OB 10,5cm Geschütz is a World War II-era German coastal artillery bunker located in Norway. This type of bunker was part of the Atlantic Wall fortifications built by Nazi Germany along the Norwegian coast to defend against Allied naval forces. The designation 'OB' stands for 'Objekt' (object), and '10,5cm Geschütz' indicates it housed a 10.5 cm artillery gun.
These bunkers were strategically positioned to control key maritime approaches and protect German-occupied territories from naval incursions.
