OB 10cm Geschütz is a German World War II coastal artillery bunker located near Wimereux, France. This defensive structure was part of the Atlantic Wall fortifications built by Nazi Germany to defend the French coastline against Allied invasion. The bunker housed a 10cm gun emplacement, designed to provide long-range coastal defense and support for nearby defensive positions.
Its strategic location along the English Channel made it a key component in Germany's coastal defense network during the war.
