Sandton is an affluent area situated in the Johannesburg Municipality, Gauteng, South Africa. The name comes from the combination of two of its suburbs, Sandown and Bryanston. Archaeological findings suggest the area, which Sandton comprises today, had originally been occupied by various indigenous groups, before European settlement, most notably the Tswana and, to a lesser extent, Sotho people. Urban decay in downtown Johannesburg caused many corporate offices to move from the Johannesburg Central Business District to Sandton in the 1990s. It has become the new financial district of South Africa and Johannesburg's premier business centre. One of the main attractions in Sandton is Sandton City, which ranks among the largest shopping centres in Africa.
