Kolmanskop, Namibia
Kolmanskop was at its liveliest in the early 1900s, when German miners came to the area to hunt for diamonds. With them, they brought German architecture, giving the desert area an opulent, out of place look. The town featured a ballroom, a hospital, and a bowling alley among other amenities.
The town's decline began shortly after World War I, but the final nail in the coffin was the 1928 discovery of a diamond-rich area along the coast. Most of Kolmanskop's residents hurried to the new hotspot, leaving their belongings and the town behind.
Kolmanskop has been slowly getting eaten by the desert ever since. Tours to Kolmanskop can be booked in the nearby coastal town of Lüderitz.
