OB 2cm Flak is a former German-built anti-aircraft bunker located in northern Norway, near the coast of the Norwegian Sea. Constructed during World War II as part of the German occupation's coastal defense network, this bunker was designed to house a 2cm Flak (Flugabwehrkanone) anti-aircraft gun, intended to protect nearby installations and shipping lanes from Allied air attacks. The structure exemplifies the Regelbau standardized bunker designs used extensively along the Norwegian coast during the war.
Today, the bunker stands as a historical relic of the wartime occupation, with its thick concrete walls and strategic coastal position still visible in the rugged Arctic landscape.
