Behind the almost unpronounceable name of Twyfelfontein lies one of the greatest archaeological treasures in Namibia, if not in the whole of Africa. We are referring to a huge concentration of petroglyphs dating from around 2,000 to 6,000 years ago. Although Namibia is primarily known for its wildlife and nature, it can also offer a more cultural visit. Such is its importance that Twyfelfontein was declared a World Heritage Site by UNESCO in 2007. It is a valley inhabited for around 6,000 years by groups of Stone Age hunter-gatherers. It was these early inhabitants who are believed to have made most of the rock carvings and paintings on the site.
