OB 17cm Geschütz (zerstört) is a German World War II coastal artillery bunker located in northern France. This destroyed gun emplacement was part of the Atlantic Wall fortifications built by Nazi Germany to defend against Allied invasion. The designation 'OB' indicates it was an observation bunker, while 'Geschütz' refers to its artillery function.
The '(zerstört)' suffix confirms the structure was destroyed, likely during Allied bombing campaigns or ground operations in 1944. Located near the coast, this bunker would have housed a 17cm caliber gun as part of Germany's defensive network along the French coastline.
