Located in the north of Greater Johannesburg, Sandton is an upscale commercial and residential district formed by the merging of Sandown and Bryanston. But now Sandton is home to the post-apartheid black professional class. The city's bustling business district is often referred to as Africa's richest square mile, and at its heart is Nelson Mandela Square and Sandton City, an upscale shopping mecca containing over 300 of the world's most coveted retail brands.
