The San, direct descendants of Stone Age inhabitants, have a legacy spanning many centuries across large parts of southern and eastern Africa. Rock art dating back thousands of years in some cases stand testament to the very enduring power of the San people. Not only is their presence of immense historical importance to Namibia's ancient cultural heritage, but to its present heritage, too. Namibia's Khoisan population is the largest in Africa and largely concentrated around the northern The Kalahari.
