OB 15.5cm Geschütz (zerst.) is a destroyed German coastal artillery bunker located in Normandy, France. This type of bunker was part of the Atlantic Wall fortifications built by Nazi Germany during World War II to defend against potential Allied invasion. The designation 'OB' indicates it was an observation bunker, while '15.5cm Geschütz' refers to the 15.5cm caliber gun it once housed.
The '(zerst.)' suffix confirms the structure was destroyed, likely during the D-Day landings or subsequent Allied operations in 1944.
