This German ghost town in Namibia was once a rich diamond mining town. It was built up with German style buildings and lots of amenities. The diamonds were exhausted by the 1950s and the town closed in 1954. "Destination Truth" did a wonderful episode on this bizarre abandoned town. No one is allowed there without permit, as it is restricted land.
This site had amazing pics of the place.
