Johannesburg, South Africa's biggest city and capital of Gauteng province, began as a 19th-century gold-mining settlement after gold was found on a farm in 1884. Its sprawling Soweto township was once home to Nelson Mandela and Desmond Tutu. Mandela’s former residence is now the Mandela House museum. Other Soweto museums that recount the struggle to end segregation include the somber Apartheid Museum and Constitution Hill, a former prison complex.
Johannesburg, in 2007, boasted a population of 4.435 Million residents.
