Langeland Fort was built all the way back in the 1950s. The fort was built with cannons, underground bunkers and anti-aircraft positions. During the Cold War, it was important to be able to keep an eye on the Warsaw Pact's air and naval activities, and this was done from Langeland Fort. Today it is a museum, with stories and tales from that time. At the museum, you can see a MIG-23 fighter plane, a minesweeper, a submarine and a complete section of the Berlin Wall. These experiences take place both underground and above ground, which makes it a very special experience for visitors. The Cold War Museum is not the only exciting museum on Langeland. You can also visit Fiskeriets Hus, which contains the history of fishing, or Langeland Museum, where you can see and read about ancient finds from Langeland and Strynø.
