OB 7,5cm Flak (f) is a World War II-era German military bunker located in southern France. This coastal defense structure was part of the Atlantic Wall fortifications built by Nazi Germany to defend occupied territories against Allied invasion. The bunker housed a 7.5cm Flak (Flugabwehrkanone) anti-aircraft gun, designed to protect against aerial attacks and provide ground defense.
Situated in the Provence-Alpes-Côte d'Azur region, this fortification represents the extensive military infrastructure constructed along the French Mediterranean coast during the German occupation.
