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.

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.
