OB 15,5cm Geschütz is a German World War II coastal artillery bunker located in France. This fortified position was part of the Atlantic Wall defenses constructed by Nazi Germany along the French coastline. The bunker housed a 15.5 cm gun battery, designed to defend against Allied naval forces and protect the occupied French coast from potential invasion.
Such installations were strategically placed to control key maritime approaches and provide long-range artillery coverage of the English Channel and Atlantic waters.
