Kolmanskop, Namibia Formerly a bustling diamond mining town, after the market declined, inhabitants began leaving the town after WWI; by 1954, it was completely deserted. As it was an enclave for German colonialists for many years, the architecture is not only out of place, but its abandonment enhances it even more.
Island Hashima (Ghost Island), Japan Abandoned since 1974, Mitsubishi built this remote island around a large coal deposit, where is housed 5,000 residents. Today it has a post-apocalyptic atmosphere, and tourists are free to roam this empty ghost town. COOL!
