OB 8.8cm Flak is a World War II-era anti-aircraft bunker located in northern Norway. This concrete fortification was part of the German Atlantic Wall defensive system, designed to protect against Allied air attacks. The bunker housed 8.8cm Flak (Flugabwehrkanone) anti-aircraft guns, which were among the most effective artillery pieces of their time.
Situated in a strategic coastal location, this bunker formed part of Norway's extensive network of military fortifications during the German occupation.
