OB 2cm Flak is a former anti-aircraft bunker located in northern Norway, near the coast of the Norwegian Sea. Built during the Cold War era, this bunker was part of Norway's extensive coastal defense network designed to protect against potential Soviet air threats. The site features reinforced concrete construction typical of the period, with strategic positioning to cover maritime approaches.
Like many Norwegian Cold War installations, it has been preserved as part of the country's military heritage, reflecting the region's strategic importance during decades of East-West tensions.
