The Tsodilo hills are a world heritage site in Botswana. These hills are famous for containing over 4500 rock paintings, some of which are about 24,000 years old. There are four hills: The Father, The mother, The Child, and an unnamed hill. Most of the paintings are found on the Mother hill. They are also sacred to the San people, who believe that the first spirit knelt on one of the hills after creating the world, and that now the spirits of their ancestors reside in the Mother hill.
