Northern Norway suffered greatly in the early years of World War II. Learn the details of the dramatic sinking of Tirpitz, the giant German battleship that kept the British Royal Navy in the region busy for three years. The museum is not located in town, but at the site of a Nazi coastal artillery battery with two 10.5-cm cannons and a restored command bunker with operational equipment. The museum also covers the history of other wars in the region dating back to the 13th century.
