OB 15cm Geschütz mit Haube is a German World War II artillery bunker located in France. This type of bunker was part of the Atlantic Wall fortifications built by Nazi Germany along the coast of occupied France to defend against Allied invasion. The designation 'OB' refers to an 'Offene Bauweise' (open construction) bunker, while '15cm Geschütz mit Haube' indicates it housed a 15cm gun with a protective hood or shield.
These bunkers were typically positioned to provide coastal defense and anti-ship artillery support.
