Some ghost towns remain frozen in time. Some rot unappealingly. Kolmanskop, in Namibia, on the other hand, is being spectacularly consumed by desert dunes, one grain of sand at a time. Built as Consolidated Diamond Mines’ headquarters in the early 1900s, it had a bowling alley, theatre and casino. However, after richer pickings were found at Oranjemund, Kolmanskop’s time was up – it was completely abandoned by 1956. Kolmanskop is a 15-minute drive from Lüderitz, just off the B4.
