OB 10.5cm Geschütz is a World War II-era German coastal artillery bunker located in southern France, near the Mediterranean coast. This type of emplacement was part of the Atlantic Wall defensive system constructed by Nazi Germany to protect occupied territories from Allied invasion. The bunker housed a 10.5cm naval gun, designed to engage enemy ships and provide coastal defense.
Its strategic position allowed for wide-ranging fire over the Mediterranean Sea, contributing to the broader network of fortifications along the French coastline during the war.
