The museum is located in one of the largest batteries from the Second World War in Northern Europe, part of the fortification system known as the Atlantic Wall. In addition to the partially reconstructed interior, you can see an exhibition devoted to World War II and the life of the soldiers who operated the battery.
The battery was built in 1941. It consisted of 4 large 38 cm guns. Each of them weighed 110 tons, and their range was 55 km. The guns were protected by a 3.5-meter layer of reinforced concrete and smaller anti-aircraft guns.
When visiting the museum, you can also take a ride on the museum's narrow-gauge railway. The route is 1 km long and leads around the battery along the original tracks used during the war to transport heavy ammunition. The tour takes approximately 10 minutes.
