Johannesburg , Africa’s largest city, is a sprawling metropolis that can be impressively viewed from the observatory deck of the Carlton Centre. It is also home to Soweto, a township that has become a byword for the crimes of the defeated Apartheid system. The Museum Africa details local history. Johannesburg also has one of South Africa’s most important stages, the Market Theatre. The UNESCO World Heritage Site Cradle of Humankind, an area rich in fossil hominid finds, is located about 30 km outside the city.
