OB 8,8cm Flak is a coastal artillery bunker located in northern Norway, near the town of Berlevåg. This defensive structure was part of the German Atlantic Wall fortifications built during World War II to protect Norway's strategic coastline. The bunker housed anti-aircraft artillery, specifically 8.8cm Flak guns, which were originally designed for air defense but proved highly effective against ground targets.
Norway's occupation by Nazi Germany from 1940 to 1945 saw the construction of numerous such fortifications along the coast, forming an extensive network of military bunkers and gun emplacements.
