OB 10.5cm Geschütz is a German World War II coastal artillery bunker located in Norway. This type of bunker was part of the Atlantic Wall fortifications built by Nazi Germany along occupied European coastlines. The designation 'OB' stands for 'Offene Bauweise' (open construction), indicating this was likely an open gun emplacement rather than a fully enclosed casemate.
These 10.5cm gun positions were designed to defend against naval threats and provide coastal defense for strategic Norwegian locations during the German occupation.
