Museums in region:


South Africa is a country very rich in mineral resources. The Bushveld complex is an important source of chromium and platinum. The Witwatersrand is the largest gold mining area in the world. Diamond is also an extremely important mineral to the nation.

South Africa is subdivided into nine provinces which in turn are divided into 52 districts (8 metropolitan and 44 district municipalities).
