout and carefully reconstructed 1953 on-board systems. It is registered as N877MG.

USAAF C-47DL 43-15087

The aircraft you see flying is indeed a WWII veteran, but not with the colors you see today. The number 43-15087 on the tail refers to a C-47 which actually took part to the operations over Normandy on June 6th, 1944. But the airframe you actually see entered service with the USAAF as a personnel transport in North Africa and the Middle East in 1943. It then went to the Armee de l’Air in France, then to civilian operators in France and back in the US after the 1960s. There it was later restored and changed livery several times for special occasions, like the 75th anniversary of the D-Day – the ‘9X-P’ designation you see now. It is based in Texas, with the US registration N150D.

USAAF C-47 42-26044 ‘Placid Lassie’

Pressed into service in the summer of 1943, this aircraft is a true combat veteran, having flown on June 6th, 1944 over Normandy, and in September 1944 for several times over Flanders during the ill-fated operation ‘Market Garden’. It then went on as a civilian transport in the continental US. After years spent in disrepair, it was drawn back to life in the 2000s, and is now flown by a foundation dedicated to the crew of ‘1D-N’ during WWII.

German Air Force Aircraft

As the historical flight performed basically a fly-in and fly-out, in the few hours between them the aircraft of the German Air Force – the Luftwaffe – and of the Navy – the Marine – based at Jagel flew for the public. There were also German aircraft taken there in preparation for the day of the Armed Forces – Tag des Bundeswehr – to be celebrated the following week-end with an open day of the base.

Jagel is the home base for the Taktisches Luftwaffengeschwader 51 ‘Immelmann’, which currently operates the Panavia Tornado. These massive swing-wing aircraft flew in several time slots during the spotter day.

Small formations demonstrated refueling abilities.

Some passages were performed at high speed, with maximum sweep.

One of the aircraft has been painted in a flamboyant celebration livery, with the portrait of Max Immelman, a German WWI ace, on the vertical tail.

Another impressive performance was given by a Eurofighter Typhoon, a massive delta-winged twin-jet with a tail-less, all-moving canard configuration. This compares well in size with the Super Hornet – a pretty massive attack aircraft.

This very aircraft is from the Taktisches Luftwaffengeschwader 31 ‘Boelcke’, based in Nörvenich.

At some point in the day, there was a flypast of a single Lockheed P-3 Orion, on strength to the German Navy – Marine. On its double passage it was possible to see the large racks for sonobuoys under the belly of this four-propeller aircraft.

There were also exhibitions by some rotorcrafts, including a huge Sikorsky CH-53G, an Airbus H145 and a larger NH-90, the most modern of the three. The very dark camo livery made them pretty difficult to photograph, despite a rather wide zoom lens I was using for the task.

Finally, a pretty rare aircraft, albeit possibly not so eye-catching, a single Dornier Do-28 military light transport landed in the evening.

Visiting Aircraft from Other Countries

Other aircraft landed and departed from the base, some possibly in preparation for the Tag des Bundeswehr to be held a couple of days later. These aircraft were not from Germany.

First, two more Tornadoes of the Italian Air Force landed at some point, and posed for photographers. They belong to the 6° Stormo ‘Diavoli Rossi’, based at Ghedi. A small devil’s face is painted on the vertical tail of these aircraft.

A SAAB JAS-39 Gripen of the Hungarian Air Force, in a twin-seat configuration, landed soon after.

A single Aero L-159 Alca of the Czech Air Force appeared at some point.

An Antonov An-26 of the Hungarian Air Force landed and later departed. An iconic Soviet-made transport, this sturdy workhorse is still flying in many Countries, both for the Armed Forces and for civilian operators as well.

A single Pilatus PC-9 of the private company Qinetiq made an appearance.

Finally, two pretty rare Douglas A4 belonging to the Canadian private training company Jet Aces landed and taxied for the photographers, one of them in a rather eye-catching NATO anniversary commemoration livery.

Final Note

The Marine base of Schleswig-Jagel where this event took place was originally a Luftwaffe airfield, operated by the British military during the Berlin Airlift and until the early Sixties, and later handed over to the Federal Republic of Germany. It is still today an active airbase. There is no public access except on special occasions.

Plokstine – A Preserved Nuclear Missile Site in Lithuania

While almost all nuclear sites you can find in European Countries once beyond the Iron Curtain are today totally abandoned and fairly unaccessible, there exists a perhaps unique exception. The Plokstine site in northwestern Lithuania has been selected around 2010 for complete refurbishment with the help of public money, and in 2012 it has opened its doors as a museum. Located in a beautiful natural setting crowded with hikers – namely Zemaitija National Park, a national recreation area around Plateliai lake – it has quickly grown to international fame, and is now recording several thousands visitors per year, with guided tours in multiple languages – including English – offered on a regular basis during the warm season.

What is today an intriguing tourist destination, used to be part of a large Soviet installation for launching ballistic missiles armed with nuclear warheads. It is worth mentioning that Lithuania was a ‘Soviet Socialist Republic’ in the realm of the USSR, i.e. not just a satellite country of the Soviet Union, but part of it. Actually, this small country on the shores of the Baltic Sea, on the extreme western border of Soviet territory, was an ideal location for deploying weapons to hit European targets from within the Union. Furthermore, the Plokstine forest was – and still is – a little populated area, where construction works for a large top-secret military facility for storing and operating offensive cutting-edge hi-tech warfare would go likely unnoticed.

The missile complex was completed in December 1962, in the years of Khrushchev and Kennedy. The Plokstine site comprises of four interred silos and an extensive underground command station in the middle – the ensemble constituted a so-called ‘Dvina’ launch complex.

The ‘Dvina’ site in Plokstine was actually the last part of the missile base to be built. Two more sister surface sites, with four launchpads each, had been completed one year before, just west of the nearby village of Saiteikiai. These surface sites were similar to those you can find in Latvia (see this post), a neighbor country where unfortunately the last remaining ‘Dvina’ site was demolished in 2017, but abundant traces of the Soviet presence can still be found.

All three launch complexes in this region were designed around the R-12 missile. The R-12U missile was actually used in the underground ‘Dvina’ complex, slightly different from the surface-launched R-12. This weapon was better known by its NATO designation – SS-4 Sandal – and was a 2.3 megaton, single warhead, single stage nuclear missile. It reached true international notoriety before the base in Plokstine was activated, for this was the type deployed to Cuba in the missile crisis of 1962. Coincidentally, part of the staff transferred to Cuba in the days preceding the crisis was from the same rocket regiment of the Red Army (the 79th) stationed in Plokstine. Sandal missiles from here were reportedly transferred in complete secrecy to Cuba, via the port town of Sevastopol in Crimea in that occasion.

The base remained operational until the last missile – by then obsolete – left in 1978.

The Baltics were the first republics to leave the dying Soviet Union, openly defying the military authority of neighbor Russia. After the collapse of the Union and the end of communism in Europe, these three states – which historically do not belong to Russian culture – quickly joined the NATO and European Union, to escape Russian influence as much as possible. Most Soviet military installations were shut down and abandoned, and have been for two decades an interesting destination for explorers and war historians (see this post for many examples). Later on, most sites have been slowly demolished or converted into something else. Really a few of them have been preserved for posterity.

In this post you can find photographs from the Cold War Museum now open in the former ‘Dvina’ site of Plokstine, from a visit in 2017. Close to the bottom, you can find a few further photographs from a previous visit made by appointment in 2009, before the site was selected for renovation – these may be more appealing for Soviet-aura lovers!

Sights

What can be visited today is all in the area of the old ‘Dvina’ complex. The complex is mainly composed of four interred silos, covered by heavy steel & concrete bulged covers, placed on the four corners of a square. These gigantic caps are the most prominent components of the site from the outside. Today, an observation deck has been erected on the south of the area. From there, you can appreciate the distinctive plan of the ‘Dvina’ complex, with an access road terminating in a loop touching all four armored silo covers.

The weight of each cover is told to be around 100 tonnes, as it was armored to withstand a nuclear explosion. The covers would be pulled sideward with a sled mechanism, to open the silos before launch. Unmovable missile launch complexes, like the ‘Dvina’ site in Plokstine, were easy and attractive targets for western weapons, thus requiring a very strong defense barrier. Similar considerations led the design of the Titan missile sites in the US, which albeit more powerful and capable of a greater range, are roughly from the same era (see this post).

To get near the silos or get access to the museum, you need to pay a ticket and join a guided tour. The visit includes a tour of the Cold War Museum, which has been prepared inside the rooms of the former control center. The tour will start from the visitor center, a new modern building. You will soon go through a specimen of the original fences which ran around the ‘Dvina’ complex, and which included barbed wire and high-voltage electrified lines. Close by, you can find traces of original unarmored constructions, likely service buildings. The missile site was operated by more than 300 troops stationing in a number of smaller centers in the area around the complex.

The guide will lead you along a walk around the surface part of the complex, where you can see the construction of the caps from very close. The metal part is very rusty, but the concrete cover has been refurbished and looks like new – a pretty unusual sight, for connoisseurs of Soviet military relics!

Access to the underground missile service and control center is via a small metal door, right in the middle of the square formed by the four silos.

A few rooms in the control center today host the exhibitions of the Cold War Museum. A room displays a quick time-line of the Cold War, since the end of WWII to the end of the USSR. In the adjoining rooms you can find propaganda items

Another room is about defense against nuclear threat. This is interesting, with many artifacts like dosimeters and medical tools, plus easily readable instructions of ‘dos and don’ts’ in case of nuclear attack.

Another room is about the evolution of weapons over the Cold War decades, with original material from the time, including heavier tactical weapons.

The exhibition is modern, small but not superficial, and may appeal to any public, including children. Besides the exhibits, you can appreciate the relatively small size of all rooms and connecting corridors in the former control center.

As you are driven next to the missile operation part, you can find a scale model of the ‘Dvina’ complex and a cut-out of a R-12U silo, together with a map of the relatively few missile sites in Lithuania – from the map, it can be argued that, for some reason, many more sites were prepared in nearby Latvia.

Resting quarters for the troops and a communication station with original electronic gear have been reconstructed based on original footage and pics. Communication with the military headquarters was clearly an essential task – it was the only way an order to launch could be issued – and the serviceman on duty was responsible for assuring a permanent link with the chain of command. In other words, he was instructed not to leave his headphones under any circumstances, during a several hours-long shift!

On the sides of the corridors you can see holes for the extensive network of cables and pipes. Further on, you meet the most ‘hardware’ part of the exhibition. First, the original diesel-fueled power generator has been refurbished and is standing in its original room. The underground complex was designed not only to withstand a nuclear blast, but also to provide shelter for all servicemen for several days following an attack. This meant air filters, food, water, technical supplies and of course electrical power, were all essential assets. Oil for the generator was stored in a container in an adjoining room.

Finally, you get access to one of the four silos. You need to go through a tight door opened on the wall of the concrete structure of the control center. Writings in Cyrillic can be spotted on the walls in this area. From there, you will see the cylindrical shape of the metal structure of the silo from the side. This metal canister is really big, the ‘Dvina’ silos featured a much greater diameter than the SS-4 missile they were built for. This was somewhat different from their US counterpart (see this post), where the missile diameter fits the size of the silo without much margin.

You can get access to the silo via the original hatch, cut in the metal wall close to the rim on top of the silo, just beneath the external cap. Going through this hatch is incredibly difficult – it is extremely narrow, much longer than the size of a human step, and tilted upwards! It is hard to understand why the Soviets built it in a size so small – this applies to the control center too, for all corridors are really narrow and the ceiling in the rooms is so low you may easily need to bend forward! For those who don’t want to try the original entry to the silo, there is now a non-original door cut in the side of the canister.

The inside of the silo can be observed from an original service deck, immediately under the external cover. From here you can clearly appreciate the size of the construction – the missile was more than 70 ft long, and sat here in a vertical position. The SS-4 was among the first missiles to make use of a storable liquid propellant, which allowed it to stay in almost-launch-ready conditions for a prolonged time, if resting in a silo. Nonetheless, the time for opening the armored caps was about 30 minutes, which meant this was not exactly quick to launch. The understructure of the armored caps can be clearly appreciated from inside the silo.

Photographs Before Restoration Works – Ghost Base

When I visited this site for the first time in 2009, it was open only by appointment. Unfortunately, I had only a compact camera at the time, and the very low light inside plus a rainy day outside, meant I could take only a few acceptable pictures.

However, they provide an idea of the state of the ‘Dvina’ complex before it was decided to reconfigure it as a museum.

As you can see, the armored silo caps were in a worse shape than today, yet not heavily damaged. The barbed wire fence around the four silos was probably original Soviet.

Inside, the control rooms were basically empty, except for some communist emblems and flags. Green wall paint and Cyrillic writings could be found even at the time, so what you see today is likely original. The generator, whilst in bad shape, was there.

The silo could be accessed only via the original hatch, and except for the partial darkness, its appearance is similar today.

It is out of doubt that the ‘Soviet ghost aura’ of the base was somewhat lost in the restoration process, yet credit must be given to the effort of the local government in preserving a rare and relevant trace of military history through an expensive restoration process.

Getting there and moving around

The Cold War Museum (Šaltojo karo muziejus in the local idiom) is located in the Zemaitija National Park, northwestern Lithuania, east of lake Plateliai. Access is via the road 2302. The place is totally accessible and well advertised locally. Visiting the outside of the armored caps and inside is possible only with a guided tour, offered in many languages including English, and lasting about 50 minutes. No fee is required for climbing on top of the observation deck. Full information through the official website here.

Base Tuono – Cold War Surface-To-Air Missiles in Italy

Just like West Germany, post-WWII Italy found itself on the border with a communist dictatorship, Marshal Tito’s Yugoslavia. Even though Tito and the government of the USSR were never close friends, from the viewpoint of the western alliances Yugoslavia represented a potential threat.

This mistrust was also a result of the aggressive policy Yugoslavia had adopted against Italy after WWII, imposing the cession of a piece of traditionally Italian territory in the northeast part of the country as a war compensation. This had triggered a significant migration of the local population, who was trying to escape from communism to mainland Italy and abroad. This added to the bitterness of the Italian-Yugoslavian relationship, to the point that the new border was not formally settled until the 1970s.

Italy was among the founding members of anti-communist NATO in 1949. This meant the chance to take part in a coordinated defense effort against the eastern bloc. Among the tangible results of this cooperation was the adoption of American war material, including aircraft and, as soon as they became a reliable war asset, missiles.

Considering air defense, besides a number of manned aircraft, the airspace of western Europe was protected by two defensive lines of surface-to-air missiles (SAM) extending roughly from the North Sea to the area around Venice on the Mediterranean. This was studied especially to counteract bombing raids carried out by a great number of enemy bombers simultaneously attacking from the east. This huge defense system was based on the US-designed Nike and Hawk missile platforms, and deployment started in the late 1950s.

SAM installations in Italy comprised the low to intermediate altitude Hawks, with a quick reaction capacity against low-level intruders. These were managed by the local Army. High altitude Nike-Ajax and later Nike-Hercules missiles were operated by the Italian Air Force against high-altitude targets, typically bombers. New dedicated groups were established since 1959, trained in the US to work with the new missile platform. At its height, the Nike force in Italy counted on 16 such groups, apparently corresponding to as many launch bases.

Concerning the effectiveness of the Nike defense line, it soon became obsolete, in the sense that a significant part of the strategic deterrent was transferred to ICBMs by both the NATO countries and the USSR. As a result, SAM defensive lines conceived against aircraft intrusion and low-level attacks would turn out more useful than the high-altitude and high-yield Nike-Hercules. As a matter of fact, all Nike platforms were deactivated in Italy and everywhere in Europe by the early 1980s, well before the end of communism in Europe.

Following deactivation, most bases, stripped of all hardware of any value, were simply locked up and abandoned. In Germany very few traces of this extensive system remain to this day (see this post). Together with the US, Italy is possibly the only country where this fragment of military history is documented through the active preservation of one of the former SAM launch bases.

The Nike-Hercules base preserved in Italy is called ‘Base Tuono’ – ‘tuono’ meaning ‘thunder’ in Italian language – and was operated between 1966 and 1977. It is in a gorgeous mountainous setting in the northeastern Alps, about an hour from the little town of Trento. After years of disrepair, a part of it has been refurbished with original material and opened as a beautiful, partly open-air museum, where you can get a lively impression of how the base would have looked like in the years of operations.

The following photographs are from a visit to ‘Base Tuono’ in Autumn 2018.

Sights

Nike batteries were composed of two connected but geographically separated areas, an integrated fire control area (IFC) and a launch control area (LCA). In the first resided the electronic aiming part, comprising all the antennas and electronic gear necessary to collimate the target, compute the expected kill point of the missile, and to track and guide the missile to that point. The launch area was composed of an array of three flat concrete pads, each supplied with a hangar for storing the missiles, gantries for putting typically three missiles at a time (per pad) in launch position, and a concrete shelter to oversee and trigger the launch sequence. An extensive description of the Nike SAM system can be found on this excellent dedicated resource website.

Due to the features of the radar guidance system, the IFC had to stay in line of sight from the LCA, and at a higher – but not excessively higher – elevation. At ‘Base Tuono’, due to the mountainous setting, the two areas are not far, yet they are not easily accessible from one another. Furthermore, what remains today of the former base is all concentrated in the launch area. One of the three original pads – ‘Alpha’ – has been preserved, where the other two – ‘Bravo’ and ‘Charlie’ – and other ancillary buildings as well, have been completely demolished, and a water basin can be found in their place. All installations and housing in the former control area on top of a local peak – Mount Toraro – have been wiped out, but you can get an impression of the original plan of this part of the base walking around on your own.

Launch Control Area

The launch pad ‘Alpha’ is the focus of the museum. Approaching from the parking, which is located close to the site of the former barracks and canteen, you can spot from the distance three Nike-Hercules missiles aligned in vertical launch position. A water basin covers a large part of the former base, as you can see from historical pictures. Launch pads ‘Bravo’ and ‘Charlie’ are totally gone, similarly to the original outer fence delimiting the large perimeter of the installation.

Getting closer to the launch pad ‘Alpha’ you can notice an array of radar antennas, which were originally in the IFC area on top of Mount Toraro. The area of the launch pad features a reconstructed inner fence, which was in place around each pad in the original base.

The pad is basically rectangular in shape, with a hangar on one side, a protection rim and the launch control bunker on two opposing sides and a free side where today you can find the ticket office.

Three missiles are placed on top of their launch gantries. The gantries are part of a sophisticated rail system, designed to allow an easy side motion of the missiles from inside the hangar to their respective launch positions outside. The missiles were stored horizontally in the hangar to the far top of the rail on trolleys. When being readied for launch, the trolleys were pushed along the rail to the launch position, where the trolley was joined to the gantry. The missiles were raised to a vertical attitude together with the trolley with the help of a lift, which was a movable part of the gantry.

While the pavement is covered in asphalt, you can see the gantries and the rail system are staying on hard concrete foundations. These are among the few remains you see in the German Nike site covered in this post.

Inside the hangar you can spot a Nike Hercules missile, with lateral cutouts to expose the inner structure. These reveal the four-canister solid-propellant booster stage, which was ignited first and was separated from the bullet-shaped second stage when exhausted. The latter features the warhead, the electromechanical rigs of the guidance system, and a single solid-propellant sustainer rocket engine. The rocket had a range of about 25 miles, and a top speed over Mach 3, making it a really remarkable piece of technology especially compared to the soviet counterparts of the time.

All around the missile in the hangar you can see inner parts of the missile itself and of the ground fire control system as well. There are also panels with the history of the base, and original warning signs and instructions painted on the inner walls of the hangar – and similarly on other walls of the base. These writings are in double language, both in Italian and English. While the base was managed by the Italian Air Force, such installations were integrated in the NATO defense line, so many procedures of the Italian Air Force were in English. Furthermore, US military staff was required on site ‘by design’ in case of operations with nuclear warheads, which the Hercules could optionally carry. Nuclear warheads were never deployed to this base though.

Further items on display around the three missiles on the open apron include an old Nike-Ajax missile, a Lockheed F-104 Starfighter – the Italian Air Force was the last in the world to retire this model from service, as late as 2004 – and two trailers aligned in a row. The trailers are the battery control trailer, or BCT, and the radar control trailer, or RCT. Both trailers were originally in the IFC area of the base, and were operated by the staff responsible for offensive operations. In the days of operation, there was always somebody on duty in the trailers.

The BCT is, roughly speaking, where targets were designated, the kill point computed and the launch sequence triggered. The most notable feature are the two computerized plotting boards used to identify the target and to define the flight trajectory of the missile. The LOPAR detection radar and the identification friend-or-foe (IFF) radar reported information to this trailer, which coordinated the attack.

In the RCT stood the operators of the TTR and TRR radars, which were responsible for keeping trace of the target and for monitoring the missile during the flight towards the designated kill point.

To the back of the two trailers, it is possible to spot the rectangular shapes of the LOPAR radar and of the smaller IFF radar. The two round-shaped antennas are the TTR and TRR radars. In many pictures they are portrayed inside a bulbous cover, conferring them a distinctive spherical shape.

The concrete bunker to the opposite side of the launch pad with respect to the trailers is a protected room for the launch section panel, which is a kind of control panel for triggering the launch sequence of the missiles. The bunker served as a shelter for the operators of the launch section, for remaining on the outside in the vicinity of the missiles during launch operations was extremely dangerous.

During the guided visit, you are given a demonstration of the launch sequence from inside the control room, which is insulated from the outside with double tight doors. The firing procedure was quite complicated. Actually, it was a direct signal traveling along a cable connection from the battery trailer that gave the go to the missiles. Yet there were redundancies for increased safety, and it was possible to trigger the entire launch sequence from within the firing section, in case communication with the BCT was lost. During normal operations, the OK from the operator of the control panel in the bunker had the function of a further go/no go safety layer for the launch.

A trailer with a panel similar to that in the bunker can be found outside. This likely represented a further redundancy, or like the F-104 it is a piece coming from somewhere else.

To the back of the bunker with the fire section panel you can find an original watchtower from a US base in northern Italy, similar to the towers originally in place around the missile base. Close by, there is a nice example of the canisters used to the transport the stages of the Nike-Hercules, as well as the crane used to assemble it. There is also a further example of the second stage of the missile.

Getting there and moving around

The ‘Alpha’ battery of the launch control area is open as a museum, called ‘Base Tuono’. It is located on the road SP143, which departs from Folgaria, a small town about 12 miles south of the regional capital town Trento. You can find clear roadsigns leading to the site from Folgaria.

The museum has opening times, visiting is generally possible on a self-guided basis. Access to the bunker and the trailers is possible only on guided tours. All information on their website (in English). Large free parking about 0.2 miles away from the entrance.

There is much to see for technically minded subjects, but the visit will be surely appealing for children too. I would recommend to allocate at least 45 minutes for the visit, and up to 2 hours if you want to take a guided tour and take all the pictures on your own. The scenery around is gorgeous, so it will be easy to combine this destination with a nature trail or with other tourist destination in the area.

Integrated Fire Control Area

This is where the radars and trailers used to stay, together with barracks and service buildings. It can be found about 2 miles south east direct line of sight from the launch pad, on top of Mount Toraro. Differently from the launch control area, this area has been demolished and sanitized. No buildings remain in place, yet some of the former foundations and platforms to anchor the trailers can still be seen.

Reaching to the top of the peak is interesting to appreciate the view of the launch site from here. Unfortunately, at the time of my visit low clouds obstructed the sight.

Getting there and moving around

Even though the wide original road to reach this part of the base still exists, for some reason access to the top of the mountain is not allowed by car. In order to get to the trailhead from the museum, you can take your car and keep going southeast along the SP143 for about 1.5 miles. As you go ahead, the road will change the name to SP92 on your nav. Soon after the road starts descending, you will find the trailhead to your right, with a horizontal obstacle and a prohibition sign for cars. You may park there. It is likely the trail to the top of Mount Toraro will be on your nav too, for it is basically a normal road. The distance to walk to the top is about 1 mile, along the former service road to the base – covered in asphalt, gently ascending, no risk of any kind.

The Border Forts of Czechoslovakia Against Nazi Germany

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

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

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

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

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

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

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

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

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

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

Map

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

Stachelberg

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

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

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

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

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

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

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

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

Getting there and moving around

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

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

Voda, Brezinka and Lom

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Getting there and moving around

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

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

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

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

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

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

Hanicka

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

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

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

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

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

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

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

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

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

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

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

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

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

Getting there and moving around

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

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

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

Bouda

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Getting there and moving around

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

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

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

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

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

Hurka

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

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

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

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

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

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

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

Getting there and moving around

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

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

Traces of the Cold War in Southwest Germany

Between the end of WWII and the collapse of the USSR in the early Nineties, Germany was caught in the middle of the confrontation between the West and the Soviet bloc. An unnatural and heavily guarded new border was established between the two adversaries, which crossed the extensive territory of todays Germany. Thanks to the presence of American, British and French military forces over the western territory of the Country, and of the Red Army to the east, with the start of the Cold War the German ‘inner border’ became a modern line of the front for this new type of confrontation (see this post).

All armies stationed there benefited from substantial resources poured by the respective governments in the setup of permanent military detachments and infrastructures. The aim for the nations involved was that of having on the spot a credible force, capable of effectively fighting an enemy army – as well as hitting the populations of neighbor Countries – in case a new war was started in Europe. In the end, an open war was never fought, yet for decades it was deemed possible, and in some crisis moments even likely (see this post).

This chapter presents pictures from five Cold-War-themed sites in southwest Germany. Photographs were taken in April 2018, and in the summer of 2020 and 2021.

Sights

With the end of the game for the communist empire and following German reunification, Russian forces withdrew from all bases in Germany – as well as from many other Countries in Europe – and so did the foreign NATO allies, with a very few exceptions. Most former military bases and military infrastructures fell in a state of disrepair, and by the years the majority were either completely wiped out or converted into something else. Nonetheless, especially in the less crowded territories of the former communist East Germany, visible traces remain from the period, in the form of – sometimes immense – abandoned airports and military bases (see this post and links therein).

Comparatively less traces of the once substantial presence of NATO forces are to be found in todays western ‘Länder’ – i.e. administrative regions – which used to be part of West Germany. Yet something of interest for Cold War ‘archaeologists’ can be found also here.

A long chain of anti-aircraft missile batteries was implemented based on the Nike missile system designed in the US, and implemented by the US Army as well as other NATO armies in West Germany. The defensive line was established in the 1950s and updated over the years, running almost parallel to the border with the communist DDR, but located pretty far from it and well within the territory of West Germany. It stretched from the North Sea to the Bodensee, on the border with Switzerland. There are some very extensive references on the web providing a complete description of the Nike defensive barrier both in the US and abroad, a very rich one here (the link should point directly to the German section).

In this chapter you can find some pictures from an exploration of an abandoned Nike Hercules site next to the town of Wurmberg, just out of Pforzheim, between Stuttgart and the French border. It used to be run directly by the US Army.

Intermediate-range ballistic missiles (IRBM) were part of the tactical plans of both the US and the Soviets in Europe. The Pershing platform, based on the homonym theater-level nuclear missile, was deployed in Germany, and placed in the inventory of both the US Army and the West German Luftwaffe. The missile was updated in several instances in the decades of the Cold War, until it was banned by the INF treaty in 1988, agreed upon by the administrations of Gorbachev and Reagan.

Among the strongpoints of the Pershing missile deployment in Europe, a huge warhead deposit was built close to the town of Waldstetten, next to Schwäbisch Gmund in southern Germany. In this chapter you will find photographs from an exploration of this mysterious site.

Furthermore, a nice collection of aircraft from both sides of the Iron Curtain can be found in the southwestern corner of the Country, next to the town of Villingen-Schwenningen – one of the few air museums in this part of Germany. Similarly, the large collections of the military museum in Stammheim, next to the town of Schweinfurt in northwestern Bavaria, and once close to the ‘Inner Border’ with the GDR, has on display substantial specimens from the Cold War era.

Finally, a special feature presented in this chapter is a group of pictures from the former airbase in Giebelstadt, south of Würzburg, Bavaria. Today a privately owned general aviation airport, this former military airbase gained a special historical significance when it was selected for the departure of secret overflights of the communist territory beyond the Iron Curtain, performed with the Lockheed U-2 in the late Fifties, by decision of president Eisenhower.

Nike Missile Battery – Wurmberg

The site in Wurmberg, east of Pforzheim, was actually Battery ‘Delta’ – i.e. the fourth – of the four missile forces managed by the the 3rd Battalion of the 71st Air Defense Artillery (ADA) regiment.

Typical Nike missile batteries were composed of two geographically separated areas. The largest was the ‘Launch area’, with missile storage facilities – sometimes reinforced underground bunkers, sometimes more usual ‘soft’ hangars – and launch pads. The other was the ‘Integrated Fire Control area’ or ‘IFC’, where all antennas and electronic equipment for target detection and missile guidance were placed. Due to the limited speed of motion of the missile guidance antennas, the distance between the launch site and the IFC had to be greater than a threshold, while the elevation of the IFC had to be somewhat above the the launch pads. These technological constraints led the choice of the sites suitable for the installation of the Nike batteries.

The site was deactivated in the Eighties, and both areas were sanitized in more instances, basically demolishing any buildings. The ‘final stage’ of the operation is likely to be underway at the time of my visit, as you can see from the pictures, where piles of gravel and moved land can be spotted all around the launch site.

Surprisingly, a feature that has come to our days virtually without any alteration is the external fence of the launch site, which runs all around the launch area and is still particularly impenetrable. Also the rounds of barbed wire on top are still there.

The exploration of the launch area is pretty straightforward. It is rectangular, basically flat and aligned along an east-western direction. Close to the eastern end,  you meet a flat area with a concrete pavement – now partly demolished – and a curved road nearby. This is where the missiles and warheads were assembled. Nike missiles could mount nuclear warheads, but apparently this was a rarely adopted option.

The next notable item to the west is a water basin, still in a very good shape. There used to be a water system all around the base. Remains of demolished buildings can be spotted around here too.

A mystery electric cable comes out of the ground on a spot. It is noteworthy that the launch area and IFC were connected by an underground cable, but I don’t think this is the one you see in the pics.

This battery had three launch sectors, bearing the little imaginative names of ‘Alpha’, ‘Bravo’ and ‘Charlie’. You can find them in a sequence, walking towards the west end of the site.

The pads of the Alpha sector, while now greatly damaged by the demolition work, are still in place with their metal covers.

There were three launch pads on each sector. The area of each sector appears unnecessarily large, but actually the missile storage hangar used to stay beyond the launch pads, occupying about half the area of each sector. Today these soft constructions have disappeared.

To the west of each sector there is a small bunker, intended for the protection of the troops working around the launch pads, in case of an attack to the battery. These bunkers are not very damaged, so they constitute a very interesting part of the site today.

The protection bunkers have two exits on the two opposite sides – so the Alpha bunker connects the Alpha and Bravo sectors, the Bravo bunker the Bravo and Charlie sectors, while the Charlie bunker connects the Charlie sector to the logistic storage area to the west end of the launch site.

The Alpha bunker is well conserved – except for some spoiling by some idiot writer. There is no camouflage paint coat outside, just some plain green paint, and the walls inside are painted in a bright crimson color. The bunker has two opposite entrances, and two corresponding corridors leading to two massive tight doors, which give access to a central protected room, insulated from the outside.

Writings in English are still there in the central room of bunker Alpha.

The launch sectors Bravo and Charlie are more damaged than Alpha.

The Bravo bunker is camouflaged, and differently from Alpha the walls inside are painted in water green. It is possible to notice how the central room was separated from the rest of the structure for blast insulation, similar to other missile sites (see this post). There is a wide slot at the level of the doors.

Further writings in English and some original linoleum pavement are still perfectly visible.

The Charlie bunker is different from the other two. The facade is wider, it is coated in a camo paint, and bears the name ‘Charlie’ above the eastern door. Inside it is very dark, possibly as a result of a fire. In the insulated room it is possible to see an original air conditioning system.

The three launch sectors are connected to the south by a wide road, from where you can appreciate the extension and state of conservation of the original fence.

The IFC area is located just north of the small town of Wurmberg, on top of a hill. Unfortunately, the former military site has been wiped out and a nothing less than a waste disposal facility has taken its place! Anyway, from this vantage point you can clearly see the launch area, roughly two miles to the west.

Getting there and moving around

Getting to the launch area is very easy. Leave the highway N.8 close to Pforzheim (the exit is 45b Pforzheim-Süd) and take for Pforzheim on Wurmberger Strasse. Take the very first road to the right and park your car there. You will see a gate open since ages and an almost unmaintained road taking straight north and climbing gently uphill. This road will take you to the official gate of the launch area in 0.4 miles. Getting in is probably prohibited, but the area is pretty remote and secluded, and I didn’t see a person around during all my stay.

The site is geographically compact, so touring may take about 2 to 2.5 hours taking all pictures, if you have planned your movements in advance. A tripod is strictly necessary for taking decent pictures inside the very dark bunkers.

The IFC area can be reached going to Wurmberg, leaving the same exit but taking the direction opposite to Pforzheim. You will soon reach central Wurmberg. Cimb along Gollmerstrasse, then along Oschelbronnerstrasse. Where the village ends and the road stops climbing you will see a field to your left and a waste disposal facility to your right – this used to be the area occupied by the IFC area. Looking west you can see the launch area and the taller buildings of Pforzheim further in the distance.

Pershing Warhead Storage Bunkers – Waldstetten

The site in Waldstetten is basically an array of warhead storage bunkers, built between 1954 and 1958 by the US Army. In 1972 these bunkers became a part of a Quick Reaction Alert site, managed by the 1st Battalion of the 41st Field Artillery Regiment, tasked with supplying the nearby storage site of the Pershing missile in Mutlangen, just north of Schwäbisch Gmund. The site saw major action in 1982, when 36 Pershing II missiles were installed in Mutlangen as an answer to the deployment by the USSR of an updated version of the excellent SS-20 Saber IRBM system.

During the Eighties the 1st Bn 41st FA was reformed more than once, until it became 2nd Bn 9th FA in 1986, only to be disbanded in 1991, following the dismantlement of the Pershing system as a consequence of the INF Treaty between the US and USSR.

It should be mentioned that whether the nuclear warheads of the Pershing missile ever made their way to this storage site is a matter of discussion. As a matter of fact, the missiles were in the nearby Mutlangen site, and their installation triggered well documented protests by the usual pacifist folks, who encountered difficulties in understanding the moves of the Reagan administration, which helped with successfully putting an end to the Cold War and to many communist dictatorships in Europe. What the bunkers in the Waldstetten site were used for is not totally evident, and it should be recalled they were built in the Fifties, before the deployment of the Pershing system.

Of the 28 bunkers originally built, 25 exist today while three have been demolished in a landslide. The site is located in the trees along two broad circular roads, once service roads. Today it is in the heart of a natural preserve, and the roads are used by MTBs and hikers, whereas the Mutlangen site has been converted into a solar power plant.

The local administration has prepared a placard with a map and a short history of the place (in German only), which I spotted only by the first bunker you meet climbing uphill along the road approaching the site from north. You can see the placard in the pics below, with the corresponding map. The position indicated with ‘Standort’ on the map is where the placard is. I suggest starting you exploration from there.

About half of the bunkers can be accessed. Except a few, they are basically indistinguishable.

Inside they are empty and very basic in shape, with just one large storage room. Other bunkers are inaccessible, and some have been converted into bat shelters.

A notable bunker is 870 (see the map in the pic), which bears on the front facade graffiti from US troops, probably veterans visiting the place in recent times after it was closed up. Today it is a bat shelter.

In 869 you can find some naive paintings, including one portraying a truck probably dating from the years of operation.

A mystery bunker is 856, which is very different from all others. It has two small entrances, apparently for humans only, and a group of small chambers ahead of the larger storage area. This has no wide entrances, suggesting it was not used for warheads nor anything similar, and a blind room to the back. Unfortunately, this bunker is also covered in indecent graffiti.

Another interesting sight, especially visible to the west of the bunker area, is the original fence of the storage site, with a number of aligned concrete posts and traces of barbed wire. The line of the fence is shown also on the map.

Getting there and moving around

The storage bunkers are located on top of a hill, and some climbing is required to reach the bunker area. The place is not fenced, and there are multiple access points from all directions. I personally parked at the end of Dreifaltigkeitsstrasse in Waldstetten and accessed the site from the west. After touring it, I came back passing by the placard mentioned above. The road is steeper on that side of the hill, but starting from the placard may ease your exploration.

Please note that the on most part of the site the cell phone coverage was very weak, with no access to internet data. I strongly suggest downloading your maps before being on site.

The place is secluded and the bunkers are much overlooked by the locals, who keep on the main track and just cross the area – you will probably move around undisturbed if you walk in and around the bunkers.

Due to some amount of mild hiking required, a complete tour of all bunkers may take about 3 hours, including time for pictures.

Internationales Luftfahrt-Museum – Villingen-Schwenningen

This small air museum is composed of three parts.

The first is a single hangar, stacked with smaller aircraft and a helicopter, plus memorabilia and parts of aircraft of diverse proveniences and ages, including German machines from WWII, and later from both sides of the Iron Curtain.

The main part is a grassy apron with an open air collection. Here you can see aircraft of American make in the colors of the West German Luftwaffe, including an F-86 Sabre and F-104 Starfighter.

British aircraft are represented by an English Electric Canberra and a DeHavilland Vampire of the Swiss Air Force.

Other models from western Countries include an Italian Fiat G-91 reconnaissance aircraft and a German Dornier Alpha Jet trainer.

Models from the Soviet world include an Antonov An-2 biplane, which can also be boarded, and a Yakovlev Yak-18, bearing a post-Soviet Russian flag and registration markings.

Probably the star of the show, a well restored Polish-built MiG-15 is presented in the markings of the Red Army.

The third part of the museum is a series of restoration hangars, where a number of aircraft are being restored, whereas some replicas are being assembled, possibly partly from original parts. These include a Messerschmitt Me-262 Schwalbe, and a Dornier Do-335 Pfiel, of which only one original exemplar exists in Washingtong, DC – definitely a rare sight.

Getting there and moving around

The museum, located on the side of a local touristic airport, is easily reachable in Spittelbronner Weg 78, 78056 Villingen-Schwenningen, just on the eastern border of the beautiful Schwarzwald region. Website with full information here.

A Travel Guide to COLD WAR SITES in EAST GERMANY

Second Edition - 2024

DON'T LEAVE IT AT HOME! AVAILABLE in PAPERBACK or KINDLE from your national Amazon store!

The museum in Stammheim, northwestern Bavaria, stands out as one of the largest and best preserved military collections in Germany, especially concerning the two World Wars and the Cold War. The museum is composed of a set of large adjoining hangars, and an open-air part. The hangars are rich in dioramas, built around real weapons (both heavy and light), tanks, as well as rigs, uniforms and dresses from the corresponding ages.

The first hangar is centered on WWII. Here a large central diorama represents a scene from the advance of US forces on German territory. A group of civilians reacts welcoming the American forces with white flags, whereas some armed civilian guards and some German soldiers keep a more cautious attitude.

Among the original US vehicles is a light tank, starring in the movie ‘The Monuments Men’ besides actor George Clooney. A German Goliath self-propelled drone-tank is on display in this scene.

Two house facades imitating traditional German architecture complete this central diorama.

In the same hall, more dioramas show for instance a German anti-aircraft battery, with a four-barrel gun and a searchlight. Range-finding rigs are also on display.

To the far end of the same hall, a Soviet T-34 and a Sherman can be found, besides self-propelled cannons and more vehicles set in smaller scenes.

In a lateral passage, scenes from the African theater of WWII are displayed. These include vehicles and weapons with a distinctive desert camo coat. Another diorama displays a school in Germany from the same period, with young men involved in light anti-aircraft defense.

Scenes from pre-WWII and from WWI are presented in yet another, smaller hall. Field artillery pieces from WWI are clearly discernible from more modern ones. A field kitchenette from the time is also on display.

Classical display cases feature many interesting items, including military uniforms from WWI and WWII, military decorations, air navigation charts and flight instruments.

The Cold War is covered in the last two hangars. Here field guns, mortars and armored vehicles mainly from the Federal Republic and from the German Democratic Republic – some of them still working – are put on display, side by side.

The exhibition in this part is complimented by numerous flags and smaller pieces of military material, including communication gear, water mines, transport vehicles, a military Trabant.

Part of the show is an ex-DDR early MiG-21. This can be climbed (not boarded), providing a nice view of the ensemble.

The museum is close to Schweinfurt, geographically next to the border with the former GDR. A reconstruction of the Inner Border impenetrable fence (see this post), with original signs and plaques, is duly on display.

The outside part of the museum displays a few heavy armored vehicles from WWI, WWII and the Cold War. They include a rusty, US-made M26 Pershing tank from WWII, a Federal Germany Gepard anti-aircraft self-propelled battery from the Cold War, and more.

Visible from a distance are a set of US-made surface-to-air missiles, distinctive silhouettes from the Cold War age. These include a Nike Hercules surface to air missile. Surface-to-surface platforms include a venerable and pretty rare Matador early cruise missile. This grandparent of modern cruise missiles features a distinctive swept-back wing, and a booster underneath the fuselage to the back.

The nose cone of a Pershing (possibly) is on display, together with a rare Lance missile, a surface-to-surface missile from the 1960s-70s, in the inventory of the Federal Republic in those years. The plaque on the launcher witnesses the Canadian origin of the single-missile wheeled rack, built by Orenda.

Behind the missiles, aircraft on display are a Soviet designed Antonov An-2 biplane, and a US designed Republic F-84 Thunderstreak, in the colors of the Luftwaffe of Federal Germany.

All in all, this wonderful collection has much to offer for everybody with an interest in the military history of Germany since WWI to the Cold War era. The museum sets up reunions of enthusiasts, and special days with tank movements and live displays.

Getting there and moving around

The Stammheim am Main museum is located 7 miles south of Schweinfurt, a major center in the area, and about 12 miles northeast of beautiful Würzburg. It can be conveniently reached when traveling between the two, right on the bank of the Main river. The exact location is along the intercity road SW1, on the crossing with Maintalstrasse in the village of Kolitzheim. Parking right ahead of the entrance. Small restaurant on site. Since the museum is stuffed with tons of interesting items, even though compact in size, visiting may easily take more than 2 hours for an interested subject.

Former US Airbase, Giebelstadt

The now sleepy general aviation airfield in Giebelstadt has been a rather active military airbase for many decades. A Luftwaffe fighter base in WWII, it was among the first airbases to host the new Messerschmitt Me-262 jet fighter. In 1945 it fell in the hands of American forces, who intermittently used it for various temporary deployments and flight operations over the immediate post-WWII years. The early Cold War era and the 1950s were a new period of intensive use. The runway was lengthened, and more modern facilities for stationing troops and aircraft were built anew, in place of older and damaged German ones from the Nazi era. Powerful, cutting-edge radar installations were put in place, due to the proximity with the East German border. With the transition to fast jets, the proximity of the airfield to the border was actually too much, so that interceptors could not scramble in time from Giebelstadt, in case of an enemy attack from beyond the Iron Curtain. However, this would be an advantage for reconnaissance missions, launched during the Eisenhower administration, starting in 1956.

Giebelstadt was one of the few bases for the balloons of Project Genetrix. That was a first, partly successful attempt to gather intelligence through unmanned overflights of the USSR. In the same years, Giebelstadt was intended as the main operative base for the CIA Lockheed U-2s, to be used for a more risky – since manned – but much more effective way to collect photo and signal intelligence.

The actual deployment started in 1956, with some delay due to the need to prepare the airfield for operation of the one-of-a-kind Lockheed U-2. The latter flew in the meanwhile from Wiesbaden, where the headquarter of US military in Germany was at that time. This was not much liked by the US intelligence community, since the latter city was more crowded than the small country village of Giebelstadt, and this exposed highly secretive U-2 operations to a higher risk of espionage.

Missions carried out by the U-2 were of basically two types. The first was relatively risky ELINT missions along the border with the USSR, where defenses were stimulated without entering the enemy airspace, to obtain precious information on the reaction capability and the enemy anti-aircraft barrier, including the position of radar sites, etc. The second mission type was high-risk ELINT/PHOTINT missions, or ‘overflights’, where Soviet airspace was actually penetrated. In the latter case, the U-2 made use of its superior altitude and range performance to carry out long missions above the defenses of the USSR. As known, the development of high-performing SAMs, reaching up to the cruising altitude of the U-2 meant it was not invulnerable any more after 1960. This put an end to overflights. However, a total of 24 mostly successful overflight missions were carried out between 1956 and 1960, each of them specifically studied and approved with the direct involvement of president Eisenhower.

Besides missions along the border, or over satellite countries of the Eastern Bloc (still considered a high risk, but not as high as a direct overflight of the USSR), a single overflight of the USSR was actually flown from Giebelstadt. This was mission No. 2040, flown on October 13th, 1957, with Hervey S. Stockman at the controls. A report from this mission can be found on a CIA document here.

Following the end of the U-2-based intelligence missions, Giebelstadt was ceded to the US Army in the years of Kennedy. The Army used it as a huge base for helicopter operations well into the third millennium – the base was deactivated and returned to Federal Germany only in 2006.

Today, the now private airport can be barely neared without triggering security service. However, even a quick look along the fence will reveal clear traces of the US military tenancy. From hangars to fences, to softer constructions north of the airfield, everything is much US military standard.

The runway – huge for todays single-prop and glider activities! – can be seen clearly from the south and from the eastern end.

Antenna arrays and a now oversize control tower are other witnesses of the past military activity.

Getting there and moving around

Giebelstadt airport can be conveniently reached along road N.19, about 8 miles south of Würzburg. Unfortunately, despite the road passing right besides the airport, there are very few options for stopping close to the fence with a car on this fast road, and similarly on the road going along the southern fence of the airport, taking east to Mönchsmühle nearby. However, the eastern runway head can be approached from the latter. Just turn north towards the base in the vicinity of the general aviation hangars in the southeastern corner of the airport. The road is a dead end, and you will likely trigger some inspection by people inside the fence, so not much to worry about if you stay outside.

Another part which can be toured is the former administrative part/barracks to the northeast. This can be entered driving along the northern side of the airport. This area has been taken over by private companies, and you might trigger some inspection by the respective security agencies. They are rather friendly though, so again, not much to worry about if you take picture staying in your car.

Forts of the Maginot Line

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

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

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

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

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

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

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

Ouvrage de la Ferté

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

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

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

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

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

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

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

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

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

Getting there and moving around

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

Ouvrage Simserhof

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

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

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

Getting there and moving around

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

Ouvrage du Four à Chaux

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

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

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

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

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

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

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

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

Getting there and moving around

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

Casemate Esch

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

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

Getting there and moving around

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

Abri de Hatten

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

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

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

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

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

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

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

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

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

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

Getting there and moving around

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

Fort de Mutzig – Feste Kaiser Wilhelm II

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

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

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

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

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

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

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

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

Getting there and moving around

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

The Salpa Line – Finland’s Anti-Soviet Barrier

Possibly one of the world’s best preserved military installations from WWII, Finland’s Salpa Line – the name ‘salpa’ meaning ‘latch’ – is a defense line composed of about 700 reinforced concrete bunkers with anti-tank cannons and machine-guns, more than 200 miles of anti-tank obstacles, roughly another 200 miles of trenches pointed with over 1200 machine gun nests, 500 artillery positions and more than 700 quartering dugouts. All this, and everything necessary to operate this enormous war machine, including hundreds of miles of new roads, electric cables, dams, telephone lines, etc., was built to defend the border between Finland and the Soviet Union.

History – in brief

The Winter War

Finland enjoyed the rigors of WWII since 1939, when following the Ribbentrov-Molotov pact between Nazi Germany and the USSR, it was agreed off the records that this Country should enter the sphere of influence of Stalin’s communist dictatorship. Finding no other way to submit the Finns, Soviet troops attacked Finland from the East all along their common border, from the Gulf of Finland up north to the Barents Sea, at the end of November, 1939.

This rarely told chapter of WWII is known in Finland as the Winter War. Finland, which on a September 1939 map looked somewhat larger to the east than it looks today, fought fiercely against a numerically much superior enemy, which at the time was not engaged on any other major front. Despite the very difficult situation, with no help – except limited arm supply – from the outside, the motivated Finnish Army led by General Mannerheim recorded some marked victories especially in the central sector of the border, and managed to avoid a complete defeat. This unexpected military resistance, and the promise of Britain and France to support Finland had the war continued further, led the USSR to agree upon a peace treaty as soon as mid March 1940, basically crystallizing the military situation reached at the time. As a result, the border moved west by about 60 miles in southern Finland, with the loss of the Karelian Isthmus and the city of Vyborg, the access to lake Ladoga, Finland’s Eastern Karelia – simply known as Karelia in Russia – and a large territory in Lapland, mostly uninhabited. Finally, the peninsula and port town of Hanko, 70 miles west of Helsinki, was ceded to the USSR for 30 years.

Building the Salpa Line

It was at the end of the Winter War that Finland’s government, following the suggestion of General Mannerheim, took the decision to built the Salpa Line, to defend the new border against any possible attack of the Soviets.

Construction work on this impressive system, made not only of a chain of forts, dugouts and barracks, but also of an extensive network of communication and transport infrastructures, was carried out mainly between spring 1940 and summer 1941, Finland’s so-called Inter-War Period. Up to 35’000 workers – mainly civilians from private companies – were involved, roughly bringing the defense line to completion by mid 1941. The line was designed primarily to protect the most populated and easily accessible part of the Country in the south, and a major concentration of strong points was erected along todays border line with Russia, between the Gulf of Finland and the town of Joensuu.

At the same time, a smaller branch of the Salpa Line was erected on a much smaller scale on the new border with the USSR, along a 3 miles line cutting through the Hanko peninsula.

The Continuation War

In the period between the end of the Winter War and the surprise offensive of Germany against the USSR in June 1941, the Nazi Wehrmacht had successfully annexed Denmark and Norway to the Third Reich, thus becoming a neighbor state for Finland, just like the Soviet Union. In the process, Finland allowed Germany to transport troops and material to northern Norway moving on national land, and receiving arms in return. In the same period Hitler refused to endorse further Soviet attacks against Finland, thus further narrowing the diplomatic distance between Germany and Finland, which nonetheless managed to remain independent throughout WWII.

When the war broke out between the Soviet Union and Nazi Germany, Finland took the initiative and attacked the USSR, soon regaining control of basically all territories lost in the Winter War, including the port of Hanko, by the end of 1941. The German Wehrmacht attacked the Soviet port town of Murmansk and the nearby area, rich of natural resources, from the northernmost Finnish region of Lapland.

Due to the quick movement of the front line back east, the Salpa Line saw basically no fight, and was maintained until the end of the war with the Soviets in 1944 as a rear defense line.

This phase is known as Continuation War, and quickly turned into a war of attrition along a stable border line. This equilibrium was cracked when the military situation started to get worse for Germany after the defeat of Stalingrad in early 1943. After months of negotiations with the USSR to put an end to the conflict, following a massive Soviet attack on the Karelian Isthmus in August 1944 and the second loss of Vyborg, an armistice was signed in September between Finland and the Soviet Union, in favor of the latter. It restored the border line as it was at the end of the Winter War and imposed a long-term lease of Porkkala – a peninsula on the Gulf of Finland 30 miles west of Helsinki – instead of Hanko. Also included were heavy war reparations and the neutrality of Finland with respect to further Soviet campaigns. Plus the immediate expulsion of all German forces from Finnish territory.

Nonetheless, differently from almost any other Country touched by the Red Army in the events of WWII, Finland managed to retain its complete independence from Stalin’s communist empire, and part of the credit goes to the existence of the Salpa Line, a major deterrent against any further Soviet military aggression.

The request to severe any contact with Germany led to the final chapter of WWII for Finland, the Lapland War, when the Armies of Finland and the USSR attacked the Wehrmacht in the north of the Country, starting a campaign lasting months until the final defeat of Germany, causing the total destruction of many villages and of the town of Rovaniemi.

Sights

As a result of the course of events, Finland’s fortified line of defense did not see any direct military action. This spared it for posterity as a notable example of military technology of the Forties. Of course, as war technology evolved rapidly soon after WWII, the Salpa Line rapidly became obsolete and was largely abandoned. Most dugouts, soft construction works as well as most wooden, unreinforced positions have been reclaimed by nature. Only traces of the trench lines exist today, except in those spots where they have been explicitly preserved for the public.

Heavy positions are a totally different matter. Except for a few mainly in the northern part of the Country, blown up by the Soviets in the months of the Lapland War to help expelling Nazi troops from the Finnish territory, most bunkers and strong points are still there, basically intact. The majority has been abandoned, but due to a demolition work being an economy nonsense, they can still be seen today.

At least two small groups of bunkers in the very south of the Country have been turned into top-level museums on local military history, with a modern visitor center, guided tours and so on. Some bunkers, like in Joensuu, can be visited as little local museums. A good number of the reinforced concrete installations have been left open for interested visitors, stripped of any dangerous military hardware, sometimes even partly refurbished, and in most cases they can be freely accessed – provided you find them. Some are included as checkpoints along official multi-miles hiking trails, which are among Finland’s top tourist attractions. More often, either you know where they are in advance or you will hardly find them in the wilderness.

For reaching most of the non-advertised bunkers of the Salpa Line, you need to drive to very secluded locations along unprepared roads. If you like this kind of archeology, this adds much to the fun!

The good news is that Finland considers the Salpa Line a historical landmark as a whole, thus any damage or alteration is strictly prohibited and severely prosecuted. So you are not to see your search frustrated by finding a bunker covered in graffiti or used as a shelter by ravers or drug addicts – as it is often the case with the much similar Atlantic Wall in France. This is also because except for a few cases the superstite installations are located far from any urban center. By the way, Finland boasts one of the Europe’s lowest crime rates, so exploration is made potentially dangerous only because of intrinsic – rusty barbed wire, mimetic manholes, narrow passages, total darkness … – or natural causes – badgers, boars and bears!

In the following a description of a few notable points of interest along the Salpa Line is presented. The list is extremely far from complete, as it would take at least several months of dedicated work to explore the Line in its entirety! Yet this selection provides a good specimen of all basic types of sight you can find along the line. Photographs were taken during a visit in summer 2017.

Map

The following Google map was created based on the very useful information provided on this website, which is an excellent starting point for any exploration of the line. Basic info on the corresponding Salpa Line sites are provided on it almost one by one, and pinpointed on a map, but apparently there is no comprehensive map on that website. The website is also Flash-based and totally ‘iPhone unfriendly’ – it simply doesn’t load on my iPhone 6S. So I can’t take any credit except for having put together all points and having made them smartphone accessible. The red signals refer to points pictorially described in this article. The area of Hanko and the museums of Mikkeli are not covered in the map, whereas some sites will be described in another chapter.


The list below is ordered roughly from the south to the north.

Virolahti Bunker Museum, Virolahti

This site – Virolahden Bunkkerimuseum in Finnish – is among the southernmost of the Salpa Line, conveniently located on the busy E18 connecting Helsinki to St.Petersburg. The museum is a good starting point for getting an idea of the features of the line. There is a visitor center with a modern setup, where you can see a collection of light weapons from both the Finnish and Soviet sides – actually many Soviet weapons left behind by the retreating Red Army at the beginning of the Continuation War were later reused by Finland’s Army. Much information is provided in a synthetic and readable way – both in Finnish and English – on the construction of the line and about the war history of Finland, with a focus of what happened along the sector of the front closer to the Gulf of Finland.

The outside part is organized along a short trail in the trees. The first main stop is a reconstructed trench, with an example of a spherical soft concrete bunker type, conceived to cover dugouts. Nearby you can see two small heavy metal turrets. These were designed to be partly interred, to form an armored machine gun nest. The thickness of the metal construction is stunning! There is also a line of stones put in the terrain, a typical anti-tank obstacle to be found in many sites of the Salpa Line.

A German-made Pak-40, 7.5 cm anti-tank cannon in perfect condition is presented in a reconstructed open-top field fortification.

Nearby, you can access a perfect example of an anti-tank bunker. Three main areas are featured in this type of bunker. First, a relatively large living and sleeping area, with bunk beds for troops, a big stove, a water sink, and an air pump. Second, a firing room with a 45 mm anti-tank gun permanently installed, with the barrel leaning out of a suitably designed blind window. Third, a firing room with a machine gun, with the barrel leaning out of an open slot cut through the thick concrete wall of the bunker. Both the cannon and machine gun fire basically in the same direction, from the front facade of the bunker, whereas the only way in is through a sealed door to the back.

The bunker is provided with a metal observation turret on top, accessible through a ladder mounted in a very narrow vertical tunnel with a sealed door.

Another original bunker you can visit in Virolahti is a quartering bunker, capable of sleeping 40 people. The construction is similar to the large living area of the previous bunker, but this is larger.

Examples of original trenches which have not been refurbished can be spotted as smooth grooves in the ground between the reinforced bunkers. Finally, there is also a collection of cannons – some of them very old – and machine guns, from the USSR, Finland, Sweden, France and Italy. Heavy cannons from various ages were provided by France at the time of the Winter War, and put in place along the Salpa Line in more points, so they can be spotted pretty often in Finnish museums.

Not a part of the museum, it may be interesting to check out what the frontier with Russia looks like today. You can come pretty close to the border zone driving south of E18, along the unpaved Kurkelantie road going to the small villages of Reinikkala and Kurkela. There is a well signed respect zone instituted along the border line, which cannot be accessed without all necessary papers and permits.

Nonetheless, the striped posts marking the border can be spotted with a zoom lens from the distance. I can’t guess whether in Soviet times the border did look like this, or instead it used to appear less penetrable. Of course it may be just a matter of appearance – when I was there, I personally didn’t even think to try coming close to Russia without an explicit permission, so I don’t know what may happen should you try to get near the border by entering the respect zone by foot!

The Virolahti site can be visited in something less or something more than 1h, depending on your level of interest. It is flat and easy to tour, with a large free parking nearby. Website here.

Salpa Line Museum, Miehikkälä

This is probably the biggest exhibition on the Salpa Line, and the most visited also. The visitor center proposes a series of itineraries for touring the site on a self-guided base. The highlights are anti-tank and machine gun bunkers, a plane spotting wooden turret, trenches of various types, cannons and more. Together with Virolahti (above), it is surely a place to be if you want to capture at a glance what the Salpe Line is all about.

The Miehikkälä site is unique in its own respect due to the morphology of the territory, with a rocky cliff prospecting on an area of wavy land. The two main armored positions with an anti-tank gun and a machine gun are atypical, dug deeply in the rock, accessible from the top of the cliff, with the barrels leaning out at the level of the surrounding terrain. The bunker with the anti-tank gun features an observation/firing turret directly accessible from the firing room through a very long vertical passage. In the living quarters there is a collection of rifles.

The bunker with the machine firing chamber presents preserved sleeping and living quarters, and an observation turret.

Ahead of the rocky cliff you can find two armored turrets like in Virolahti, and an example of the most typical anti-tank barrier of the Salpa Line, made of aligned big rocks put in the ground. This is a distinctive feature of the Salpa Line, and following the rocks may help to find the location of more secluded bunkers in other sites.

Another interesting item is an old Soviet T-34 tank with the corresponding shelter.

To the back of the cliff you can find a German-made Pak-40 anti-tank cannon in an open-top field fortification. Looking in the direction of the barrel, you can see a long grove aligned with it. This is a tank trap, where the tank was forced to slow down trying to cross the grove right on the line of fire of the anti-tank gun.

In a second part of the site it is possible to find a group of rare concrete trenches, mostly similar to WWI constructions you can find in northern France (see this post), a housing bunker with a water reservoir on top and a standard anti-tank/machine gun bunker. These could be seen only from the outside when I visited.

The museum is not difficult to find, and there is a large free parking on site. The visit may take from less than 1 hour to more than 2 hours, based on your interest. While not difficult to tour for an average physical condition, you’d better go prepared to climb many stairs, move along narrow passages and walk short trails going steeply uphill. Website here.

Hostikka Site

The Hostikka site, deep in the countryside north of Miehikkälä, is composed of a handful of bunkers scattered a few miles apart along the roads in the municipality bearing this name. On each site there is a complete description in Finnish and English, and a map. Most sites can be freely accessed, a few are normally closed and can be opened on request, usually visiting with a ranger. A comprehensive map in Finnish can be found here.

From the south, item B186 is a massive anti-tank/machine gun bunker which is normally closed. The guns can cover a flat field ahead of the facade of the bunker.

A bare 300 ft north along the unpaved main road you meet B182, a machine gun bunker which can be toured freely. You can recognize the sleeping quarters and the observation tower. Climbing on top, you can appreciate the mimetic installation of the bulbous top of the armored tower. There is also what appears to be a firing hole close to the main sealed entrance.

All armored doors are still there, together with an extensive piping system.

Driving north for about 0.3 miles crossing the small village of Hostikka, you can find another site, with a preserved trench system, a machine gun and quartering bunker, open but unfortunately severely flooded, and item B166, a huge cave. This is not the only cave excavated in the rock along the Salpa Line. This multi-entry cave was intended for sheltering 80 people and providing access to open-top cannon/machine-gun dugouts. It was never finished, it is uninsulated and very wet.

The road going to Kirppu passes by items B150 and B132, standard anti-tank/machine gun bunkers. They are usually closed, but can be climbed and walked around.

All these bunkers unwind along a north-south direction, and are easily accessible parking nearby each site. Visiting may take 15 to 30 minutes for each open site, especially if you want to take pictures inside, less for closed bunkers where you may want to have a walk round. For inside pictures a tripod is mandatory, and a torchlight highly recommended.

Lusikkovuoren Cave

This cave can be reached driving for less than a mile on a secondary road departing eastwards from 3842 in Suo-Anttila. The cave is usually closed and sometimes used for public exhibitions or performances – a very suggestive location! -, yet the place deserves to be seen also from the outside. There are actually two neighbor entrances to the cave, which has been carved deep into the rock at the base of a cliff. The cave, intended to be used as a logistic interchange point, a headquarter and a weapons storage, was never completed. There are draining holes and a concrete pavement inside.

Hidden in the trees, far from any village, from the outside the cave really looks like a location from ‘The Lord of the Rings’!

Askola Site

The Askola site can be spotted while driving roughly halfway between Luumäki and Lappeenranta, along a busy road called Lappeenrannantie, next to the shore of lake Kivijärvi. There is a parking area just ahead of it. Heading straight to the big bunker you see from the road, you can find a map of the site. There is an uncommon concentration of armored positions in a small area between this trail head and the newly built highway N.6 to the south.

Despite the majority of the bunkers being normally unaccessible, there are some interesting uncommon sights here. The first is a reinforced dugout, where one of the bulky armored metal turrets you can see in the museums of Virolahti and Miehikkälä is interred in its intended working position. The turret can be accessed from behind and below, and a machine gun is mounted inside.

Furthermore, there are at least two original tank turrets recycled as reinforced firing positions. These turrets are apparently from BT-7 Soviet tanks, probably lost to the Finnish Army during the Winter War or the Continuation War.

More standard bunkers and dugouts can be found, but in some cases they can be barely neared due to wild vegetation.

About 0.8 miles to the west along the Lappeenrannantie road, you can find a small concrete dam – actually it lies in the courtyard of a private house… This is part of a system made to control the water level in the lake for military purposes.

Moving eastwards towards Lappeenranta, in the small village of Rutola it is possible to find another machine gun/housing concrete bunker, with an anti-tank barrier on the shore of the lake. This also lies on private land.

A visit to this site may take a 1-2 hours or more, depending on the level of detail and your ability to move around.

Syysphoja and Puumala Site

Along the beautiful scenic road 62 going from Imatra to Mikkeli it is possible to find two easily accessible forts of the Salpa Line. The first is located on Salpalinjantie road, departing north from the main road east of the village of Syyspohja. The facade of this well deceived anti-tank/machine gun fort, dug in a pile of land and hardly visible from the distance, is partly covered with stones. There are also partly refurbished dugouts and wooden obstacles, plus a long line of anti-tank stones.

West of the village along Töntintie road – very narrow and unprepared – it is possible to find a small Soviet monument to war prisoners interned in a local prison camp.

Another preserved bunker can be found right in the center of the nice village of Puumala, along road Pappilantie. The bunker is basically unaccessible, but very easy to walk around. In a receptacle besides the main entrance there is also a Soviet anti-tank gun, probably captured by the Finnish army.

General Mannerheim Headquarters and Communication Bunker

Among the highlights of the lively town of Mikkeli, you can visit here the preserved headquarters of the Finnish Army. The office of General Mannerheim and other top-ranking military staff, plus a fully equipped ‘op-center’, were installed in a local children school. Today a few rooms, including one with many original maps and Mannerheim’s personal office, are the ‘main course’ of the museum, and can be visited.

There are also informative panels, many pictures and some memorabilia belonging to General Mannerheim.

Almost cross the the road from the entrance of the headquarters, you can find another strictly related museum. It is a cave were the communication central of the headquarters used to be and work during WWII. This ensured an uninterrupted communication link not only with the Salpa Line but also with all positions on the line of the front. A part of the cave has been carefully refurbished to resemble what it looked like in the years of operation, including much communication hardware from the time, whereas another part has been left empty.

Both museums can be visited according to the respective timetables (website here for the headquarters, here for the cave). Total visiting time for both attractions is about 1.5 hours.

Raikuu Site

Two Salpa Line sites are located close to the small village of Raikuu, both easily reachable driving on reasonably prepared, unpaved roads.

The first is a massive and pretty rare heavy artillery position. There used to be four such positions scattered in the nearby area, two equipped with 299 mm mortars, two with 152 mm naval cannons. This is the only partly refurbished position. The base for the central revolving pinion where the cannon was anchored can be clearly seen, as well as rooms for the cartridges and for artillery troops.

The second is a group of three reinforced concrete bunkers, maintained to a very good condition and different from one another. The first two are a machine gun and an anti-tank cannon bunker respectively. The military equipment has been taken away, but the different shape of the barrel hole and the supporting structure for the machine gun or for the anti-tank cannon make them easily distinguishable. The machine gun bunkers bears traces of camouflage on the front facade.

Some of the original ventilation pipelines are still there, and clear traces of the wooden structures can be seen on the walls.

The last bunker is partly accessible from behind descending along a steep staircase. This bunker is leaning on the side of a rock, and is well deceived in the bushes.

The site is completed by an anti-tank wall of unusual construction, made of smaller stones put together to a very big overall thickness.

This site is very nice to visit, it is pretty remote so probably you will stay alone and undisturbed. Total time for visiting both including transfer by car may be 1.5 hours if you want to take pictures, or much less if you just want to have a look around.

Joensuu Bunker Museum, Joensuu

The museum in Joensuu is somewhat smaller than those in Virolahti and Miehikkälä (above), and when I visited it was already closed for the season – in mid-August! The good news is that in case you find it closed, you will miss only a visit to the inside of the bunker, pretty standard and similar to those you can see also elsewhere, whereas the outside can be toured for free at any time.

The first sights are two Model 1877, 90 mm French field cannons provided in a number during the Winter War and extensively used in the following years. Close by there are some steel turrets for protecting dugouts to form armored machine gun nests. These turrets, similar to those you may see also in some other Salpa Line sites, were supplied in very limited numbers and were produced in two shapes – you find both here – and three different weights. Those presented here are all intermediate-weight exemplars, weighing more than 5 and almost 8 tonnes respectively for the round shaped and the two-lobed model. The thickness is incredible, and these turrets could withstand a direct hit of a 45 mm anti-tank gun!

On the perimeter there is a Soviet 45 mm anti-tank cannon in a wooden open-top field fortification.

There are two concrete bunkers, put side by side on a promontory. One is equipped with both an anti-tank and a machine gun, the other only with a machine gun.

There are also well preserved dugouts and a line of rocky anti-tank obstacles.

The site is easy to access, with free parking, and compact in size, so less than 1 hour is needed for a visit if the inside is not accessible. Some opening info here.

Huhmarisvaara Artillery Position

Many cannons of French design can be found scattered over the Finnish territory. Except relatively few offered by the French at the beginning of WWII before France was conquered by the German Wehrmacht, the majority are actually Russian cannons from before the the Revolution. When turmoil started to spread in Russia in 1917 leading to the anticipate end of WWI, Finland took the initiative and declared independence from the agonizing empire. As a result, many weapons and military stuff stationed over the territory of the newly constituted Nation were recycled by the Finnish Army.

Many such cannons were later to be placed in the fortifications of the Salpa Line. In Huhmarisvaara, roughly 13 miles north of Joensuu, a concrete fortification for a number of cannons was prepared on a vantage position overlooking a local lake. One of the three Russian-made Model 1892, 152 mm cannons remaining in Finland can still be found in this location.

Vanntajankannas Site

The northern part of the front saw an active participation of the German Wehrmacht in the years of the Continuation War. Possibly one of the northernmost heavy installations of the Salpa Line was located about 5 miles southeast of the town of Kuusamo, close to the administrative border with the Lapland district. The Germans – with the forces of the Organization Todt – built also a railway line about 85 miles long in a north-south direction, with the northern terminal in Kuusamo. The railway helped to supply the army groups operating locally.

The history of this installation, today preserved as an open-air museum with a well maintained walking trail about 3 miles long, is a bit different from others. Soon after the armistice which drove Finland out of the war with the USSR, the German forces, which had to be expelled from the Country, started retreating north towards occupied Norway. They found shelter in the fortifications of the Vanntajankannas site for a few weeks, before loosing them to the Red Army. Soviet soldiers were forced to leave by the end of 1944 in accordance with the armistice agreement, but they blew up every hardware in the Vanntajankannas area before retreating to the USSR.

What can be seen here is what remains of some big concrete bunkers, of the types you can find elsewhere along the Salpa Line. The remains of the bunkers are scattered along the trail. Close to the trailhead there are also scant remains of the local railway station along the German-built line going to Kuusamo.

The anti-tank line of stones is still clearly visible. In many points the trenches, open-top passages and soft machine gun nests have been refurbished to look like the early Forties when they were built.

In the most remote part of the site it is possible to spot remains of the original concrete preparation station, used to supply the construction works, and a small concrete sauna for workers and troops – not really welcoming in these days!

This site is very nice not only for war history but also for the beautiful landscape, with incredible colors. You can also experience a walk over the marshes typical of this region of Finland. The trail is easy, there is a small free parking nearby the trailhead. I would recommend about 1-1.5 hours to enjoy the hiking trail and taking pictures of both the landscape,  the destroyed forts and preserved trenches.

Harparskog Line, Hanko Peninsula

The southern branch of the Salpa Line, also known as Harparskog Line, is composed of a group of bunkers concentrated in the small area around the village of Harparskog – on the Hanko peninsula -, which found itself on the border with the USSR for the first time following the peace treaty ending the Winter War. The annexation of Estonia to the USSR and the control of the Hanko peninsula gave the Soviets the control of the Gulf of Finland, which culminated in Leningrad to the east.

Hanko was evacuated by the Soviets in late 1941 during the victorious phase of the Continuation War.

Similarly to the rest of the Salpa Line, the smaller line in Harparskog featured all types of heavy concrete bunkers, plus dugouts, field fortifications and trenches. Today you can find at least one of the bunkers preserved as a local small museum, plus plenty of barely maintained but mainly accessible bunkers, stripped of most military hardware but still in a very good condition.

The bunker museum was closed when I visited, so here you have a view of the outside only.

Some of the accessible bunkers are aligned along an unpaved road towards the northern shore of the peninsula, north of the village. A commemoration stone with an explanatory panel clearly marks the trailhead.

Besides some more standard bunkers, it is possible to find here a big assembly composed by at least two large bunkers excavated in the stone. The passages leading to the entrances are carved deep in a local cliff, resulting in a very suggestive fort, a mix of natural and artificial defensive positions. Inside this fort it is possible to see also an original stove, ventilation ducts and an air pump.

Further on you can find an anti-tank line, and also a larger deposit and a cave – unfortunately closed.

Exploring this area can be very rewarding, due to the tranquil location and the beautiful, wild natural landscape.

There is much more to see in the area, and for a complete exploration I would suggest about 5-6 hours. The sector to cover is not large and for some parts you can move with a car, but the concentration of material is unusually high and well preserved. If you elect to concentrate only on a part of the line, the necessary time may drop to 1-2 hours for getting a good idea of the main features of this site and taking some good pictures inside. Don’t forget a tripod and a torchlight, for it’s totally dark inside most bunkers, and you should wear a pair of appropriate shoes, for there are mud deposits on the floor and the terrain around the bunkers is totally uneven.

Hanko Front Museum, Hanko

A museum on the vicissitudes of the Hanko peninsula in the years 1940-41 has been established and recently refurbished. It will show up along the main road connecting Harparskog and Hanko, around 2 miles from Harparskog.

The inside part presents an interesting descriptions of the timeline and facts of the Soviet occupation. There are many interesting artifacts from the time, including everyday hardware, light weapons, propaganda leaflets in Russian, maps and many historic photographs. It is interesting to note that the weapons put in place by the Soviets included huge railway cannons, definitely easier to move compared to fixed installations of similar size.

There is also a room with a collection of heavier weapons.

On the outside there are some reconstructed trenches, a Soviet 45 mm anti-tank gun in a reconstructed field fortification, and some other weapons, especially water mines. Active archeology work is going on in the area, and some recent findings, like pieces of artillery and parts of tanks, could be seen when I visited. A short trail in the trees reveals some dugouts and allows to explore the area nearby the former border. Finally there is a 152 mm coastal gun, reportedly the world’s last of the type with this field mounting.
