OB 10.5cm Geschütz is a German World War II coastal artillery bunker located in Brittany, France. This fortification was part of the Atlantic Wall defenses constructed by Nazi Germany to protect occupied France from Allied invasion. The designation 'OB' typically refers to an 'Offene Bauart' (open construction) bunker, while '10.5cm Geschütz' indicates it housed a 10.5cm gun battery.
Situated along France's strategic Atlantic coastline, this bunker represents the extensive military engineering efforts undertaken by German forces during their occupation of France from 1940 to 1944.
