Kvænangen concentration camp was established in the municipality of Kvænangen in Northern Norway by the Nazi administration of occupied Norway in August 1942, as annex to Grini. It consisted of two subcamps, Veidal and Badderen, which was also known as Veiskaret. The camp remained open until 11 November 1942, during which time about 400 prisoners were put to slave labor building a shelter over 6 km of road in the area. The shelter was known as "Norway's longest" wooden house.
