Discover Stevnsfort on a very special 2-hour guided tour that opens doors normally closed to the public. On Saturdays in September and October 2026, you’ll gain access to parts of the underground fort that very few people have ever seen—a fort located in the heart of Stevns Klint, a UNESCO World Heritage Site.

This tour delves into the details. The story of control over the Baltic straits and surveillance during the Cold War is explored in greater depth than on the standard tour—and you’ll visit a few nooks and crannies that are otherwise skipped. You’ll walk along the long 40-millimeter corridor leading to the southern anti-aircraft battery and step into Oliegade—the fort’s secret fuel depot, where, during the darkest hours of the war, the tank roofs could be used as an extended mortuary.

Stevnsfort is one of Denmark’s most fascinating Cold War museums and a must-see in East Zealand. As the guardian of the Baltic Sea, the fort was at the heart of Denmark’s and NATO’s defense against a potential invasion by the Warsaw Pact—and here you can truly feel history firsthand, surrounded by one of the world’s most remarkable natural coastlines.

Our knowledgeable guides bring to life the grand narratives of security policy, turbulent times, and the people behind the walls—rooted in the fort’s authentic buildings, equipment, and history. It’s living history that leaves a lasting impression.

Your ticket also gives you access to the entire fortress grounds for the rest of the day during the museum’s opening hours—pack a picnic and enjoy lunch outdoors with a view of the World Heritage Site. There are plenty of tables and benches.

We recommend that you reserve your spot well in advance—the tours tend to sell out! The underground fortress can only be explored on a guided tour.
