Balaklava Submarine Base, Crimea
The Balaklava Submarine Base was a Soviet submarine base that was constructed during the Cold War. It once housed the war’s most destructive weapons in its now-abandoned tunnels. The place was ditched in 1993 and can now be seen by visitors on tours of the mysterious derelict site.
Rubjerg Knude Lighthouse in Denmark
The Rubjerg Knude Lighthouse on the North Sea Coast of Denmark opened in 1900, and operated until 1968. The lighthouse was used as both a museum and a coffeeshop, but it was closed in 2002 due to rising sands. Tourists can still visit it, but the sands are expected to cover the entire structure within a few years.
