Once a top-secret fortress in the chalk cliffs of Stevns, this Cold War stronghold now reveals tunnels, guns and Baltic views from NATO’s former frontline.

4.5

Built deep into the chalk cliffs above the Baltic Sea, the Cold War Museum Stevnsfort is a former top-secret NATO fortress turned immersive history museum. Eighteen metres underground, more than a kilometre of tunnels, command rooms and gun emplacements reveal how Denmark monitored the Baltic and prepared for nuclear conflict. Above ground, missile batteries, radar gear and Baltic views complete a compelling journey into Europe’s tense Cold War frontline.

Local tips

  • Wear warm layers and sturdy shoes: the underground fort stays around 10°C year-round and involves several kilometres of walking on sometimes slippery floors.
  • Plan several hours to explore both the underground complex and outdoor terrain, taking breaks at the visitor centre or roof terrace between sections.
  • If travelling with young children or visitors with limited mobility, be aware that strollers are not allowed underground and parts of the tunnel system have restricted access.
  • Bring your own picnic to enjoy at the outdoor tables and benches, then use the museum shop for hot and cold drinks, ice cream and small snacks.
  • Allow time to walk the cliff-top grounds around the artillery and missile displays; the Baltic Sea views help put the fort’s strategic position into perspective.

Getting There

  • Regional train and local bus from Copenhagen

    From central Copenhagen, take a regional train toward Køge and connect to the local line to Rødvig; the full rail journey typically takes 1.5–2 hours. From Rødvig station, a local bus or taxi covers the remaining few kilometres to the museum in around 10–15 minutes. A combined one-way public transport trip using standard tickets usually costs in the range of 120–170 DKK per adult, depending on time of day and ticket type. Services run regularly during the day, but frequencies may be reduced on weekends and public holidays, so check schedules in advance.

  • Car from Copenhagen and Zealand

    Driving from central Copenhagen to the Cold War Museum Stevnsfort typically takes about 1–1.5 hours, depending on traffic and the chosen route across Zealand. The journey uses good-quality main roads almost the entire way, with the final stretch on smaller country roads toward the coast. Parking is available by the museum and is usually free or low-cost, but spaces can fill up in peak summer periods and during Danish school holidays. Fuel costs for the round trip from Copenhagen are roughly 150–250 DKK, depending on vehicle size and fuel prices.

  • Cycling from Rødvig and Stevns area

    For active travellers staying in or near Rødvig, cycling to the museum offers a scenic approach through gently rolling countryside and coastal views. The ride from Rødvig town typically takes 15–30 minutes each way at a relaxed pace, using local roads that are generally quiet but may have sections without dedicated bike lanes. The terrain is mostly easy, with only mild inclines, and standard city or touring bicycles are sufficient. This option is free aside from any bicycle rental, which in the region often ranges around 100–200 DKK per day depending on the provider.

A secret fortress in the chalk of Stevns

Carved into the white limestone cliffs near Rødvig, the Cold War Museum Stevnsfort was once one of Denmark’s most secret military installations. Conceived in the early 1950s at the height of Cold War tension, the fort guarded the narrow entrance to the Baltic Sea, monitoring any movement between the Warsaw Pact and NATO. Today, the camouflage has been stripped away, but the sense of secrecy lingers in every concrete corridor and heavy blast door. Above ground, the coastal setting feels almost peaceful: grassy ramparts, scattered bunkers, radar masts and hulking artillery pieces framed by big Baltic skies. It is only when you learn that this calm landscape was designed to withstand nuclear shockwaves that the site’s true purpose comes into focus.

Life on NATO’s Baltic frontline

Stevnsfort was built to keep watch over a strategic maritime chokepoint, tracking ships and aircraft and feeding information into NATO’s defence network. Several hundred soldiers could be sealed inside the underground complex for weeks, supported by their own power, ventilation, water and supplies. Here, they would have continued working even in the event of a nuclear strike, guiding artillery, missiles and radar from behind thick layers of chalk and reinforced concrete. Displays in the exhibition areas explain how Denmark’s defence strategy evolved during the Cold War, from conventional artillery to guided missiles and sophisticated listening equipment. Maps, models and original instruments show how the fort’s crews tracked potential enemies and coordinated with other bases to protect Copenhagen and the wider Baltic region.

Descending into the underground maze

The heart of Stevnsfort lies 18 metres below ground. A long flight of stairs, or an elevator, leads into a network of tunnels and rooms stretching well over a kilometre. Down here, the temperature sits around 10°C year-round, and the air feels cool and faintly damp, a reminder that you are walking through excavated limestone. Along the way you pass operations rooms filled with dials and switches, communications centres with heavy phones and cipher equipment, and living quarters where soldiers slept, ate and tried to carve out a semblance of normal life. The narrow corridors, low ceilings and constant hum of machinery hint at the intensity of working in a sealed fortress designed to withstand chemical, biological and nuclear threats.

Guns, missiles and machines above the cliff

Back on the surface, the fortress becomes a vast open-air gallery of Cold War hardware. Massive 150 mm gun turrets once capable of striking targets across the Baltic dominate the grounds, their barrels still pointing seaward. Nearby, missile launchers, radar dishes, searchlights and armoured vehicles stand in neat rows, allowing you to trace the technological leap from coastal artillery to guided air defence. The terrain invites unhurried wandering: you can study the details of a missile battery, peer into bunkers, or simply stand on the edge of the cliff and imagine ships passing under the gaze of Stevnsfort’s hidden sensors. Information panels help interpret the machinery without disturbing the windswept, slightly austere atmosphere that suits the site’s military past.

Visiting practicalities and pace

The museum combines indoor exhibitions, extensive outdoor grounds and a substantial underground component, so a visit rewards comfortable footwear and layered clothing. Most visitors spend several hours moving between the surface installations, the visitor centre’s displays and the lengthy underground route. The tunnels involve walking several kilometres at a steady pace, and the stairs are long and relatively steep, though an elevator helps some visitors reach the underground level. Facilities at the entrance building and in the grounds make it easy to pause between sections of your visit, with places to sit, toilets and options for drinks or a simple snack. On a clear day, lingering on the roof terrace or at one of the outdoor tables offers a curious contrast: a relaxed break above a fortress that was once designed to face the worst imaginable scenarios of 20th-century conflict.

A human story behind concrete walls

Beyond hardware and strategy, Stevnsfort is also a story of everyday life lived under the shadow of global tension. Personal objects, photographs and reconstructed rooms suggest how conscripts and officers coped with long shifts, training drills and the knowledge that their workplace would have been a primary target in any war. The museum’s exhibits frame the base not only as an engineering achievement, but as a workplace where people served, socialised and planned for a disaster everyone hoped would never come. Taken together, the cliff-top setting, preserved tunnels, and intact equipment make the Cold War Museum Stevnsfort a rare opportunity to step inside the mindset of the Cold War era—an immersive snapshot of a time when this quiet corner of Zealand stood on the frontline of a divided world.
