OB 15,5cm Geschütz is a German World War II coastal artillery bunker located in northern Norway. This concrete fortification was part of the Atlantic Wall defensive system constructed by Nazi Germany along occupied European coastlines. The site features a 15.5cm gun emplacement designed to defend against Allied naval forces in the Norwegian Sea.
Like many Atlantic Wall installations in Norway, it represents the extensive German military presence in the country during the 1940-1945 occupation period.
