The former headquarters of Bulgaria’s Communist Party are just as eerie on the outside as on the inside. The flying-saucer-like building, while probably a wonder while it was in use from 1981 until 1991, went into disrepair soon after the fall of the Soviet Union. It is now a ghost of its former self, although plans are being made to restore it.
Kolmanskop was a small settlement in Namibia that saw a boom in the early 1900s when German settlers realized that the area was rich in diamonds. The surge of wealth gave out after WWI, however, when the diamond field began to deplete. By the 1950s, the town was completely deserted, and is now visited by photographers and tourists.
