Bornholm – Military History of a Contended Danish Island

The small island of Bornholm is today a popular destination for vacation time. Especially in the summer, the small and picturesque towns along the coast, as well as the curvy roads unwinding over the gentle slopes in the countryside, become increasingly crowded with cars, motorbikes, campers and bicycles – however, without reaching the point where a tourist who is looking for relaxation may feel uncomfortable.

The quiet and relaxed aura of this enjoyable piece of land, halfway between the German-Polish coast and that of Sweden – and nonetheless part of Denmark – hides a history pointed of battles and turmoil, lasting from the early era of the vikings until the Cold War.

Quick historical facts

Between the medieval times and the 17th century, the island was often seized by the Hanseatic League, binding together coastal towns in the Baltic and protecting trading routes. During the 17th century, Sweden became a major player in the area, and wars between Denmark and Sweden meant the island changing landlord more than once, with the locals always playing militarily in favor of a union with Denmark, to an extent made possible by their own forces, yet meeting with final success.

A largely forgotten war between Britain and Denmark, taking place in the years of total confusion brought about by Napoleon’s endeavors all over Europe, meant that Bornholm was attacked by the British fleet in more instance between 1808 and 1810, basically without any success.

World War II

The invasion of Denmark by the Third Reich and the capitulation of the Danish government, militarily unable to counter the irresistible march of Hitler’s military forces in April 1940, resulted in Bornholm being occupied by the Germans. The local Danish commander annotated the order not to resist the German take-over with disappointment, feeling that a firmer military response to the invaders was indeed possible. The island was fairly well organized and armed against an air-launched invasion.

The capitulation of Denmark without engaging in a military struggle allowed to obtain less harsh conditions from the occupants, including a limited independent military activity for the first years of WWII. However, a strong anti-German feeling fueled the growth of a resistance movement, including locally in Bornholm.

Similar to what happened to the Danish mainland (see this post), the military planners of the Third Reich included Bornholm in the coastal defense structure on the outer border of the newly acquired German territory – the so-called Atlantic Wall. In particular, construction of a fortress for four 38 cm cannons started on the south-eastern corner of the island, in Dueodde (similar to that in Hanstholm, Denmark, of Vara, Norway). The very efficient Organisation Todt had the first two emplacement largely complete by April 1941. By the attack on the Soviet Union in June 1941 however, and with the rapid expansion of the Third Reich to the east, the fortress in Dueodde was deemed of little use. In the event, construction works never reached completion.

Further significant war-related construction projects on Bornholm included observation posts and several radar stations (Würzburg and Freya types), which could profit from the location of the island on the route taken by bomber groups on their way back to Britain from raids over Berlin or the surrounding region. The proximity with respect to the facility for the development of experimental weapons at Peenemünde (see here) made of Borhnolm a natural place for the installation of measuring equipment. Furthermore, the main coastal town of Rønne – still today the largest center of the island, where most of the commercial and ferry sea traffic goes through – was largely employed as a base for the Kriegsmarine. Actually, more than 600 different German submarine units called this port during the war years, about one half of the entire German submarine fleet!

Diplomatic relations between the Third Reich and Denmark deteriorated rapidly in August 1943, when the Germans – now at a turning point of the war – launched operation Safari, trying to capture all assets of whatever military value from Denmark, thus also destroying its military capability. As a response, Denmark scuttled 32 of its own vessels, and sent a handful to Swedish or to even more distant friendly ports. In Borhnolm all Danish troops were disarmed and taken away from the island.

Somewhat paradoxically, the most tragic events of the war struck Borhnolm at the very end, when the island found itself off the coast of Poland, now taken over by the Soviet Red Army advancing from the east towards Berlin (see this post). As the fear of defeat and imprisonment grew among the ranks of Third Reich forces, following the heavy losses on the eastern front in Spring 1945, many German troops reached Bornholm to prepare for an escape further west, or north to neutral Sweden. This presence was noticed by Soviet intelligence, who intercepted communications mentioning several thousands of German military troops on the island – their actual number has been estimated at around 20’000 by May 1945. The war officially ended in Denmark on May 5th, 1945. However, at that time the chain of command and the communication system in the Third Reich had collapsed, and the local German commanders on Bornholm still retained the order to repel the Soviets with any possible means, without permission to surrender. As a result, the Soviets bombed the island twice, severely damaging Rønne and the port town of Nexø, unharmed up to that point, on May 7th and 8th, 1945.

Soviet Occupation

Following the two Soviet bombing raids, a group of six Soviet torpedo boats sailed from Kolberg, Poland (now Kolobrzeg, see this post), landed and reclaimed control of the island of Bornholm on April 9th, 1945. At that time, about 16’000 German troops and refugees were still on the island, trying to flee to the West or to Sweden by any possible means. Reportedly 700 boats of any kind were involved in this desperate evacuation operation, and about 5’000 Germans (military and civilian) had fled by sea just the day before the Soviet landing.

The anti-German resistance movement on Bornholm joined forces with the Soviets, trying to search for trapped German troops and prevent their escape to the West. The airfield in Rønne was captured on May 9th in one of these joint actions – specifically stopping a German aircraft already taxiing for take-off, after some others had already successfully got airborne! These operations went on until May 20th, and due to the very significant number of German troops still on site, they required drafting people in the Soviet-backed group of ‘freedom fighters’, which afterwards remained the only official local para-military group on the island, besides the Red Army (conversely, members of the the original voluntary resistance movement soon returned to their pre-war civilian occupation).

The Soviet presence on Bornholm constituted a potentially explosive problem. The agreement at Yalta between the US, Britain and the USSR in February 1945, months before the actual capitulation of the Third Reich, had defined that Denmark would remain independent, and specifically not within the Soviet-controlled territories in Europe. The British government, at that time still led by Churchill, was extremely worried by the Soviet capture of Bornholm, and after unofficially questioning the Soviets, the answer was even more appalling – according to Soviet diplomats, the island had to stay under Soviet control indefinitely, through the support of a military contingent of 9’000, soon to reach those already on site!

This led to the beginning of a peculiar page in the history of Bornholm, and of the diplomatic relations between the USSR and the West, which would soon get worse on a global scale, leading to the Cold War. Relations between the local Danish government and the Soviets were generally good at an official level, thanks to the skills of the local leading figure on the Danish side, von Stemann. To keep the public eye on this unsolved issue, he managed to organize an official visit of the Crown Princess of Denmark, who met the Soviet top staff on Bornholm. The day-by-day coexistence with the Soviets was less idyllic, with increasing incidents due to the misconduct of the bored Soviet troops stationed on the island, and the growing discontent among the locals. Uncertainty about Soviet plans fostered fear over a possible long-term occupation.

Finally in December 1945, Britain officially questioned the Soviet government about the case of Bornholm, and Molotov answered that the Soviet Union did not intend to have any permanent base in Denmark (as per the Yalta accords), yet the island was to be retained by the USSR as a guarantee, due to the presence of British troops on the Danish mainland.

The Danish government reacted preparing to retake full control of its own territory, correspondingly asking all foreign troops – from any nation – out of its borders. In March 1946 it was announced that the Soviet troops would leave the island of Bornholm, as Denmark prepared to install its own military forces back on it. In good order, the Soviets actually left the island, the last ship departing Rønne on April 5th, 1946.

The Cold War

Denmark joined NATO as a founding member in 1949, the result of the action of the then prime minister Hans Hedtoft, a former member of the resistance in Denmark, who had got a clear insight of the line of action followed by the Soviet Union, at that time still led by Stalin.

The support given by Denmark to NATO was not obvious for that country, since the proximity to the Eastern Bloc – especially Bornholm, geographically located close to the (by then) Soviet-controlled Polish coast – made Denmark extremely vulnerable and militarily untenable in case of a potential Soviet attack. The policy adopted by the Danish government over the decades of the Cold War in support of NATO was sincere but always carefully calibrated, to reduce the risk of Soviet intervention, which would possibly result in an extremely dangerous escalation.

Consequently, no international NATO base nor any nuclear warhead was ever permanently based in Denmark. Yet highly defended coastal strongholds were established, which can still be seen today (see this post).

Bornholm hit the headlines in the early phase of the Cold War, when the first-ever jet-propelled fighter from beyond the Iron Curtain defected to the West. This happened on March 5th, 1953, the very same day of Stalin’s death. The Polish pilot, 21 years old Franciszek Jarecki, had departed Slupsk airbase in northern Poland on a training mission, when he suddenly left his group and flew as fast and low as he could to Rønne, where he safely landed his aircraft, asking for asylum. The aircraft was a MiG-15, and that was the first time this new type of aircraft, which played havoc against propeller-driven machines in the early phase of the Korean War, could be inspected by Western powers.

The case was treated very carefully from a diplomatic standpoint by Denmark, to avoid provoking a violent reaction on the Soviet side. A technical inspection was carried out in a well-coordinated, highly secretive mission set up by the British and the US, ending with the restitution of the reassembled machine to Poland. Finally, the pilot was granted asylum in the US, where he had a remarkable military career (his flight suit from the defection mission ending up in the Smithsonian collection, at Udvar-Hazy Center, close to Dulles airport in Washington, D.C.). This topic is well covered in the excellent book ‘The secret MiGs of Bornholm‘ by Dick van der Aart (see the bookshop section).

Jarecki’s escape was not an isolated case, since in 1953 and 1956 two more Polish fighter pilots successfully landed (or crash-landed) their aircraft on Bornholm (while another made it all the way to Sweden). Then the Soviets had Polish fighter units relocated further south, where Bornholm was out of range, and took over control of the northernmost bases.

Defection to Borhnolm by air on a jet fighter was rare compared to the overall cases of people reaching Bornholm to flee either communist Poland or the GDR, similarly close to the island. For all the years of the Cold War, Bornholm constituted the goal of dozens of escape attempts, some of them successful, carried out mostly by sea.

The location well within the Soviet area of influence was exploited with the construction of a prominent intelligence base by Denmark, to the advantage of NATO forces. This was again in the Dueodde. The base was very effective and was updated to keep up with upgrades in electronic communication technology over the years until the end of the Cold War. It was later kept in service, and shut off only in 2012.

A visit to Bornholm today will likely be for relaxation and for enjoying this nice country. However, for those with an interest for its peculiar history there are some very interesting collections and rare sites to visit. They allow to retrace in particular the rich military history of the island, without much effort and with great satisfaction for either researchers or the general public. This post covers five of them, four of which are museums. They were all visited in the summer of 2024, and all photographs were taken in that occasion.

Sights

Bornholm’s Defence Museum, Rønne

A good place to start the exploration of the military history of Bornholm, the Defence Museum (Bornholms Forsvarsmuseum in the local idiom) is located to the south of the town center of Rønne, the busiest seaport and the capital city of the island.

The museum is hosted in two old military buildings, including the local kastellet, a massive tower with a round base, built for coastal defense.

The collection is housed in the courtyard and on the two levels of the first building. For the relatively little area it covers, this collection is extremely rich and informative, with panels covering in depth some specific events, offered in multiple languages including English.

On the ground floor, an interesting exhibition on the evolution of the artillery in Bornholm starts with a display of very old cannons – including possibly the oldest preserved exemplars of some types – and insignia dating from the wars against Sweden.

Then more modern exemplars from the 19th century, and reaching to an American type 105 from WWII, employed on Bornholm in the Cold War period, allow to follow the evolution of this type of weapon.

For more curious visitors, little artifacts interspersed between the larger exhibits on display add much value to the collection. Training material for anti-aircraft artillery from the WWII era, including down-scaled fake aircraft targets, as well as various types of grenades and shells employed with the artillery pieces stationed on the island can be found on display between the big guns on the ground floor.

An original German aiming device has been positioned such to be still usable – you can see outside through the optical system. Note the eagle and swastika marking on the label.

A particularly interesting item, not easy to find in a museum, is a complete launching device for the Stinger missile. This type of ground-to-air anti-aircraft missile, albeit rather rudimentary compared to other offensive missile platforms, has turned out very effective in actual war scenarios, especially against slow-moving aircraft or helicopters. The compact launchpad, operable by a single gunner, features two launching tubes. Aiming is via a visor, and the trigger is placed on two pistol-like grips.

Many radio transmitters and receivers, including a sizable console with stacks mostly made in the US (look at the labels and tags!), are on display together with a rare computer, a Compucorp 625 Mark II, a standalone machine which was employed from the late 1970s to run a software for ballistic computations.

On the top floor of the same building, an exhibition covering some specific military episodes from the 19th century serves as an introduction to the rich collection of memorabilia from WWII and the Cold War.

Decorations from the Third Reich, as well as insignia, uniforms and personal everyday items belonging to the Wehrmacht troops, or to some specific people in the German staff living on the island, are on display, in most cases along with explanatory panels telling their peculiar stories.

Unusual items include a table with mottoes in German, an embroidered napkin with emblems from the winning powers of WWII.

As said in the introduction, Bornholm found itself on the trajectory of allied bombers returning from raids on today’s northeastern Germany (including Berlin). In more instances, bombers damaged by flak fire or by German fighter aircraft, hence unable to make their way home, were forced to crash-land on Bornholm. The detailed history of two of these bombers and their corresponding crews is told in a dedicated set of display cases, showing even the track followed by each of the crew members as they tried to flee Bornholm (occupied by the Germans). Some interesting memorabilia items are on display from those episodes, including personal belongings of the crew members, and cash notes in diverse currencies, with their names written on them. These notes were given specifically to crew members, to help them in case of landing in a foreign country in Europe.

From the same era is a perfectly preserved Enigma machine. This is presented together with a detailed story, which could be retraced by war historians in Bornholm. Actually, this specific machine was made in 1937 and largely employed on the Eastern front in the actions against the Soviet Union. When German troops were fleeing the northern coast of Poland and Germany in the last days of the war (May 1945), the machine arrived to Bornholm, where it was little employed, since the chain of command of the German Army had collapsed by that time. The machine was ditched in the water by the surrendering troops, but it was soon to be found, taken to a private house, and largely forgotten afterwards. Finally, it was donated to the museum decades later.

Another unusual display is about the relics of German experimental weapons landing in Bornholm, and the espionage operations related to their find. Due to the proximity with the island of Usedom and the research center of Wehrner von Braun in Peenemünde, launches from the polygon where V-1 and V-2 were being tested could be spotted sometimes from Bornholm. Actually, early exemplars of a Fieseler Fi-103, aka V-1, first stranded on Bornholm in July and August 1943. They were first discovered by two local Danish citizens belonging to the police, who took quick sketches and pictures, and passed them to the British through the anti-German resistance links. These turned out to be the first photographs of that new weapon to reach the western Allies. The two were captured and imprisoned by the German occupants, but eventually they managed to flee to Sweden.

Some relics of the V-1 crashed on Bornholm are on display, as well as memorabilia items belonging to the two Danes who found the relic. The latter include a British decoration presented for their service.

Additionally, interesting pictures show the contrail of a V-2 photographed over Bornholm, and the picture of another V-2 crashed in Sweden!

Further remains from the era include gauges from the cockpit of German fighter aircraft, captured by the Soviets as they were trying to takeoff from Bornholm and escape, and a ribbon from the ill-fated German passenger ship Wilhelm Gustloff. She was sank by a Soviet submarine roughly 60 miles east of Bornholm in January 1945, while enroute to mainland Germany from former possessions of the Third Reich in nowadays Poland, lost to the advancing Red Army. Losses are estimated in the range of 10’000, making this largely forgotten episode by far the worst-ever naval disaster in history.

Another rich section documents the presence of the Soviets on the island. Artifacts on display range from flags and direction signs for the stationing troops, written in Russian, to many personal items left behind by the Soviets.

Typical propaganda posters are on display as well, similar to more official and non-public items, like transcripts of communications between the local Danish and Soviet commanders from the age of the Soviet occupation of Bornholm in 1945-46.

Many evocative pictures are on display from that time as well, and similarly from the Cold War. Among them, pictures of the Polish MiGs landed on Bornholm, of the many ELINT and COMINT centers put on Bornholm during the decades of the Cold War (including the tower in Nexø, see here), and copy of the Soviet attack plan in case of war against NATO.

A final chapter documented in this nice museum is the service of the Danish Armed Forces within the UN in Cyprus. Tasked with border surveillance between the two regions on the island, Danish forces were involved in action – with some casualties – at the time of the Turkish attack in 1970. They only left the island in the early 1990s.

The kastellet is today mostly empty, and once inside, it is possible to appreciate the original architecture of this bastion, which saw action against the many attempts by foreign attackers to land on Bornholm.

On the outside and in a small depot on the side of the inner courtyard, further items are on display. Propellers from the WWII aircraft crashed in the area represent both the German Luftwaffe (Do-17 bomber) and the Western Allies (B-24 and Halifax bombers).

A Chaffee-type small tank and two armored vehicles are on display, together with naval guns, radar antennas, land robots and artillery aiming gear.

A peculiar sight is one of the observation turrets originally scattered on the territory of the island, for spotting aircraft or other flying stuff and promptly report it.

On display are also sea mines, sonobuoys, radar scopes and parts of torpedoes, some of them interesting Soviet models, likely recovered from the Baltic Sea during the Cold War.

Ahead of the entrance to the museum, a memorial stone has been put more recently by an association of veterans.

Getting there and visiting

The museum is located close to Rønne downtown, from where it can be reached with a short walk (about .3 miles south from the central touristic area). The address is Arsenalvej 8 – 3700 Rønne. There is a little parking area on site. The museum is professionally run, and it has its own dedicated website here (also available in English).

Visiting is strongly recommended as a first stop for an exploration of the military history of Bornholm. For war buffs, WWII and Cold War historians, this place has much in store, and a visit may easily take 2 hours. Less is required for a more basic visit, made easy also by the compactness of the display.

Bornholm’s Museum, Rønne

Bornholm’s Museum is the main facility dedicated to the history of the island. Located in a former hospital, you can immediately notice the presence of a bombing raid shelter in the courtyard. This is an original relic from WWII.

The museum takes all floors of a small building, and it is dedicated to the history of the island in all its aspects, and with artifacts from all ages, including Roman coins and viking accessories.

Of particular interest from the time of the vikings is a collection of golden plates. They are smaller than a human fingernail, and decorated with human figures and other subjects. Plus, they are really many! They are of special interest also due to the fact that nobody knows what they are. Archaeologists found them mostly on Bornholm, and in a much lower quantity elsewhere in Scandinavia.

Fast forward to the 20th century, the museum has on display interesting memorabilia from WWII and from the era of the Soviet occupation.

Among them are original decorations, documents and photographs, from both the German and Soviet sides.

From the early Cold War period, a small piece from Jarecki’s MiG-15 is preserved in a display case, with a picture of President Eisenhower receiving at the White House the first pilot defecting from Eastern Europe (apparently, a young John F. Kennedy appears to stand behind them).

Shop signs and indication signs in Russian, the original working desk of the Danish governor of the island at the time of the Soviet occupation, and everyday working tools belonging to the Soviet staff are among the displays in this museum.

A – perhaps – non-permanent exhibition is dedicated to the Soviets on the island, including the two air bombing raids they carried out in the closing days of WWII, which caused much destruction.

An interesting exhibition on the Cold War in Bornholm examines it from different perspectives. Among them, it is shown how preparations for a nuclear attack included the institution of a civil defense system, similar to most western Countries.

Similarly, the conspicuous wave of defections, of both military staff and civilians, from beyond the Iron Curtain to Bornholm is fully documented. Being located relatively close to the GDR and Poland, Bornholm was a natural target destination for those trying to leave the Baltic coast by sea. On display are documents of seamen asking for asylum, as well as a small dinghy employed for a successful escape attempt. A rather impressive full list of the successful and unsuccessful escape attempts towards Bornholm from the communist world is provided.

In another part of the museum, dedicated to everyday items and business activities, it is possible to find toys and other common tools from the Cold War era, as well as beautiful models of several vessels in service at that time – as well as today.

Getting there and visiting

The museum is one of the major attractions in Rønne, the capital city of the island. It is located within the perimeter of the historical center of the town, and you will be probably visiting it if you are interested in any aspect of the history of Bornholm. The address is Sankt Mortens Gade 29 – 3700 Rønne.

For those with an interest for the military history of the 20th century, the collection of this museum makes for a nice complement to that to be found in the Defence Museum (see above).

For a complete visit, 1 to 2 hours are likely enough. Less than 1 hour is needed if you are mostly interested to the WWII and Cold War part, including the nice exhibition on the Soviet presence.

The museum has regular opening times and a fully documented website here (also available in English).

Bornholm’s Tower, Nexø

The tower is an authentic relic from the Cold War. The intelligence site in Dueodde (close to the major town of Nexø, itself close to the southeastern corner of Bornholm) was originally established in 1958, in the facilities of an old lighthouse from 1876, which is still standing besides the new tower.

The task was that of intercepting communications from Soviet channels, primarily to the aim of knowing of any potentially offensive maneuver against Denmark or NATO in advance. The geographical location of Bornholm made it ideal for installing such a plant, since this territory is significantly farther east than the Danish mainland, hence closer to the Eastern Bloc and the Soviet Union.

Soon after the take over of the lighthouse by the Danish intelligence and the installation of the first technical gear, continuous improvement started around that facility, leading to the construction of a dedicated tower, which stood until the mid 1980s, and was extensively employed for gathering useful intelligence. Among the most notable information obtained in favor of NATO forces were the reports witnessing the preparation of an attack by the Warsaw Pact forces on Czechoslovakia, at the time of Dubcek’s attempted reformation of the communist system in 1968 – an invasion which eventually took place, tragically putting an end to a new political course in that Country.

The relevance of the site in Dueodde in the panorama of NATO intelligence is further shown by the decision to substantially upgrade the technical installation, demolishing the existing infrastructure and building anew a more modern and massive tower in 1986.

The new tower was operated continuously until 2012, when the installation was finally shut down, and the facility was partly demolished and sold. It is since then privately owned, and it has now reopened for visitors.

A visit allows to explore the foundations of the tower, where cables and pipelines – including compressed air and coolant fluid – can still be seen. Compressed air was employed for keeping in shape the special ‘shells’ where the technical stuff used to be put.

These shells were arranged hanging vertically from the concrete tower, which is the only part remaining today (the shells are gone, you can see two of the original platforms in the courtyard, close to the original cooling station). Coolant fluid was employed for the big servers which hosted and processed data. A wind monitoring cabinet – made in USA – can be found at the ground level of the tower.

By taking the original elevator, it is possible to climb to the top, where the view ranges in all directions, and allows to see the beautiful white dunes for which this area is mostly famous.

Inside the facility, mostly empty today, it is possible to see some remnants of the server rooms. Most of the empty rooms have been employed for a display of electronic cabinets and communication gear. A reconstruction of some of original technical rooms has been attempted, and the display is completed with historical pictures of the site.

Server rooms are among the preserved original parts of the tower.

Further rooms host displays related at large to WWII and the Cold War.

An interesting addition to the visit is an original MiG-15, presented in the colors of the Polish Air Force, and resembling those which fled from Poland to Bornholm, at the commands of brave early Cold War defectors. Photographs and copies of newspapers documenting those episodes are on display.

Interestingly, what appears to be a control surface or the part of a wing of an authentic Soviet aircraft can be seen on the side of the display, likely only provisionally.

Scattered along the walls in the exhibition are original pictures, with close-ups of intercepted aircraft from the Soviet bloc.

Getting there and visiting

The tower (Bornholmertarnet in the local idiom) is located close to the white dunes of the strand of Dueodde, on the very southeastern tip of the island, about 4 miles south of the major town of Nexø. The exact formal address is Strandmarksvejen 2 – 3730 Nexø. Large parking on site.

Visiting may take about 1 hour for the interested visitor. The tower can be climbed to the top with an elevator. Visiting the facility and exhibitions does not take much, since most rooms are basically empty.

The official website of this installation is here (multiple translations available).

Bornholm’s Technical Collection, Allinge

This incredible museum has been constituted through the merge of several private collections. In most cases they are very specialized selections of technical items. These range from tractors to airport vehicles, from pocket lighters to radios, from personal computers to naval radar scopes, and much more!

Besides well-stuffed collections, which strike for their size and range, there are also some specialties, like unusual items – typically relics or one-of-a-kind exemplars. Especially the latter include some items from the Cold War chapter of the history of Bornholm.

Actually, possibly the biggest item on display is a SAAB Draken aircraft. This excellent Swedish-made attack aircraft used to fly in the colors of the Danish Air Force (see this post). The exemplar on display comes with some of the accessories, including wing pods, the parachute for brake assistance, etc.

Close by the Draken, it is possible to find several aviation-related displays, like jet engines, optical gear, radar-receiving consoles. There is also the map of the scenic flights offered from an airport which does not exist any more, and which used to be close to the northern coast of the island (the only airport is today that in Rønne).

One of the jet engines looks like an evidence from an aircraft accident, involving a Learjet business jet crash-landed on Bornholm.

Not far from the Draken, another rare aircraft on display is a SAI KZIII, designed and manufactured in Denmark in 1946.

Further finds in the museum are a stop light, which was employed for stopping road traffic on local roads close to the runway, when an aircraft in need of a shallow approach path was landing in Rønne, and the doors originally in an airport building, with stickers of flight associations from all over the world.

A military trailer with radio communication gear is on display, as well as an old truck, which happens to be the very same truck seen boarded by young Soviet soldiers, at the time of the Soviet occupation of Bornholm!

A little collection is made of GDR-made items.

A small room is dedicated to marine detection gear and the corresponding scopes.

Bulky elements on display include a one-of-a-kind locally assembled truck, a monster roadworks machine made in the Third Reich and which never returned to Germany, and trucks for removing snow from the road. They have two engines, one moving the truck, the other moving the spool. The arrangement is rather involved, with an articulated (angled!) shaft carrying mechanical power from the engine to the spool.

Airport gear includes a SAAB car with a runway friction tester in the back, and a truck for spreading anti-ice fluid.

Other rich hi-tech collections include one with radio receivers, another with cameras and video-recorders.

Even one centered on personal computer consoles can be found.

The collection of tractors on display is really impressive, with machines coming from diverse nations and makers.

Other parts of the museum are basically old shops moved in, and in some cases with fully working machinery (like the blacksmith).

The list of collections is really huge! There is surely something for everybody on display.

Getting there and visiting

The museum can be found in the countryside, on the road 159 connecting Rønne to Allinge-Sandvig, one of the biggest settlements on the northern coast, about 1.5 miles from the latter. The exact address is Borrelyngvej 48, 3770 Allinge-Sandvig. Large parking on the premises.

The museum is very peculiar, it features rich collections and it is run by knowledgeable people who are willing to provide descriptions and information also in English. A visit may appeal to everybody including children, and not only to war historians. However, it is duly listed here especially for the war- and aviation-related collections in it. A visit to the entire museum may easily take about 2 hours, especially when talking with the locals. Much less is needed for a quick look at just some parts of it.

The website can be found here.

Soviet War Cemetery, Allinge-Sandvig

Even though Stalin’s USSR finally withdrew from the occupied territory of Bornholm, the conquer of the island by the Soviets in 1945-46 meant the construction of a Soviet war cemetery, similar to those to be found scattered on the territory of the former countries of the Eastern bloc.

A very unassuming and rather intimate monument was inaugurated close to the local Danish graveyard in Allinge-Sandvig. By agreement with the local government, the cemetery is still maintained today.

A central obelisk, with prominent emblems and writings in both Russian and Danish, is placed ahead of a large memorial stone, with the names of fallen Soviet soldiers on it.

Getting there and visiting

The cemetery can be conveniently reached uphill of the village of Allinge-Sandvig. The exact address is Pilegade 18A, 3770 Allinge-Sandvig. Parking is possible on the road in the immediate vicinity of the cemetery. The site is open-air and not fenced, therefore it can be accessed 24/7. Visiting may take 15 minutes.

German coastal gun site, Dueodde

The coastal guns in Dueodde, close to the southeastern corner of the island and the Cold War tower (see above), are not open as a museum, yet they are fairly easily accessible to the general public. They are the most sizable remains of the planned installation for four 38 cm coastal guns, part of the ambitious coastal defense program of the Third Reich known as Atlantic Wall. This particular fortress became pointless after the break-out of hostilities between Hitler’s Germany and the USSR in 1941, since the line of the front shifted significantly towards the east, far away from Bornholm. Since construction works were correspondingly halted, only the unfinished emplacements of two of the cannons remain today, respectively Nr.3 and Nr.4.

The emplacement Nr.3 is easily accessible from the road. You can see the large round base prepared for the revolving gun. The central pinion is still there (note the big diameter of the metal screws, compared with the cover of my wide lens!).

The circular corridor for moving the shells and taking them to the gun can be easily walked.

The construction to the north was planned to shelter the troops manning the station, as well as with a technical part for storing the shells and the explosive cartridges. Many rooms can be accessed – albeit a torchlight is mandatory in this area. However, they are completely empty, and there is nothing more than bare concrete.

The second site, Nr.4, is more secluded within a group of private homes. However, it can be accessed fairly easily by walking. It is basically a twin of the other emplacement, and the state of conservation (including, unfortunately, tons of stupid graffiti) is the same.

Getting there and moving around

The two emplacements are geographically extremely close to the Cold War tower described above. It is possible to park at the tower, in the large parking areas closer to the white dunes strand, or along the road in proximity to these installations.

The coordinates for parking and getting a quick access are for Nr.3: 55.00058432993301, 15.080803777073971, and for Nr.4: 55.00255210231893, 15.084640862385443.

Both sites are not fenced and accessible 24/7. Visiting may take 15 minutes for each of the emplacements – the condition is unfortunately not ideal, with many graffiti likely such to spoil your pictures.

Soviet War Memorials Southeast of Berlin

The final battle for the conquer of Berlin was a massive operation carried out by the Soviet Red Army, who had come on the line of Oder river, marking today’s border between Germany and Poland, at the conclusion of the westward march on the territories of Eastern Europe previously taken over by the Third Reich.

Witnessing the dramatic lack of men and supplies on the German side, the final Soviet attack from that position was launched on April 16th, 1945, to end just less thank two weeks later with the death of Hitler, the conquer of Berlin, and soon after with the German capitulation in early May. In this short time, the Soviets penetrated and gained control of a significant part of what was to become the territory of East Germany, including the capital city of the Reich.

It is estimated that the troops amassed in the spring of 1945 for this operation exceeded 2.2 millions on the Soviet side, whereas the contingent available for the defense of the region on the German side was below 300 thousand men, including almost improvised corps of elders or extremely young people, lacking any military training and experience. As a matter of fact, the original German war machine had been drained of resources also due to the eastward advance of the Western Allies in Western Europe and Germany, where some millions German soldiers were taken prisoners. Actually, by April 1945 the line of the Western front had reached East to the towns of Leipzig, Dessau, Magdeburg and Wismar, very close to Berlin, and all later ceded to the Soviets according to the Jalta and Potsdam agreements.

The defense of Berlin from the Soviet attackers was strenuous though, and heavy losses were recorded on both sides.

One of the most visible remains of these war operations today is a a number of memorials and war cemeteries, of larger and smaller size, scattered over the territory around Berlin. The most conspicuous such memorials are those erected by the winning Soviet forces. Besides their primary role of remembrance, they were in most cases erected soon after the end of the war, then making for an interesting historical trace from that age, when Stalin was the undisputed ruler in the Soviet Union. Their style often reflects the mix of pomp and simplicity typical to the communist art from the time.

Memorials related to these events can be found in Berlin (see here and here) and around. Some to the north of the town have been described in this post. In the present one, three memorials related to the battle around Berlin and located east and south of the German capital are covered – Seelow, Lebus and Baruth.

Photographs were taken in 2021 and 2023.

Sights

Seelow

The memorial in Seelow was designed and installed in 1945, soon after the end of the war in Europe, and was therefore one of the first of the kind. The location is that of the Battle of the Seelower Heights.

The small town of Seelow is located about 8 miles west of the Oder river, marking a natural border with Poland. The hills around the town dominate the flat country reaching to the river. Therefore, for the defending Wehrmacht, this was a natural obstacle between the Soviet invaders and Berlin. The hills were fortified heavily with guns and mortars, and the villages in the area were evacuated in anticipation of a major confrontation.

Fighting was started on the fateful April 16th, 1945, when a Soviet attack was triggered all along the line of the Oder, with a major focal point in the region of Küstrin and Seelow.

The battle went on for four days despite the clear imbalance of resources in favor of the Soviets, due to the advantageous geographical position of the heights around Seelow and the effectiveness of the German defense.

The memorial was erected around a simple statue of a Soviet soldier, put on top of a pinnacle, and portrayed beside the turret of a tank.

To the base of the pinnacle is a small Soviet cemetery, with some marked graves and some gravestones with multiple names, or dedicated to unknown soldiers perished in the battle.

From the cemetery, a good view of the plains extending to the east, where this fierce battle was fought in April 1945, can be observed from a vantage point. Purpose-designed maps allow to retrace the positions of the attackers and to pinpoint relevant locations.

To the base of the monument is a memorial museum. The exhibition is compact but very interesting. Two thematic areas are presented, one related to the historical reconstruction of the battle, the other to the history of the monument and the archaeology of the battlefield around Seelow.

Among the artifacts on display related to the history of the battle are German and Soviet uniforms, machine guns and rifles.

Interestingly, also mortar shells carrying leaflets are on display: these were employed by the Soviets, who launched propaganda leaflets inviting Germans to surrender, and even passes for the German military who wished to defect to the Soviets side. An armband of the ‘Deutscher Volkssturm Wehrmacht’, the non-professional corps recruited by the Third Reich in a desperate move to gather fresh units for the final defense of the German territory from invasion during the last stages of the war, is also on display.

The history of the monument is interesting as well, and shows how it evolved from being primarily a Soviet monument – like others in the area – to a public gathering place for official ceremonies in the German Democratic Republic – a place for the celebration of friendship between the USSR and the GDR. Historical pictures, and the addition of a poetic commemoration stone written in German only to the base of the monument, witness this evolution.

Outside the museum, a courtyard is framed by two original small obelisks with inscriptions in Russian and Soviet iconography. On the courtyard, some heavy armored vehicles – including a Katyusha rocket launcher – are on display.

Getting there and visiting

The monument has a special relevance in the history of the liberation of Germany, and has been modernized and updated over the years. It is still a rather relevant destination for visitors. A ticket is required for the museum only. A visit to the monument may take 20-30 minutes. A complete visit including the museum may require 45 minutes to 1 hour.

Access is very easy, since the location is immediately to the side of the road leaving Seelow for Küstrin (now Kostrzyn, Poland). The name of the site in German is ‘Gedenkstätte Seelower Höhen’, and the address is Küstriner Straße 28a, 15306 Seelow. A small parking can be found right ahead of the access, further parking options cross the street and near the railway station, 1 minute away by walk. A new modern building to the side of the monument hosts the ticket office and a small shop. Website with full information here.

Lebus

The cemetery in Lebus, located on the German bank of the Oder river, about 10 miles southeast of Seelow (see above) was activated already in April 1945 for burying Soviet soldiers perished in the final war actions against Germany. Starting 1946, the status of Soviet cemeteries and monuments established on the territory of the Third Reich was officially defined. The Lebus site received Soviet staff perished in Germany after the war, or unrecognized fallen Soviet soldiers whose remains were found in the years soon after WWII on the East German territory.

Following an agreement between Russia and reunified Germany, extending the relationship formerly existing between the USSR and the GDR on the management of war memorials, the Lebus site became a Russian cemetery. It was refurbished in 2014-16, and at the time of writing it is still an active cemetery, often receiving the remains of Soviet soldiers moved from elsewhere, or still found in the area.

It is estimated that more than 5.000 from the USSR/Russia are buried in Lebus.

The memorial is not much visited by the general public, and is an authentic place of remembrance, sober and silent.

The architecture is rather simple, with a central perspective leading to an obelisk with a red star on top, a hammer and sickle emblem to the front, and inscriptions in Russian.

To the sides are two lateral wings, where the names of many fallen soldiers are inscribed on memorial stones.

To the sides of the perspective are an anti-tank cannon, and some more fields, marked with marble red stars as places of interment of unknown soldiers.

Also two further memorial walls with many names in Cyrillic alphabet are symmetrically placed to the sides of the perspective.

Getting there and visiting

The location of the Soviet cemetery in Lebus, now called officially ‘Russische Kriegsgräberstätte in Lebus’, is on Lindenstrasse, immediately after leaving Strasse d. Freiheit, Lebus. It is clearly marked by an indication sign, and recognizable by the external fence. Parking can be found 200 ft further north on Lindenstrasse, on the side of a local school.

The site is not mainly a touristic destination, but a real, well maintained (war) cemetery. It is apparently open 24/7 and not actively guarded. Visiting may take 20 minutes, or more for specifically interested subjects.

Baruth

The Soviet war cemetery of Baruth was erected between 1946 and 1947 for the fallen soldiers of the Battle of Halbe. The battle was a last confrontation between the Soviet Red Army and the Wehrmacht, taking between April 24th to the first days of May 1945 – the very last battle out of Berlin.

The battle was fought around the village of Halbe, south of Berlin, between what remained of the German defense retreating from the bank of the Oder, and two large columns of the invading Soviet Army. The German forces got mostly surrounded in a salient. Losses were very heavy on both sides, of the order of the tens of thousands.

The war cemetery for Soviet soldiers, the final resting place for some thousands of fallen troops, is clearly visible when passing by, thanks to the two T-34 tanks put as gate guardians.

The architecture of the place is rather simple, and composed of a rectangular yard crossed by an alley, leading to a very tall obelisk. The obelisk features a big metal star on top, and a hammer and sickle metal emblem in the middle.

To the base of the obelisk are two bas-reliefs with war scenes.

A number of marked gravestones can be found on the greens around the obelisk. More recent – yet pretty old – additions, somewhat altering the original neat appearance of the ensemble, include a wall with applied gravestones and names inscribed on it.

Getting there and visiting

The Baruth war cemetery, named ‘Sowjetischer Ehrenfriedhof Baruth/Mark’ in German, can be found along the road 96 (Bundestrasse 96), about 1 mile north of the homonym town of Baruth. The monument can be clearly spotted on the eastern side of the road. A small parking can be found ahead of the entrance.

Due to the secluded and isolated location, the place is not a highly popular tourist destination, yet it is frequented by relatives and descendants of those interred on site. It is well cared for and perfectly maintained. It is apparently open 24/7.

A prototypical Soviet war cemetery from Stalin’s years, likely the largest in the region south Berlin, it is definitely worth a stop when visiting the area. A visit may take 20 minutes.

Notably, the place is located about 7 miles south of Wünsdorf (see this post), the former Soviet headquarters in the German Democratic Republic, which is crossed by the same road 96.

Preserved Cold War Bunkers in Northern England

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

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

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

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

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

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

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

Hack Green Secret Nuclear Bunker

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

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

History

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

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

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

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

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

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

A tour of the bunker

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

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

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

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

Ground floor

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Underground floor

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Getting there and visiting

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

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

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

York Cold War Bunker

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Getting there and visiting

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

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

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

Traces of World War II in Norway – Highlights

War actions in Scandinavia constitute a crucial stage in the unfolding of WWII events in Europe. The strategic position of the Scandinavian peninsula was not overlooked by strategists in the Third Reich and the USSR, and by the Western Allies. As a matter of fact, the German invasion of Denmark and Norway took place as early as the Spring of 1940, starting just weeks before the invasion of Holland, Belgium and France.

History & Remains – A Quick Summary

For Germany in WWII, the long and impervious coast of Norway constituted an ideal strong point to carry out raids over the North Sea, Norwegian Sea, the northern Atlantic and the Barents Sea, interfering with resupply convoys from Britain and the US. Especially after the start of the war against the USSR in 1941, the polar routes going to Murmansk – the only non-freezing port on the northern coast of the USSR – were within range of German warships and aircraft operating from the north of Norway. Control over Norway and Denmark meant total control on the access to the Baltic Sea, thus protecting the northern coast of Germany from direct attack by the Western Allies, allowing unimpeded action against the Soviet Union on that sea. Of the greatest importance in the northern European territory was also the abundance of raw materials – mainly metals for industrial production – so desperately needed by the Third Reich.

For the Allies, keeping Scandinavia was an objective of great relevance in the early stages of the war, since this territory could be a convenient springboard to launch attacks against the flat and easy coast of Germany. In the rapidly changing complex alliances and diplomatic relationships of the early stage of WWII (1939-40), Norway and Sweden tried to keep out of the war. Finland fought the Winter War against the USSR (itself one of the results of the Ribbentrop-Molotov pact, albeit not to the knowledge of the Finns), loosing part of its territory and strengthening its link with Germany for some years to come (see this post). The Third Reich attacked Norway by air and sea in April 1940, and help was sought especially in Britain. King Haakon VII of Norway left for exile in England, and the initial battles of WWII between the Reich and the UK were fought – mainly at sea – in proximity of Norwegian ports.

The Atlantic Wall

Possibly the most impressive military trace of WWII in Europe, the Atlantic Wall – a defense line stretching from France to northern Norway – was designed and built in Denmark and Germany, immediately following the successful push of the Third Reich into these Countries. Actually, those are the Countries where the most relevant remains of this interesting trace of war can be found today. A very ambitious project both in purpose and required resources, the Atlantic Wall never reached completion. Despite that, the geography of Norway, with a coastline featuring only limited access to the inland area, allowed to create an effective barrier against a potential enemy landing. Hundreds of gun batteries, complemented with anti-aircraft artillery and radars, constituted a powerful deterrent against any invasion. As a matter of fact, after the unique episode of the Battle of Narvik in the early stages of WWII, no Allied forces ever landed in Norway from the sea for the rest of the war.

A complete visit to all sites of the Atlantic Wall in Norway is a really immense task, due to the number of installations and their geographical remoteness. However, a few impressive highlights can be found in convenient locations, and can be easily visited by everybody. In this post some of them are presented – the colossal battery ‘Vara’, the southern fortified area of Lista, the forts of Fjell and Tellevik near Bergen, and the massive cannons of Austratt.

War Museums

But other fragments of the rich legacy of WWII in Norway can be retraced also away from the preserved installations of the Atlantic Wall. An interesting page is that of naval warfare deployed by the Navy of the Third Reich – the Kriegsmarine – to counter Allied shipping activities. Names like Tirpitz, Scharnhorst and Gneisenau are frequently found in history books as well as in movies or scale model shops, and they are just a few of the mighty vessels linked to the Scandinavian war theater. Dedicated exhibitions can be found in little but impressively rich museums on these topics. In this post, the Tirpitz Museum in Alta, the War Museum of Narvik and the exhibition in the visitor center of North Cape are covered.

Special interest sites

Heroic actions involving the Norwegian resistance organization are proudly remembered all over the Nation. A particularly interesting location being the Rjukan hydroelectric power-plant, which produced heavy water, a key-component in the research leading to the preparation of fissile material. This strategic asset was highly needed by the German nuclear program. On the other hand, its possession by the Third Reich was seen as a clear and present danger by the Allies, who tried to have the plant destroyed in several instances. The Norwegian resistance was clearly much involved in sabotage missions, due to the difficulty in targeting the place through air bombing raids. The power-plant is today a nice museum, covered in this post.

Photographs in this chapter were collected on a visit in August 2022.

Sights

The map below shows the location of the sites mentioned in this chapter. Their listing in the descriptions roughly follows a clockwise sense, starting from the southernmost point of Kristiansand (Vara battery). Red items are in disrepair, whereas blue ones are official tourist destinations.

Vara Battery – Kristiansand

The Vara battery was built as the core of the strongly fortified area around Kristiansand. Thanks to its position close to the southernmost tip of the Norwegian territory, this port town is still today very busy with passenger and freight traffic from nearby Denmark.

The Third Reich military started to lay sea mines as soon as it gained control of both sides of the Skagerrak strait. The coast around Kristiansand was reinforced with several coastal artillery pieces, and production of a set of special 38 cm caliber guns – called Siegfried -was started by the Krupp ironworks in Essen in 1940. The aim was that of controlling access to the Baltic sea by means of two batteries of long-range naval guns, one to the south in Denmark (Hanstholm, see here), and one to the north in Kristiansand.

The cannons should be capable of revolving by 360 degrees, and special concrete rotundas were prepared for the scope in a location called Møvik, on the southwestern end of the gulf of Kristiansand. The complex morphology of the terrain in this site led to a smaller than desirable area for the battery, where all technical buildings – including ammo storages – had to be built relatively close to one another. These massive constructions alone, built by the same ‘Organisation Todt’ responsible for the implementation of the coastal defense positions all over Europe, make for a remarkable work of engineering, carried out with the help of local builders, working relentlessly around the clock to have these emplacements ready as soon as possible.

In the event, only three of the four Siegfried cannons made their way to the battery in Kristiansand, one being apparently lost when the transport ship carrying it was sunk on the Baltic Sea. Transporting these 110 ton, around 60 ft long barrels by rail from Germany into the narrow valleys of Scandinavia was not an easy task. However, two cannons were test-fired in May 1942, and the third in November the same year.

The battery received the name ‘Vara’, after a high-ranking official killed in Guernsey in 1941.

Battery Vara went through the war without seeing an involvement in any major war action, and was mainly test-fired only. The whole installation, comprising target detection points, analog computers for target aiming, ammo storages – including more than 1.400 shells! – and many other service buildings, was inherited intact by the Norwegian Armed Forces in 1945, similar to many other installations along the coast of the Skagerrak and the North Sea. It was incorporated in the Norwegian coastal artillery between 1946 and 1954, being later placed in reserve having by then become obsolete for Cold War warfare standards. Two cannons were scrapped, whereas one – the only entirely surviving battery Nr. 2 – was luckily kept. The site survived subsequent stages of demolition works over the next decades, but in the early 1990s it was finally re-opened as a museum.

Cannon Nr. 2

Today, the centerpiece of the visit is constituted by a walk around the perfectly preserved building of cannon Nr.2. This bunkerized building is composed of a set of technical rooms, for ammo assembly and storage, as well as for services like Diesel power generators, and an adjoining rotunda, where the big cannon revolved around a pinion, and could be pointed to its target, following instructions from the battery control center. The latter elaborated target data from detection, identification, measuring and range-finding positions scattered around the battery perimeter.

Access to the back of the concrete building is via the original hatch, closed by iron doors. You can see the narrow-gauge railway track leading in. This linked the cannon buildings with the ammo storages around, and allowed to supply the cannon with ammo parts (the explosive cartridge and the shell are not assembled in a single unity for larger cannons, unlike for lighter weapons). The hatch drives you into a long corridor, the backbone of the bunkerized quarters behind the cannon rotunda. Here some shells have been put on the original railway trolley for display.

The cannon building hosted a permanent watch of a few men, which manned it permanently in shifts. A living room with some berths is the only one offering some comfort in the building.

A number of rooms in the bunker are dedicated to the power generator plant. A primary and a back-up generator share the same room. Of special interest are the labels on all machines and mechanisms, proudly made in Germany – in some cases, by brands still existing today.

Electric power was required for the motion of the cannon, besides for smaller appliances like lights and radios. The cannons could make use of the regional grid, but since an unstable supply might have damaged the cannon motors, aiming operations were often carried out on the controlled internal power grid, fed by the generators, and producing an optimal output.

Beside the generator room, the air conditioning plant (not for comfort, but to slightly pressurize the bunker in order to repel and pump-out poisonous or exhaust gas), the Diesel tank and the water tank for cooling the generator can be seen in adjoining rooms.

To the far end of the corridor, a radio room was used to maintain a link with the battery command post, located more than 1 mile away from Vara battery. Actually, by design the electric signals to orient the cannon could be given by the control post, and the radio communication system was there for backup.

On the other side of the corridor with respect to the generator rooms – i.e. towards the cannon rotunda – are four adjoining rooms, used to store the components of the explosive cartridges and shells. The shells and cartridges prepared for firing were moved via a crane to a tray, and from there sent side-wards to the rotunda, where they were loaded on a trolley. The cranes, trays and slots linking these rooms to the rotunda can be found around the area of the bunker closer to the rotunda.

The cranes moved along tracks hanging from the ceiling. These tracks had some switch points, allowing to allow the crane to move across different rooms in the bunker.

Inside these rooms, today you can find much original material of special interest. Specimens of high-explosive (yellow) and armor-piercing (blue) shells are displayed. The weight of the shells was around 800 kg, where the cartridge could feature different weights, roughly from 100 to 200 kg.

The top range of these cannons and shells was around 43 km. Smaller 500 kg shells could alternatively be fired by Siegfried cannons, with a longer range of 55 km. Furthermore, the cannon could be test-fired during drills with smaller caliber shots, by reducing the bore of the cannon. This was a very useful feature, since the estimated loss of barrel metal due to attrition was a staggering 0.25 kg per shot, implying a life of the barrel of only around 250-300 shots, firing with sufficient accuracy. Shooting smaller shells allowed to spare barrel wear and extend the time between overhauls of the cannon.

The sealed canisters for the explosive cartridges, with original markings in German, can still be seen piled in a room!

More material on display includes a rare example of fire direction computer. Actually, that on display is smaller than the one originally used for the long-range cannons of Vara battery, but it provides a good idea of the level of sophistication of this mechanism. Data like target distance, velocity, orientation, wind speed and direction, etc. were set as input to this analog computer, producing fire direction variables to point the cannon. An incredible masterpiece of engineering and craftsmanship, this type of computer is difficult to find in museums, and allows to appreciate the level of development of warfare back in the 1940s.

Data including range of the target was found with the help of special instrumentation. A stereoscopic range-finder was installed in the battery command post, with an arm of 12 m, which allowed good accuracy for very distant targets – required for the long range of the cannons of Vara battery. Smaller instruments with the same principle are displayed in one of the rooms.

Among the special features of this bunkerized building are the restored, original writings from German times, as well as a one-of-a-kind painting made by a Soviet prisoner of war.

From the bunkerized room, you can get access to the rotunda. Cartridges put on trolleys moved along a circular railway track all around the rotunda. This way, cartridges could be taken to the cannon whatever the direction it was pointing. Once to the base of the cannon turret, the explosive charge and the shell were lifted separately by means of two special elevators, up to the level of the gun shutter.

An impressive feature of the rotunda is the ring cover for the circular railway. In order to protect the railway passage from above, while allowing the cannon to rotate, a roof made of thick metal scales was implemented. When revolving around the pinion, the cannon turret would automatically lift the scales on its passage. The sound of the scales being lifted and released while the cannon body was revolving must have been really an experience!

Pictures can hardly tell how big the cannon turret is!

Following an exploration from beneath, you can exit the bunker building, climb up to the level of the barrel, and finally enter the turret.

Here the back of the barrel dominates the relatively large firing chamber. The shutter has been left open, so you can see the sunlight through the barrel.

The shell and explosive charge were received from the two elevators on a special tray, and here they were finally aligned one before the other. Somewhat in contrast to the top-notch technology level of the installation, the cartridge had to be pushed from the back into the barrel by hand. A long wooden stick was used for the task. Actually, it was so long that it protruded from the back of the cannon turret, thus requiring a small hatch to be pierced in the metal armor correspondingly. On one side of the barrel, instrumentation for measuring the pointing direction is still in place.

Air-pumping mechanisms can be clearly seen, similarly to communication phones to the back and top of the room.

Cannon Nr. 1

The position of cannon Nr.1 was prepared unusually close to that of Nr.2. As said, this was due to the limited available area on the uneven coast section where the battery was put in place. However, Nr.1 never received a cannon. Conversely, it was modified later in the war, when experimenting with cannon protection from air-dropped high-yield bombs. The rotunda was capped with a very thick concrete roof, sustained by sidewalls which limited the side-wards rotation of the cannon to 120 degrees.

The rotunda can be walked freely. The central pinion is still in place. Inside, the ceiling is covered in original metal panels. The round corridor for the trolleys can still be seen, but there is no access left to the bunkerized part.

The firing position can be climbed, and from the elevated top you get a great view of the battery and of the area ahead of it.

Other buildings

Following the railway around the site is a great way to find what remains today of the original installation. There are two bulky ammo storages. These were reportedly more thickly armored than usual, in view of a higher risk of getting hit, due to the unusual proximity with the cannons – designated targets for the enemy.

Furthermore, other smaller buildings are scattered around, which may have served as storage for lighter weapons.

The positions of cannons Nr. 3 and Nr. 4 have been largely demolished, and access is permanently shut to the bunkerized part. However, you can easily climb to the top level, to get a nice view of the rotunda.

Visiting

Vara is in the top-five list of the most famous surviving installations of the Atlantic Wall in Europe, and a visit to this destination is in itself a good reason for a detour to Norway for war historians and like-minded people. Due to its proximity to the port of Kristiansand, just minutes apart by car, and the relatively easy-to-reach location in the most populated part of Norway, it is also a top destination for any tourist in the area. As a matter of fact, the place is run as a top-level museum, with great reception capability, and is visited by thousands of visitors per year.

Visiting can be performed on a self-guided basis, with an explanation leaflet which allows to get much from your visit, especially if you are not new to installations of the Atlantic Wall (which are mostly standardized, despite Vara having really oversized guns!). A tour of the main features – cannon Nr.2 and the building of Nr.1 – may take 1 hour at least, for an averagely interested person. For an in-depth visit and a quick tour of the premises including other remains, more than 2 hours are needed. Thanks to the exceptional level of conservation and the explanation of whatever is on display, the visit is not boring and may be very rewarding even for younger people.

Large parking on site, picnic tables and warm reception are available – as usual in Norway! Website with full information here.

Nordberg & Marka Batteries – Farsund

Located in the southwestern corner of the Norwegian territory, about 100 miles south of the port of Stavanger, the municipality of Farsund encompasses a number of small coastal villages, around the landmark represented by the lighthouse of Lista.

Two batteries were set up by the German occupation forces as part of the Atlantic wall, both fully operative by 1942. The northern one is called Nordberg fort, where the southern one, very close to the shore line, is known as Marka fort. Between the two, the Germans installed a full-scale airbase, with a runway of roughly 1.5 km, complemented by hangars and shelters largely standing today. Following the end of WWII and the withdrawal of the German military, all these installations were converted for military use by the Norwegian armed forces, which also developed the original airfield into a more modern airbase by stretching the runway.

Today, Nordberg fort is a museum. The German Navy was in charge of the station, which had as centerpieces three 150 mm cannons, with a range of around 23 km. The cannons have been scrapped (with the exception of a lighter piece of Russian make). However, the firing positions are still there, linked by a semi-interred trench.

You can see also the original control point for the battery, developed by the Norwegians more recently, and the concrete base for a radar antenna originally on site.

Several original buildings for services – canteen, hospital,… – are still there, making for a an interesting opportunity to see how this installation looked like back in the 1940s.

The Marka fort was assembled around six 150 mm guns, located very close to the sea, grouped in two batteries of three firing positions each. A huge bunkerized command post was built in the premises of the fort. Today, after the Norwegian military left at the end of the Cold War, the Marka battery is basically a ghost site, despite being still in a relatively good shape.

The control bunker is especially interesting, since you can access the top level and watch the sea from the very same room and windows originally used by the German Navy troops! The general arrangement of the bunker is similar to other command posts you can find on the Atlantic Wall – especially in Denmark (see here).

The positions for the coastal guns can be reached close to the control bunker. They are uncovered round areas, slightly below the level of the ground, framed by a circular reinforced sidewall.

More Atlantic Wall remains, like bunkers, foundations for radar stations, or emplacements for lighter guns, can be  be found scattered in the area of Farsund – which kept its military site status well after the Germans had left.

Visiting

The museum of Nordberg keeps some of the buildings on the respective site open. However, the majority of the site is open 24 hours, and can be walked freely. A visit may take about 1 hour. A convenient parking can be found right ahead of the modern and welcoming visitor center, from where you can effortlessly reach most of the points of interest in this installation. Website with full information here.

The site of Marka – not part of any museum – can be approached at any time with some walking in the rural area along the coast line. A good starting point for an exploration is here, where you can leave your car and move along an easy trail to the command bunker and the gun rotundas about 0.5 miles west.

Fjell Fortress – Bergen

Bergen was a strategic base of the German Navy, which received a fortified submarine deck among the largest, most active and longest lasting in the history of WWII. The complex morphology of the territory around this port town allowed to effectively protect the access by means of a network of nine firing emplacements. One of them – Fjell – was of exceptional power and range.

It was built between 1942-43 diverting one of the batteries of battleship Gneisenau, which had been damaged beyond repair by an air raid while in port at Kiel (Germany). The battery was composed of three 28 cm guns in a single turret. The latter was very compact in design, a real masterpiece of naval engineering, but nonetheless it featured a rather tall substructure, with all that was needed to operate the guns – protruding from the relatively sleek top of the turret, surfacing on the ground.

Placing this special battery in Fjell required carving the rocky coast, creating a cylindrical underground pit, inside coated with concrete, to host the turret. The turret, an assembly of around 1.000 tonnes with the guns on top, was then transported up to this elevated site, and lowered into the pit. The battery was test fired in the mid of 1943. It acted as an effective deterrent, and reportedly never used in combat.

The battery was incorporated in the Norwegian coastal defense after WWII, and sadly scrapped in 1968, since by then obsolete, but not yet considered an historical landmark.

Clearly, the battery was in the middle of an off-limits military area in wartime, where bunkers for several services and for the the troops, at least two radar antennas and many emplacements for lighter defensive weapons were installed to protect the battery from ground and air attacks.

Today, the bunker-pit where the turret used to rest is the centerpiece of a visit to the site. Starting from the visitor center on top, where the guns used to be, you can descend to the base of the cylindrical pit – roughly 30 ft in diameter and 75 in depth! Here you can see the rooms originally employed for storing the explosive cartridges and the shells for the cannons. These were supplied on trolleys and slides, and sent inside the metal turret, to be lifted up to the level of the cannons for firing.

Most of the original German mechanical and electrical systems is still there to see, including wiring, phones, cranes, trolleys, and examples of shells and cartridges.

Back then, you got access to these storage areas from an entrance on the same level (i.e. not from the top of the turret, but from the base). You can see this entrance, as well as the curved corridor leading from the gate to the ammo storage area. Here, examples of sea mines and other war material can be found. The corridor has narrow-gauge railway track, which was used for resupplying the ammo storage from outside.

The corridor is curved, and firing positions are strategically placed to cover it, in order to counter enemy intrusion.

The bunker gives access to the living quarters for the troops. These are well preserved, and feature brick walls to help insulating the inside from the wet rock of the walls and ceilings.

Services, like toilets, sauna, washing machines and more, are original from the German tenancy. Especially the water basins appear very stylish, a good example of German design from the era.

Besides the main turret bunker, as said the Fjell site offers other constructions on a vast area, which can be checked out from the outside – also since the premises are at least formally military grounds still today.

The road reaching the site from the parking, gently climbing uphill, is reportedly the original main access to the Third Reich site. An interesting tank-stopping device can be seen to the lower end of the road – heavy stones on top of light pillars on the sides of the road. The pillars could be blown, and the stones would fall cutting the road, in case of a potential intrusion.

Visiting

The fort of Fjell, about 15 miles west of central Bergen, is professionally run as a museum. Parking is only possible to the base of the cliff where the turret used to stand. From there, a 0.8 miles road climbs to the entrance. The scenic location and the nice rural area around make for an enjoyable walk. Visiting inside is only possibly on guided tours, offered also in English (an possibly other languages). A small restaurant can be found on top, where an observation deck has been built in place of the battery.

The location of the parking is here. A visit may take around 45 minutes, excluding the time needed to climb uphill and descend to the parking. Website with full information here.

Tellevik Fort – Bergen

The coastal fort of Tellevik, on the eastern head of the Norhordland Bridge, 15 miles north of Bergen, was part of the lighter defense artillery put in place by the German military to defend any access by water to Bergen. The battery was built by order of the Third Reich, profiting from the forced labor of Soviet prisoners of war.

Lighter howitzers were enough to cover the narrow water passages in proximity of the town. The elevation of the emplacement is low, slightly above the water surface.

The battery of Tellevik was centered on two such howitzers, placed on open-top positions. The two guns can be seen still today, on round concrete firing positions. The giant bridge today largely obstructing the field of sight was not there at the time of the German occupation.

The site displays also a concrete trench, connecting the firing positions with a command post for the battery.

A monument to Norwegian seamen victims to sea mines laid by the German to protect the access to Bergen is concurrently located on the site of the Tellevik battery.

Visiting

Tellevik is an open air memorial, which can be walked freely 24/7. It can be reached by inputting these coordinates to a GPS navigation app.

A visit may take about 15 minutes, a nice detour from exceptionally crowded downtown Bergen.

Austrått Fortress – Austrått

Similar to Bergen, the major port of Trondheim was a strategic base for the German Navy. Protected by a long firth, the port was an ideal base for submarines and warships, to intercept convoys in the North Sea, Norwegian Sea, the Atlantic Ocean and the Barents Sea. Correspondingly, a number of coastal forts was prepared by the German occupation forces to counter any unauthorized access to the waterways leading to Trondheim.

The most powerful and impressive of these batteries is the Austratt Fort. Similar to the fortress of Fjell near Bergen (see above), Austratt received one of the turrets of the ill-fated battleship Gneisenau, damaged while moored in Kiel, in February 1942. A control and aiming position was put in place a few miles apart along the coast, whereas the battery was surrounded by an off-limits area, stuffed with bunkers for the troops, ammo storage bunkers, and lighter guns for protection against an attack by land.

A major difference between the two ‘sister sites’ of Fjell and Austratt is that in the latter the cannons are still there!

Following the installation of the turret, test fired in September 1943, the fort saw little action, acting as a deterrent, and effectively preventing any serious intrusion by the Allies towards Trondheim from the sea. After the demise of the Third Reich, the fort was taken over by the Norwegian coastal defense, stricken off in 1968, and restored as a museum in the early 1990s.

The cannons are on top of a hill. From the outside, the massive three-barreled turret is really impressive in size!

The barrels can be seen besides the original range-finder – with its impressive arm, granting good measuring accuracy even at a large distance from the target. This item, with its bell-shaped cover, was originally part of the control point, located southwest of the battery, in a location currently very close to an active base of the Norwegian Air Force (Orland).

Despite access to the the firing chamber being possible through a hatch to the back of the turret, the tour follows the way a shell would travel from storage to firing. Hence you start your tour from an entrance to the side of the hill, at the same level of the bottom of the cylindrical tower supporting the guns. This metal tower was taken from the Gneisenau together with the cannons, and put in a pit carved in the rock for the purpose in Austratt.

Access through the side of the hill is protected by a smaller gun. Once inside, you find yourself in a curvy corridor, with a narrow-gauge railway track for the trolleys needed to carry the shells and cartridges inside. A firing position behind an embrassure points against the entrance, for further protection of the site against an intrusion.

The bunker in Austratt – but the same happened to many installations of the Atlantic Wall in Norway – was plagued with severe humidity problems. Immediately besides the entrance, a room with a water basin is fed by natural water dripping from the ceiling and from the rocky walls around.

Original machines for tooling, put in place for maintenance purposes back in the Third Reich years, are still there and working. Similarly, a primary and a backup Diesel generators supplying the fort are still in place, with all ancillary plants, like big Diesel and water tanks for cooling. This is original machinery too, as witnessed by the tags of the mechanical components, all made in Germany.

Living quarters were at the bottom level too. Trying to supply some comfort, the rocky walls were covered with bricks and wood, especially against humidity. These rooms have been partly refurbished with a good resemblance to the original ones. They include the kitchen and some of the sleeping quarters for the troops. However, since humidity was really extreme, troops spent limited time here especially for sleeping, and provisional barracks were built outside of the installation instead.

Hygienic services were reportedly extremely advanced compared to Norwegian standards of the time. Fully working toilets, lavatories and showers were taken as a blueprint by the Norwegian Army after the war. The electric water heater put in place in the Austratt battery was apparently among the first installed in the whole Country – it can still be seen.

Explosive cartridges, fuses and shells arriving from the bunker entry you have walked through at the beginning of your tour would be eventually lifted upstairs. Shells, either high-yield explosive or armor-piercing, would be stored in a chamber featuring cranes hanging from the ceiling, used to put the shells on trolleys. These trolleys transported the shells to the lower level of the turret. The chamber where the shells were stored is physically separated by the turret by means of a concrete wall.

Tight compartments are often found in war bunkers of the Atlantic Wall, and this can be explained by the fact that the deadliest effect of an enemy shot (either a cannon shell from a warship, or an air-dropped bomb) would be that of an overpressure wave (shockwave), capable of killing many in just moments. Overpressure effects can be effectively reduced by putting physical obstacles on the way the shockwave would travel – walls, tight doors, etc. – or by forcing it into smaller passages, like hatches or smaller doors and windows. Therefore, bunkers like Austratt are built in rather small rooms, connected only through narrow hatches and doors.

Again in the storage chamber for the shells, extensive writing in German can be found on many of the mechanisms and electric plants. Everything is original and exceptionally well conserved, just like the Germans had just left!

The lowest level of the turret, where the shells would arrive from the storage chamber to be loaded on elevators going to the upper levels, is a masterpiece of engineering. The technical problem here was that of connecting the slides from the storage chamber, which are anchored to the ground, to the receiving slides on the turret, which could pivot around 360 degrees. The designer of the turret solved the issue by placing an intermediate ring, revolving independently, and capable of connecting the fixed slides from the storage chamber to the revolving platform on the turret. The extremely compact size of the overall design, originally prepared for fitting into a warship, and the elegance and precision of the mechanism resemble those of a pocket watch from the 1920s more than a cannon!

On the turret, you can see three elevators for the three barrels, which were therefore fed independently.

Going upstairs, you meet the storage room for the explosive cartridges. These used to be stored in sealed canisters on display, original from the time. This storage room is placed to the side of the corresponding level in the turret, in a similar fashion to the shells storage below.

Climbing up one more level inside the turret, you reach a platform with the motors for moving the battery around its vertical axis, and for lifting or lowering the three monster barrels. The motion involved high-pressure mechanisms, rather complex and requiring many valves and extensive piping.

To the back of each of the barrels, you can see a large empty volume for recoil. The battery rested on a ball bearing – one of the pretty sizable metal balls is on display.

Finally, the firing chamber can be found on the top level in the turret. Here the shells and cartridges were received, aligned and loaded from the back into the barrels by a pushing mechanical arm. Three independent mechanisms were put in place for the scope in the firing chamber.

To the front of the battery, instrumentation for aiming can be found, with writing in German. Also radio positions are there.

Battery fire could be triggered by a single man, sitting to the back of the turret in front of a control panel with three independent triggers.

You can exit the turret from the hatch to the back of the turret, concluding your tour. In the video below you can see a portrait of the battery from the air, made with a drone.

All in all, similar to the Vara battery (see above), Austratt is in an exceptional state of conservation in the Norwegian and European panorama of artillery engineering from WWII, and a visit may be super-interesting for any public.

Visiting

Despite being relatively close to Trondheim on a map, as usual in Norway, Austratt is a more than two hours drive from the town, and reaching requires taking at least one ferry. However, as noted, this location is a pinnacle in the Atlantic Wall, and surely deserves a visit for technicians and non-technical public as well, and of course for the kids.

Access to the exterior is possible at any time, but visiting inside is only possible on guided tours. The guide is very knowledgeable and makes the visit interesting also for a technically-minded public. The visit inside may take around 1 hour, more if you make questions and show some interest. Convenient parking by the gate of the fort, easy access to the area around the battery. Moving inside can be requiring for non-fit people.

Arctic Circle & North Cape

As pointed out in the introduction to this chapter, Norway is rich of memorials from WWII. Even close to some of the attractions in this wonderful Country which are must-see stops for other reasons, features recalling memories from war actions are offered to a curious eye.

Two notable examples are the visitor center of the Arctic Circle along the E6, as well as that of North Cape.

Scandinavia has been a bloody and extremely active theater of war all along WWII, and Norway was directly involved in significant war actions since the first year of the conflict. As a matter of fact, most of the impressive line of fortifications constituting the Atlantic Wall was erected by deploying forced laborers, typically prisoners of war from the Eastern Front, primarily including Russians, other people from the USSR, and Balkan prisoners.

Soviet troops attacked the northernmost German-occupied region from the North, together with the Finns, after the latter negotiated a separate peace with the USSR in late 1944. The retreating Germans opposed a fierce resistance, and it was in this latest stage of the war that most physical damage to towns and installations was caused in Norway, since German troops were ordered to burn up all positions they had to leave.

These facts explain the many Soviet monuments and war cemeteries scattered especially in the northern part of Norway still today – commemorating Soviet soldiers fallen either in war actions or as prisoners of war in the harsh conditions of northern Norway.

One such monument, albeit overlooked, is prominently placed besides the visitor center of the Arctic Circle.

The interest of Germany for Norway was primarily for its strategic position, which became an asset of special value after the start of the war against the USSR in mid-1941. The convoys feeding vital material to the USSR from Britain and the US had to go to Murmansk (see here) and the Kola Peninsula, i.e. over the Barents Sea. This was conveniently controlled by the German occupants, operating from the Norwegian coast.

In the visitor center of North Cape some panels are dedicated to this topic, showing an impression of the structure and routes followed by Allied convoys going to the USSR.

Detailed panels with maps and pictures recall the last battle of the German battleship Scharnhorst, which was confronted by the group of the British battleship HMS Duke of York, in an epic battle relatively close to North Cape. The massive German battleship, deployed to Norway with Tirpitz (a sister ship of the famous Bismarck) to block the resupply traffic to the USSR, was hit several times and finally sunk in the freezing last days of 1943. The battle was posthumously named ‘Battle of North Cape’. A detailed scaled model of the German battleship is similarly on display in the visitor center.

Visiting

The visitor center of the Arctic Circle on the road E6, with a small Soviet monument, can be found here. The monument is open 24/7.

The visitor center of North Cape is… at North Cape! The inside can be accessed during opening times, and the tables with information on WWII convoys and battles are on an underground mezzanine. Website with full information here.

War Museum – Narvik

The port town of Narvik was founded in the 19th century as a commercial base for exporting iron ore from Sweden. A small town by the sea, surrounded by steep-climbing mountains, and in a remote location well north of the Arctic Circle, Narvik was turned for about two months into a though theater of war for the Germans, following their occupation of Norway.

It was here that the British started a battle to stop the German push to the north, as soon as the 10th of April 1940, basically at the same time as the Germans had reached the town during their conquering campaign.

What resulted was a complex, multi-stage operation, lasting until early June 1940.

At first, the British fleet mounted a naval attack, carried out with a flotilla of five destroyers. This force clashed with the local German complement of ten destroyers. The British operation met with mixed success, and was finally repelled by the German navy operating in the narrow waters around Narvik, at the price of two destroyers on each side – plus several cargo ships destroyed in the battle. Three days later, on the 13th of April, a new force, composed of the British battleship HMS Warspite and 9 destroyers, launched another assault, resulting in the complete loss of the German destroyers fleet in the region – German warships were either sunk or scuttled.

The Germans however kept control of the town. A mixed force of British, Polish and French troops, together with the Norwegians, started an operation to conquer the town by land. The operation was successful, and the German troops had to retreat along the coast, away from Narvik. However, the start of the Battle of France – the invasion of France by the Third Reich – on the 10th of May, 1940, resulted in a rapid loss of priority of Narvik as a strategic target for the Allies. It was decided in Britain to withdraw from Norway, and to evacuate all previously landed military forces from Narvik. The town fell under German control on June 8th, basically concluding the conquer of Norway by the Third Reich.

The Allied landings around Narvik in 1940 where the first on the European continent in WWII, carried out without the participation of the US, more than three years before operations in southern Italy or Normandy.

The town of Narvik is still today an active commercial port of primary relevance in the region. The heritage of war actions is preserved in a purpose-installed museum, modernly designed and easy to visit.

On a first floor, the naval operations around Narvik are described by means of technological 3D board with virtual projections – very nice and lively. Around the board, memorabilia from the British and German warships taking part to the operations back in the Spring of 1940 have been put on display.

They include an original Nazi eagle from one of the ships. Since the campaign around Narvik included also air and land operations, war traces including parts of aircraft, guns, mortars, machine guns, first-aid kits and many uniforms are also on display.

Uniforms are from the many corps which took part to those actions – they are British, German, Polish and even French.

On a second floor, you are offered displays of artifacts retracing other aspects of WWII in Norway. These include land mines – put in place by the Germans along the coast, similar to Denmark, to impede Allied landings – an Enigma coding machine, Third Reich memorabilia, a section of the Tirpitz armored hull, radio machinery supplied to the resistance, as well as personal items belonging to former prisoners of war.

Finally, on the last floor heavier weapons are put on display, including torpedoes, light armored vehicles and more, even for post-WWII times.

Visiting

The battle of Narvik is one of the best known from WWII in Norway, and the little museum in the town center duly retraces its timeline, through an elegant exhibition, sufficiently rich to satisfy even the most exigent experts, but not so extensive to be boring for the general public. A really well designed museum, surely worth a visit, which may last from 30 minutes to 1 hour depending on your level of interest.

The location is right besides the town hall, and can be found here. Parking opportunities on the street nearby. Website with information here.

Tirpitz Museum – Alta

The German battleship Tirpitz was laid down as the only sister ship to the well-known Bismark. Eventually, she underwent developments which made her the heaviest battleship built in Europe. Her actions were concentrated along a limited time frame, between January 1942 and November 1944, when she was finally sunk by British Lancaster bombers, making use of Tallboy high-yield bombs.

She spent her operative life along the coasts of Norway, where she constituted an effective deterrent against a sea-launched Allied invasion, and was employed tactically against resupply convoys going to the USSR.

Tirpitz was a strategic target for the Allies, which tried to get rid of her by no less than seven war operations, meeting with limited success until the last one.

With an armor more than 30 cm thick, Tirpitz was marginally maneuverable especially at lower speed, but the hull was very difficult to penetrate, and the four turrets and eight 38 cm barrels, plus twelve side-shooting 15 cm barrels, complemented by many more defensive weapons, made it a dangerous asset against land and sea targets.

The ship capsized and sunk in shallow water in the bay of Tromso, and following the end of the war, she was largely dismantled. Original pieces of the ship could be collected, as well as some personal belongings from the crew. Some more were taken out from the water over the years.

The museum in Alta is dedicated to the memory of the ship, and offers an extremely rich collection of items connected with Tirpitz. Furthermore, by means of memorabilia items, it retraces the history of the war years in the northernmost region of Norway – Finnmark. The reason for installing the Tirpitz Museum in Kåfjord, near Alta, is bound to the fact that the battleship was based here for a period, as witnessed by some historical pictures. The museum has a rich guestbook, which includes top-ranking military staff from several Countries.

The small museum is home to some of the finest and largest scales models portraying Tirpitz. The level of detail and the accuracy of the reconstruction is really stunning.

Some smaller diorama models portray scenes from the life onboard, or details of special interest. An unusual one portrays the capsized hull of the ship, following the sinking!

Besides the scale models, original instrumentation, shells, wooden slabs from the deck, and more parts of the ship are put on display.

A room is dedicated to the operations carried out against the battleship. The ship was reportedly attacked several times without substantial damage. One of the attacks was carried out by the British, recurring to mini-submarines. Among the artifacts on display are the decorations to the men involved in these operations.

Extremely interesting artifacts in the museum include material from the crew, taken away after the sinking over the years – sometimes found in the area as recently as the year 2000.

These include typewriters, cutlery with swastika emblems, musical instruments, sport suits with prominent Third Reich insignia, and many personal belongings.

In one case, the cabinet or wallet of a crewman revealed cash and stamps from the time.

Among the countless items in this exhibition are original material – including radio stations – employed by the resistance movements in Norway, as well as light weapons, uniforms and decorations of the Soviet troops who operated in the Finnmark region, helping in repelling the Germans in the last stages of WWII.

On the outside, the anchor and parts of the armor of Tirpitz can be seen, together with an official memorial stone.

Visiting

The museum is located some five miles from Alta, in the small settlement of Kåfjord. It is hosted in a single, small wooden building – possibly a former canteen – to be found here, with a small parking nearby. A website with full visiting information is here.

Visiting the museum may take from 30 minutes to 1 hour depending on your level of interest.

Vemork Hydroelectric Power Plant & Heavy Water Facility – Rjukan

The nuclear program of the Third Reich is still today a matter for researchers, since – mysteriously enough – most documentation disappeared by the end of the war. Among the ascertained facts were the excellence of nuclear scientist in Germany at the time on the one hand, and the total lack of adequate quantities of raw material, or plants for processing it, to actually build real nuclear weapons on the other.

The latter is witnessed by the great strategic value attributed to the plant in Rjukan, hidden in a scenic deep valley in the region of Telemark, in southern Norway, about three hours by car from Oslo. A hydroelectric plant there – the exact name is Vemork power-plant – was employed to produce heavy water through a dedicated electrolysis separation process, which requires huge amounts of energy. Heavy water is a key component for the production of Plutonium – in turn required for atomic weapons – in heavy-water reactors.

Also the Norwegians understood the value of the plant. As soon as the winds of war started blowing from Germany in early 1940, heavy water then in storage was taken away to France, and later to Britain following the invasion of France by the Third Reich.

After Norway had been occupied by the Reich, the plant was at the center of three sabotage operations. Extremely risky and partly ending in disaster, these operations were carried out both by Norwegian and British staff, parachuted from Britain.

It took until 1944 to mortally hit the plant, well protected by its own natural setting. Two dedicated bombing raids carried out by US bombers damaged the plant beyond repair – at least in the late war scenario, when the Third Reich reaction capacity was weakening every day. The final act in the Norwegian heavy water saga was the sinking of the small boat – named Hydro – loaded with the reserve of heavy water from Vemork, having just started its trip to Germany on Lake Tinn.

The plant was again in business in the years after the war, and remained operative until the early 1990s, involved in production of various chemicals.

Today, it is a much visited museum. Actually, the most impressive part of the plant is that of the hydroelectric turbines. Aligned in a single immense hangar, these now silent giant machinery send glimpses of the original, fashionable early-1900 industrial style.

Some of the turbines and generator assemblies – manufactured by AEG, as witnessed by the labels – are really huge.

A suspended platform allows to capture with a bird’s eye the entire hall. Here you can see also completely analog control panels, again in a very elegant style from the era.

Visiting

The museum in Vemork can be reached in less than 3 hours driving from central Oslo. The power-plant can be approached walking from the parking (here) over a suspended bridge crossing the deep valley. The area is very scenic. The highlight of the show is the hall with the power turbines. A visit may take from a few minutes to more than 1 hour for more interested subjects.

Soviet ‘Monolith’ Nuclear Bunkers in Poland – Survivors & Ghosts

Since the beginning caught in the storm of WWII, Poland saw its border changed again in 1945 by the Western Allies and the USSR – the lack of natural borders meant that fate for this Country several times over the centuries. Furthermore, as a massive flow of Soviet forces had been pivotal in repelling Hitler’s forces, similar to other nations sharing a border with the USSR, Poland found itself deep in the sphere of influence of Stalin’s Soviet Union. A communist dictatorship was installed starting 1945, due to last until the end of communism in Europe in 1989.

As a matter of fact, Poland turned out to be by far the most populated and largest of Eastern Bloc countries. Strategically placed in the middle between the USSR and free Western Europe, with a wide section of the Baltic shoreline and a huge, mostly flat territory, similar to the German Democratic Republic nearby, Poland was the theater of a significant militarization effort by the Soviets. Not only the Polish army received Soviet war material in large stocks over the full span of the Cold War, but the Red Army also actually had significant assets scattered over Polish territory – its huge Northern Group of Forces being stationed there, with tanks, aircraft, dedicated bases, firing ranges, as well as several tens of thousand troops and their families, making for a kind of military colony of the USSR.

What is possibly less known is that also Soviet nuclear weapons were stationed in some satellites of the USSR, like the GDR (see this and this chapters, for instance), Hungary (see this chapter), and of course Poland.

Some elements of the global picture have been introduced in another chapter, dealing among other things with a Basalt-type bunker built for storing air-launched nuclear systems, on the premises of the Soviet airbase of Wiechlice (Szprotawa). Yet as can be argued from the general map of of nuclear depots known to Western intelligence, dating from 1979 (‘Warsaw Pact Forces Opposite NATO’, Vol.I-II, CREST record number 0005517771, declassified and released in 2010, here), there were also three major depots of the Monolith-type in Poland. Similar to Stolzenhain and Lychen in the former GDR (see this post), these depots were larger, multi-chamber storage facilities, intended to store primarily missile warheads for longer periods, for instance to complement the SCUD launch system for theater missiles.

The uniqueness of Poland in the panorama of Cold War archaeology lies in a generally positive attitude towards preserving some traces of this dramatic piece of recent history, when the map of Europe was markedly different from now, and the western world found itself multiple times on the verge of a nuclear confrontation, to be fought on the very territory of now wealthy Core Europe. As a result, an impressive number of war museums putting on display military stuff from all the 20th century can be found scattered over the broad territory of today’s Poland.

Even more important, a certain number of former Soviet military installations are being either actively preserved, or at least not condemned through demolition works or re-assignment to improbable new uses. This is despite a totally justified negative attitude towards the Soviet occupation forces and communist dictatorship. This attitude marks an unusual difference between the cultural attitude of the fierce Polish people towards recent military history and Soviet occupation, with respect for instance to Germany or Hungary, where the comprehensible dislike for the Soviets has taken a shape in leaving behind – i.e. more or less demolishing – every trace of a Soviet military presence, and especially in the former, reducing military museums to a minimum.

Among the most prominent Cold War relics you can find in Poland are the three Monolith-type nuclear warhead bunkers mentioned above. One of them – the Podborsko site – has been restored with 90% original material, and makes for a world-class, top-tier museum in the panorama of Cold War military history. The other two, Brzeznica-Kolonia and Templewo, have been left to nature and have now become ‘Soviet ghosts’, but they are advertised with panels, providing some info, and while access is not encouraged, a quick look inside the bunkers, as well as freely walking in the former premises of these bases, is of course possible.

This post covers these three Monolith-type sites, with a focus on the unique preserved Podborsko site, which needs to be on the shortlist of everyone with an interest in Cold War technology, as well as in the history of the nuclear stockpile. All sites were visited, and all photographs taken, on a trip to western Poland in summer 2020.

Sights

All three sites are in northwestern Poland. GPS coordinates are provided in the respective sections. Despite being not too much afar from each other, due the relatively slow connection roads in the area, visiting all three places in one day is not possible. Furthermore, the area is quite dense in both general interest and Cold War related destinations, so I would advise planning a trip to this region of Poland and listing these sites among other destinations.

Podborsko Site – Objekt 3001

A good specimen of a Monolith site, Podborsko – or Objekt 3001, as per the official military listing of the Cold War years – was centered on two large half-interred bunker, each with two big side-wards opening tight doors at ground level, providing access to the interior with the trolleys used to move the nuclear warheads from the transport trucks to the cellars.

For an increased protection in case of an attack to the site – likely listed among targets of strategic value by Western Countries – a second tight door was put immediately next to the external one, creating a tight, blast resisting and insulated airlock between the interior of the bunker and the outside world.

Both doors to the two ends of the airlock can be – and are – opened via a manual crank system. Two men are needed to actually move the doors however – they are really heavy! A servo-assisted system was in place originally.

An interesting detail is the original sensor for the door status, part of a security system of the base.

Similar to their US counterparts, the Soviets took the problem of security of the nuclear arsenal pretty seriously. Each door on the path followed by the warhead from the outside to the cellar, including the airlock doors as well as the cellar doors inside the bunker, were associated to a trigger. When the corresponding door was opened, the trigger sent a signal via a dedicated cable link to the headquarters of a dedicated branch of the Red Army offices in Moscow, Russia, which was kept constantly updated on the status of each critical door in the depot. The link was via purpose-designed vacuum-protected cables – the actual wiring ran along a vacuum manifold, so that in case of the cable was bitten and the vacuum manifold collapsed, an emergency signal was immediately sent to the nearest nodes of the network, allowing surveillance staff to intervene promptly.

The opening of and closing procedure of the airlock doors involved communication with a post in Moscow too, which started with the local guards communicating their intention to open the doors via a system housed in a blue cabinet besides the tight door. As the signal traveled from the bunker to the headquarters and back, the opening of an airlock was not a quick operation! Original writings in pencil can still be found in the cabinet.

Past the airlock, you land on an elevated concrete platform. From here the warheads were moved to the underground floor via a mechanical crane. This is still standing today, with limit indications in Russian.

From the platform you get an excellent lookout of the bunker structure. You can see a twin suspended platform to the opposite end of the underground floor, with a tight door shut closed. Along the long sides of the main hall, on the underground level you see several doors. On the right hand side, big sliding doors painted in white give access to the cellars, where the warheads spent most of their time in rest. On the opposite side are smaller man-sized doors, giving access to the technical area, with provision for the men of the permanent bunker watch.

The stairs leading downstairs are among the few complements to the original structure – they have been put in place to ease visiting. Originally, the underground floor could be reached from the suspended platform only via a lateral manhole with a vertical metal latter.

The warheads are long gone today – the site was built in the late 1960s, and was emptied of its strategically relevant content in the late 1980s, to be finally ceded back to the Polish government after the withdrawal of all Russian forces from Europe. The cellars today are mainly empty, and used to showcase interesting items related to the site.

First, you can see a scale model of the entire site. In Soviet times, the place was a full scale military base. It included a separated area with living facilities for the troops and their families, who ran the base with both technical and surveillance tasks. Today, this area has been taken over by the government, and used as a prison – Podborsko is rather secluded and far from populated areas on the Baltic coast. Furthermore, as said there used to be two twin bunkers. Today only one has been restored, whereas the other is sealed and waiting for reuse. Between the sectors of the base multiple fences with barbed wire, concrete walls, foxholes and other deterring/defense devices and systems were in place, making the innermost part of the base with the bunkers rather inaccessible.

An original armored cabinet from the time of operation is still in the corner of a cellar, its original use is uncertain.

In another cellar you can find everyday items and relics from Soviet presence in the area. These range from toothpaste to children’s toys. Also more military-related items, like cartridge boxes and even original Soviet military dog tags have been found scattered over the area!

You can also find weapons, a scheme of the base in Russian, anti-radiation suits, and parts of the body, control and guidance systems of a Soviet SCUD theater missile – the corresponding warheads being the main business in Podborsko. There is also a copy of the plan of an attack scenario for Western Europe, showing some targets on the respective sides of the Iron Curtain.

One of the cellars has been left empty, with a mock-up of a warhead, resting on one of the original trolleys. This is particularly evoking, despite being just one out of the high number of warheads usually stored in a cellar. The actual number of warheads residing in each Soviet storage over the years is still today not totally clear. However, reportedly former Soviet staff support there was in a single Monolith bunker in Poland enough nuclear material for the whole attack plan over Europe, meaning a number of several tens warheads per site.

The trolley is original as said, and it shows the function of the slots on the ground of each cellar, which allowed anchoring the trolley firmly in position. This was possibly needed also in the extreme case of a blast hitting the bunker, so as to avoid any unwanted displacement of the trolleys.

A fourth cellar displays a set of panels, outlining the history of the Cold War.

As said, the security triggers telling the status of the door can be found close also to each of the sliding doors of the cellars.

Before moving to the technical area on the other side of the bunker, a look to the central hall reveals a number of original material. In particular, you can find an interesting set of instruments, handles and gauges packed together in a metal cabinet. Their function was that of monitoring the state of each warhead. Nuclear material needs to be stored in precise conservation conditions, so warheads were kept in dedicated cases. These were inspected regularly by connecting them to the monitoring system and recording the corresponding gauge readings. Traces of the positioning markers for an inspected trolley can be found close to the cabinet, painted on the ground.

Another conspicuous sight in the main hall is the heating system, needed to keep the inside atmosphere at a constant assigned temperature and humidity level, to guarantee the health of nuclear material. A big array of heat exchangers takes the top part of a side wall in the main hall.

The technical part is made of two main parts, and is accessible on the long side of the hall opposite to the cellars. One part is made of a blind sequence of three narrow compartments. Here you can find a case for manipulating dangerous chemicals, with protection gloves once protruding inside. Nearby, a sink and some cabinets recall a medical room.

This area was designed to manipulate and check the triggers of nuclear weapons in use at the time of construction of the Monolith bunkers (late 1960s). These made use of reactive materials, thus requiring some precautions and a complex maintenance procedure. They were phased out soon after the construction of the site though, so this part of the bunker was basically unused since that time. A tight door connects this area to the main hall.

The second part of the technical area is arranged along a U-shaped corridor, starting and ending in the main hall. Similar to the previous technical part, a small sealed door connects the corridor to the main hall.

The first technical rooms you meet are related to climate control.

Next you find a big water tank. Close by there is a single toilet. This was reportedly seldom used, as drainage did not work properly due to the underground placement. Watchmen during their shifts in the bunker went out for their physiological needs.

Going in and out for pedestrians was made possible through a man-sized airlock. This is perfectly preserved in Podborsko, similar to the passage leading up, by means of very steep metal ladders.

Another interesting sight in the technical area is the air filtering room, which is close to the small living area for the watch staff. In case of an attack to the facility, making the area poisonous possibly also due to fallout, this huge filtering system allowed the troops inside to survive for some time.

The electric control room is in almost mint condition. Only the major connections to the external power lines – not there any more – have been cut. Same electric connections still bear their original hand written identifiers!

An original – and rare – handbook with some illustration of standard trolleys is among the artifacts to be found in this incredible exhibition.

Concluding the technical part, a massive Diesel power generator, with its ancillary air pumping and exhaust expulsion systems, is still there in a rather good state.

Back outside, the Podborsko site features also a Granit-type bunker, perfectly preserved with its metal doors – seldom found elsewhere. Granit bunkers were much softer in construction than the Monolith-type, and they might be used for storing assembled missiles, command posts and more. The one in Podborsko is another Soviet mystery – it is hard to tell to what purpose it was built, probably in the late 1970s-early 1980s.

The second bunker, very similar inside to the main one, is sealed and waiting for restoration. You can walk the exterior, where some remains of the truck loading/unloading platforms can be found. Traces of a fence line can be seen to the back.

Getting there and moving around

The Podborsko site is a branch of the ‘Muzeum Oreza Polskiego w Kolobrzegu’, called ‘Cold War Museum Podborsko 3001’ (‘Muzeum Zimnej Wojny Podborsko 3001’ in Polish). The town of Kolobrzeg is on the Baltic coast, roughly a one hour drive from this bunker, and hosts other branches of this nice museum (a tank and artillery collection, a marine branch,…). The dedicated website of Podborsko is here, to be Google-translated from Polish. The Podborsko site is open on a regular basis at least in summer, and also by appointment. I guess the visit may take about 1 hour once on site.

My visit was a special one though, as I had the chance to join in for a special thorough visit of the site, prepared for Dr. Reiner Helling, a nuclear scientist from Germany, and one of the most knowledgeable historians in the field of Soviet military presence and nuclear assets in Europe. Dr. Helling extended the invitation to me, so I had the unique chance to take a private, tour with the local curators of the branch, Mr. Mieczysław Żuk and Mr. Pawel Urbaniak. We spent some hours touring the site inside and out – special thanks to all three for an unforgettable experience!

Getting to the bunker is easy by car. Driving will be along an original Soviet service road, which can be faced with a regular city car. You may park once on the spot once there.

Brzeznica Kolonia – Objekt 3002

The site in Brzeznica Kolonia can be found close to the former Soviet village of Klomino – pretty famous in its heyday among the urbex community – and in the vicinity of the airport of Nadarzyce, still active today.

The site has been largely wiped out, but the bunkers and a little more hardware survive, in a ghost condition. However, the site is advertised with some explanatory panels, and it is also quite popular among the locals, which come here to take a couple of pics in a weird scenery.

One of the most portrayed items on the premises of this site is the Granit bunker, which is today lacking its original metal door. Similar to Podborsko, this ‘soft’ bunker was added at a later stage, and its function is to be guessed. Interestingly, some painted stripes can be found on the pavement, possibly marking the position of some trailer or gear.

Similar to Podborsko, the two major Monolith bunkers are arranged with their respective axes crossed. The eastern one can be accessed from its southern door pretty easily. Inside, it reveals its similarity with Podborsko, except for having being spoiled of any metal part – from the doors to the heat exchangers – and having hosted a wildfire or similar, as can be guessed from the sooth on the walls and ceiling.

Getting to the underground level from the suspended platform is not safe if you are going alone, like me, as the original metal ladders have been taken away. However, hard spoiling has to be expected also in the technical rooms.

Walking on top of the bunker, you find traces of the man-sized side entrance, completely interred.

Ahead of the bunker and to the back, traces of the loading/unloading platforms for trucks can be still recognized.

The westernmost bunker is easy to access from the eastern gate. Inside, it has been spoiled of any metal, similar to its twin brother. It is in a generally better shape though, without sooth on the inside walls.

In both bunkers, traces of original painting can be found.

In between the two bunkers, a number of smaller buildings are still to be found, including – apparently – a water tank, and some sentry boxes.

Also, more than in Podborsko you can appreciate a network of foxholes, which despite fading in nature, can be clearly noticed departing from the main roads once crossing this military installation.

Back to Nadarzyce nearby, you can get access to the former ghost town of Klomino. The majority of the original Soviet blocks have been wiped out, but most incredibly some of them have been restored and are today inhabited. This, and the very bad access road, make this place worth a visit only for completing the tour of this once big Soviet installation, without adding much. There is really not much left to see in Klomino.

Getting there and moving around

As said, the bunkers are pretty popular among the locals, who go there by mountain bike or car. The site can be accessed via an unpaved service road, totally safe also for a standard car, taking south from Nadarzyce. The parking point is here 53°25’51.0″N 16°34’43.6″E. There are also some picnic tables, an explanatory panel and some warning signs.

Templewo – Objekt 3003

Similar to Brzeznica Kolonia, the Templewo site has been largely reclaimed, and is now partly preserved as an unusual spot in the wilderness. The base has completely gone, but the the monolith bunkers are still there.

They can be found following an original Soviet paved road.

Both Monolith-type bunkers can be accessed with little difficulty, despite the gates having being mostly interred, like for Objekt 3002.
