There are few better Danish examples of Cold War paranoia than unique Langelandsfort, built in 1952-53 to defend the western Baltic against the Russians. You can descend into various bunkers and command centres, board a claustrophobic U-boat, explore a minesweeper and peer inside two fighter planes. The solid grey masses of concrete, rusting barbed wire and camouflage-green emplacements and anti-aircraft guns are in startling contrast to the picnic-perfect countryside in which they are set.
The site is big (to see everything involves a walk of about 2km) and you’ll need a couple of hours to look around. A new exhibition covers espionage during the era. The fort is just north of Bagenkop.
