OB 10,5cm Geschütz is a German World War II coastal artillery bunker located in Norway. This concrete fortification was part of the Atlantic Wall defensive system constructed by Nazi Germany along occupied European coastlines. The designation 'OB' indicates it was an observation bunker, while '10,5cm Geschütz' refers to the 10.5cm gun battery it was designed to support.
These bunkers formed part of Germany's extensive coastal defense network in Norway, which was strategically important for controlling sea lanes and protecting against potential Allied naval incursions during the war.
