Twyfelfontein, meaning doubtful spring, is an evocative landscape of ancient rock engravings and paintings in the Kunene Region of north-western Namibia. The valley is home to a freshwater spring which, in the times of the original San Bushman artists, drew huge numbers of wildlife to the area. The valley is surrounded by the slopes of a sandstone mountain, receives very little rainfall, and has a wide range of diurnal temperatures.

The site has been inhabited for around 6,000 years, first by hunter-gatherers and later by Khoikhoi livestock herders. Displaying one of the largest concentrations of rock petroglyphs (engravings) in Africa, UNESCO approved Twyfelfontein as Namibia’s first World Heritage Site in 2007.
