Stabben Fort is a war memorial and a solid edifice at Titran on Freya. The building was erected during the war of 150 Russian and Serbian prisoners of war. The plant was started in spring 1941 and has several underground bunkers. A hundred Germans came to Titran during the war and Stabben fort was one of many similar buildings that were built to attack Allied ships. The point of the fort was to use guns to shoot at ships, but the gun was during the war years used only once and it was due to a misunderstanding.
