Hashima Island, Nagasaki, Japan
The now-deserted Hashima Island was actually once the most densely populated island in the entire world. Its appeal was an underwater coal deposit located right under the island. However, once the coal ran out, its population began to dwindle and has since become an empty ghost town.
Teufelsberg, Berlin, Germany
Teufelsberg was once used as a listening station during the Cold War. The station lies on top of a 262 foot hill named Devil’s Mountain. It was built by the NSA in order to listen in on East Berlin, but once the Berlin Wall came down in 1989, it was abandoned. Now it is overrun and completely covered in graffiti.
