During the Cold War, the allies used Teufelsberg in Berlin as a spy station to listen in on the Soviet forces. Nowadays it’s in a state of disrepair having been abandoned by the allies at the fall of the Berlin wall, and the unification of west and east Germany.
Since then it has been in the hands of various private owners but nothing has been developed. It’s left relatively untouched, apart from the graffiti artists that is.
Graffiti artists from all over the world come to do their work there, and it usually only lasts a few days before the next artist paints over it.
