OB 15.5cm Geschütz is a German World War II coastal artillery bunker located in Belgium, part of the Atlantic Wall fortifications built to defend against Allied naval forces. This concrete structure housed a 15.5 cm naval gun, designed to provide long-range coastal defense along the Belgian coastline. The bunker exemplifies the standardized Regelbau designs used by the German military during the occupation of Belgium.
The site is situated in a strategic coastal location, where it formed part of a larger defensive network including other artillery positions, observation posts, and communication bunkers. These fortifications were constructed between 1942 and 1944 as part of Germany's extensive coastal defense system stretching from Norway to the Spanish border.
Today, OB 15.5cm Geschütz stands as a historical monument to the Atlantic Wall era, with its reinforced concrete structure remaining largely intact. The bunker serves as a reminder of Belgium's wartime history and the extensive military engineering projects undertaken during the German occupation.
