The Cold War left an indelible mark on Europe’s landscape. Thousands of military installations were built to prepare for a conflict that never came. These concrete monoliths now stand as eerie time capsules, preserving the tension and paranoia of an era when nuclear annihilation seemed just minutes away. Many of these once-secret facilities have been repurposed as museums or tourist attractions, offering a fascinating glimpse into a not-so-distant past when the world teetered on the brink.
Here is a list of 20 abandoned Cold War bunkers across Europe that you can still visit today.
Bunk’Art (Albania)
Enver Hoxha’s massive underground complex beneath Tirana was designed to house the entire Albanian government in case of a nuclear attack. The five-story, 106-room bunker has been transformed into an art space and history museum that opened in 2014.
Visitors can explore the eerie network of tunnels while learning about Albania’s communist past through exhibitions that don’t stop depicting the harsh realities of life under a dictatorship.
Kelvedon Hatch (United Kingdom)
This former Regional Government Headquarters in Essex was designed to house 600 officials after a nuclear strike. The bunker descends three stories underground and features original equipment, including communication systems, dormitories, and even a BBC broadcasting studio.
Walking through its chilly corridors with an audio guide offers an unsettling reminder of how close Britain came to implementing its apocalyptic contingency plans.

Bunker 42 (Russia)
Located 213 feet beneath Moscow’s streets, this massive 75,000-square-foot facility was built to withstand a direct nuclear hit. The bunker operated as a command center for the Soviet strategic air forces, with enough supplies for 3,000 people to survive for months.
Today, visitors can tour this Cold War relic, which includes preserved communication equipment, gas masks, and an interactive missile launch simulation that recreates the tension of a potential nuclear conflict.
Hospital in the Rock (Hungary)
Built within the natural cave system beneath Buda Castle in Budapest, this facility was a hospital during WWII and a nuclear bunker during the Cold War. The six-mile labyrinth of tunnels contains original medical equipment and eerily lifelike wax figures depicting hospital scenes.
Guided tours take visitors through rooms where surgeons once operated by candlelight and where thousands would have sought shelter had nuclear war broken out.
Sonnenberg Bunker (Switzerland)
Switzerland’s largest civilian shelter was built to protect 20,000 people in the event of nuclear war. The massive facility includes a fully equipped underground hospital, sleeping quarters, and a morgue for the anticipated casualties.
Due to ventilation problems discovered during testing, the bunker’s occupancy was later reduced to just 2,000 people, making it a $40 million testament to the miscalculations of Cold War planning.

Bunkermuseum Frauenwald (Germany)
This East German command bunker near the town of Ilmenau was designed to coordinate military operations during a nuclear war. The three-story underground facility could house 120 personnel for weeks, complete with its power generation, water supply, and air filtration systems.
Visitors can now explore the restored command rooms, communications center, and sleeping quarters, representing a perfectly preserved example of Soviet-bloc military preparedness.
Balaklava Submarine Base (Ukraine)
Carved into a mountainside in Crimea, this top-secret facility could shelter up to seven submarines from a nuclear blast. The underground complex included channels for submarines to enter undetected, repair facilities, and living quarters for 1,500 personnel.
Now a naval museum, visitors can walk through the nuclear-proof tunnels, which were built to withstand a direct hit equivalent to five Hiroshima bombs.
York Cold War Bunker (United Kingdom)
This relatively small but perfectly preserved bunker in northern England was monitored for signs of nuclear attack from 1961 to 1991. The semi-underground structure was designed to house 60 volunteers from the Royal Observer Corps who would track radioactive fallout.
Complete with original equipment, dormitories, and a canteen stocked with 1980s supplies, it offers an intimate look at the human dimension of Cold War vigilance.

Harnekop Bunker (Germany)
This massive East German government facility was built to maintain communist control after a nuclear strike. Hidden in the forests north of Berlin, the three-story underground complex could support 400 officials for several weeks.
The bunker’s command center, sleeping quarters, and air filtration systems remain largely intact, providing a glimpse into East Germany’s cold calculation that governance could continue even after nuclear devastation.
Konjic Bunker (Bosnia and Herzegovina)
Known as ARK, this massive facility was Yugoslavia’s greatest state secret. It was built to shelter President Tito and 350 political elites. The U-shaped complex, carved into a mountain, spans 280,000 square feet and costs the equivalent of $4.6 billion today.
Now repurposed as an art gallery and museum, visitors can explore the residential areas, conference rooms, and offices where Yugoslavia’s leaders planned to wait out the nuclear winter.
Teufelsberg (Germany)
Built atop an artificial World War II rubble hill in Berlin, this NSA listening station intercepted Eastern Bloc communications throughout the Cold War. The distinctive white radar domes housed sophisticated equipment that could capture signals from hundreds of miles away.
Now covered in striking street art, the abandoned facility offers historical insight and panoramic views of Berlin from its highest tower.

Stalin Line Bunkers (Belarus)
This defensive line of fortifications stretches across Belarus and contains dozens of accessible bunkers and artillery positions. Originally built in the 1930s to defend against Nazi invasion, the bunkers were repurposed and expanded during the Cold War.
Visitors can now explore these concrete capsules of Soviet military history while examining period weapons, vehicles, and equipment at the open-air museum complex.
Stevensfort Cold War Museum (Denmark)
Built into the cliffs of eastern Denmark, this NATO outpost monitored Soviet naval activity in the Baltic Sea from 1953 to 2000. The facility’s massive underground network includes a hospital, living quarters, and a command center carved directly into limestone.
For many visitors, the highlight is the long underground tunnel leading to the gun battery, where massive artillery pieces still point silently toward imagined Soviet invaders.
Fallout Shelter 10-Z (Czech Republic)
Originally built as a World War II air raid shelter in Brno, this facility was converted into a nuclear bunker for city officials during the 1950s. The shelter could accommodate 500 people with air filtration systems, telecommunications equipment, and water supply.
Today’s visitors can experience spending a night in the bunker with period furnishings or simply tour the facility to understand the psychological reality of Cold War preparedness.

La Rochelle Bunker (France)
This massive concrete structure was a German U-boat base during WWII before being repurposed for Cold War defense. Its 26-foot-thick roof was designed to withstand heavy aerial bombardment, making it equally suitable for nuclear protection.
Visitors today can explore the cavernous submarine pens while learning how military infrastructure was repurposed across multiple conflicts throughout the 20th century.
Silkeborg Bunker (Denmark)
This former Nazi headquarters became Denmark’s most important Cold War command center after World War II. The sprawling underground complex could house hundreds of military personnel and government officials in the event of a nuclear war.
Original maps, communication equipment, and situation rooms remain in place, allowing visitors to understand how Danish military leaders planned to coordinate national defense during the apocalypse.
Gotland Coastal Artillery Batteries (Sweden)
Sweden’s strategically important island of Gotland is home to numerous coastal defense bunkers that remained operational until the 1990s. These concrete fortifications housed artillery capable of engaging Soviet naval forces attempting to control the Baltic Sea.
Now abandoned but accessible, these bunkers offer stunning coastal views alongside a tangible connection to Sweden’s officially neutral but practically Western-aligned Cold War stance.

Kőbánya Bunker (Hungary)
Built within a former limestone mine beneath Budapest, this facility served as a wartime hospital and, later, a nuclear shelter. The massive underground complex spans over ten miles of tunnels with natural temperature regulation suitable for long-term occupation.
The bunker gained renewed purpose after the 1956 Hungarian Revolution when Soviet authorities expanded it to shelter thousands in case Western retaliation turned nuclear.
Gjirokastra Tunnel System (Albania)
The paranoid Albanian regime constructed an extensive tunnel network beneath this UNESCO World Heritage city to shelter its population from potential invasion. Every neighborhood had access points to this underground labyrinth, which included living quarters, storage facilities, and defensive positions.
Local guides now offer tours of portions of this 741-mile network, explaining how ordinary citizens were expected to transform into resistance fighters if an invasion came from the East or West.
Hack Green Secret Nuclear Bunker (United Kingdom)
This former radar station was converted into a Regional Government Headquarters designed to coordinate survival after a nuclear attack. No longer ‘secret,’ as its tongue-in-cheek name suggests, the facility now houses one of Britain’s largest Cold War museums, with original equipment and realistic mannequins.
The bunker’s blast doors, decontamination chambers, and operations rooms provide a meticulously preserved time capsule of Britain’s nuclear civil defense preparations.
