OB 60cm Scheinwerfer is a World War II-era German military bunker located in northern France. This structure was part of the Atlantic Wall fortifications built by Nazi Germany to defend occupied territories against Allied invasion. The designation 'OB' refers to 'Offene Bauart' (open construction type), while '60cm Scheinwerfer' indicates it housed a 60-centimeter searchlight for anti-aircraft defense.
The bunker's strategic position near the Belgian border made it an important component of the German defensive network in northern France.
