OB 7,5cm Geschütz is a German World War II-era artillery bunker located in France, part of the extensive Atlantic Wall fortifications built along the French coastline. This type of bunker was designed to house a 7.5 cm anti-tank or field gun, providing defensive firepower against Allied naval and ground forces. The Atlantic Wall was a massive system of coastal defenses constructed by Nazi Germany between 1942 and 1944 in anticipation of an Allied invasion.
OB 7,5cm Geschütz bunkers were typically built to Regelbau (standard design) specifications, featuring reinforced concrete walls and an open or partially enclosed gun position. Today, many of these bunkers remain as silent witnesses to the intense military history of the region, often explored by military history enthusiasts and urbex adventurers.
