The Rödberget fortress was built between 1900 and 1916 in the mountain area surrounding Boden. It consists of 5 mountain forts, 3 smaller fortifications, individual artillery batteries and 40 bunkers. Inside the fortress there was a command center, underground ammunition and fuel warehouses, and a small airport. The complex forms a circle around the entire city.
The main goal of Rödberget was to defend against an attack by the Russian army, and then by the USSR, against an attack from the territory of Finland. The fortress was also supposed to be a protection against attacks from the Gulf of Bothnia. After the end of the Cold War, the fortress lost its importance and was gradually abandoned. The last fort was withdrawn from use at the end of 1998. Currently, the fortress has the character of a monument and is open to the public.
