OB 13.8cm Geschütz (f) is a German World War II coastal artillery bunker located in southern France. This fortified position was part of the Atlantic Wall defensive system constructed by Nazi Germany along the French coastline. The designation 'OB' stands for 'Objekt' (object), while 'Geschütz (f)' indicates it housed captured French artillery, specifically a 13.8cm gun.
The bunker was strategically positioned to defend the Mediterranean coast against Allied naval forces. Today, this concrete fortification stands as a historical remnant of the extensive military infrastructure built during the German occupation of France.
