Hambåra Fortress, also known as Hambåra Fort, is a historical structure located in Agdenes Municipality, Trøndelag County, Norway. It was initially part of the Agdenes fortifications, also known as Agdenes befestninger, which were built in the 1890s to defend the Trondheimsfjord and Trondheim against potential enemies.
Constructed on a steep hillside near the Agdenes Lighthouse, it never witnessed significant combat throughout its history. During the German invasion of Norway in April 1940, it was unoccupied by Norwegian forces. German troops subsequently took over the site and reinforced it with additional defenses, including a torpedo battery. It remained under German control throughout World War II.
Following the war, the Norwegian Armed Forces utilized Hambåra Fortress until the 1950s or 1960s when it was ultimately decommissioned.
