Twyfelfontain is Namibia's first UNESCO World Heritage Site for its over 2,500 pictographs, produced by the Khoikhoi peoples in the sandstone. The oldest might be as old as 10,000 years and probably ended around 1000 A.D. Some, like this flamingo, aren't even found in the area, and indicate that there might have been contact with the coast, 100 km. west of here.
