Fjell Fortress, Coastal defense fortress in Sotra, Norway
The fortress contains an extensive network of underground tunnels stretching two miles through the mountains, featuring military installations and bunker systems.
German occupation forces constructed the fortress between 1942 and 1943, installing a 28 cm naval gun turret from the battleship Gneisenau for coastal defense.
Museum Vest maintains the fortress as a heritage site, presenting exhibitions about Norwegian coastal defense and military operations during World War II.
The fortress welcomes visitors from Tuesday to Sunday between 11:00 AM and 4:00 PM, offering guided tours and a cafe in the former gun emplacement.
Twenty-five eastern European prisoners lost their lives during the construction of this fortress, which required digging 17 meters vertically into the mountain.
