U-Boat Bunker Keroman K3

A military bunker located near Lorient, France, the U-Boat Bunker Keroman K3 (K3) is part of the extensive submarine base constructed by Nazi Germany during World War II. Built as part of the Atlantic Wall defenses, this massive concrete structure was designed to protect U-boats from Allied air raids and served as a critical naval facility for the Kriegsmarine. The bunker stands as a stark reminder of the region's strategic importance during the conflict and the industrial scale of wartime fortifications along the French Atlantic coast.
