Movik Fort is a historic German coastal fortification located near Mandal, Norway, overlooking the Skagerrak Straits. Built during World War II by German occupying forces, the fort once housed the second-largest cannon in the world—a massive Krupp 380mm gun with a range of up to 55 kilometers (35 miles) and weighing 337 tonnes. The fortification sits in a commanding position above the sea, serving as a key defensive installation during the war.
After the conflict, the site was repurposed for civilian use, including as a primitive bomb shelter. Norway's Cold War military heritage includes many such bunkers, reflecting the country's strategic importance during the tense period with the Soviet Union.
