A military bunker located near Kristiansand, Norway, situated in a commanding position above the Skagerrak Straits between Norway and Denmark. This historic fortification once housed the second largest cannon in the world - a Krupp 380mm artillery piece with a range of up to 55 kilometers and weighing 337 tonnes. Originally constructed during World War II by German forces, the bunker represents Norway's complex military history spanning from the Nazi occupation through the Cold War period.
The site exemplifies the strategic importance of Norway's coastal defenses and has been closed to the public due to preservation concerns.
