Naval Gun Battery Hysnes

Hysnes fort was built by the Norwegian defense in 1897 and consisted of 210 mm. guns. The guns were supposed to protect the entrance to Trondheim and on April 9, 1940, the gun battery opened fire on the attacking Germans. A power outage, however, stopped the battle and the Germans could land troops in Trondheim.

During the war, the Germans modernized the gun battery and built a large Fire control post (M157). After the war, the Norwegian defense took over the gun battery and it remained operational until 1998.

Today, a small museum has been set up on site.
