On the southern tip of the island of Amager is a derelict and seemingly abandoned bunch of concrete buildings and earthen ramparts. This is the Kongelundsfort or Fort Kongelund, a part of the fortifications of Copenhagen that has been abolished for many years. This fort was built as a coastal battery to protect the minefields that would have been laid in the Bay of Køge in the event of war.
It was built in 1914 - 1916 and converted in 1959 to a radar station for the NIKE missile batteries that would have protected Copenhagen from aerial attack during the Cold War. In 1982 it was abandoned by the military and later turned over to Dragør Municipality. The barracks are used for asylum seekers and the rest of the fort is open to the public. I'll show some more photos of this fort tomorrow.
