TwyfelfonteinTwyfelfontein lies about 90 kilometres west of Khorixas in Damaraland. The site contains one of the most extensive galleries of rock engravings in the world. More than 2000 petroglyphes have been counted here. The rock engravings are found on a number of smooth rock surfaces and most of them depict both, wild and domesticated animals and their tracks. The engravings, attributed to the San Bushmen, are well preserved and clearly recognisable. Scientists estimate their ages to vary between 2000 and 10000 years.
In 1952, the valley of Twyfelfontein was proclaimed a National Monument. Die UNESCO awarded it in 2007 the status of a World Heritage Cultural Site. A circular trail leads visitors to the eight most beautiful stone slabs.
