Namibia’s first World Heritage Site is a huge open-air gallery of more than 2000 rock engravings. Twyfelfontein is home to one of Africa’s largest and most important collections of rock art. The engravings are attributed to San shamans who prepared themselves for a trancelike state by working these images into the sandstone. The images themselves are mostly collages of animals that represent the shaman’s visions during his trance. Most of the engravings are estimated to be about 6000 years old. Twyfelfontein was proclaimed a National Monument in 1952 and was declared a UNESCO World Heritage Site in 2007. Twyfelfontein lies in the rocky Huab Valley that is dominated by red sandstone formations. The site got its name doubtful fountain from a farmer who settled in this area and was unsure whether the nearby spring would provide enough water. A visitor’s centre and pathways have now been created on the site to guide visitors through this ancient art exhibition.
