OB 10.5cm Flak is a German-built World War II anti-aircraft bunker located in France, part of the extensive Atlantic Wall fortifications. This type of bunker was designed to house 10.5 cm anti-aircraft guns, providing defensive coverage against Allied air raids during the German occupation. The structure represents the military engineering efforts of Nazi Germany to fortify the French coastline against potential invasion.
Today, it stands as a historical relic of the wartime occupation and the broader Atlantic Wall defensive system.
