The site has been inhabited for 6,000 years, first by hunter-gatherers and later by Khoikhoi herders. Both ethnic groups used it as a place of worship and a site to conduct shamanist rituals. In the process of these rituals at least 2,500 items of rock carvings have been created, as well as a few rock paintings. Displaying one of the largest concentrations of rock petroglyphs in Africa, UNESCO approved Twyfelfontein as Namibia's first World Heritage Site in 2007.
