It may be lodged in Africa’s most southerly nation, but Johannesburg feels like the crossroads of a continent. This is where nationalities converge amid a buzz so vibrant that visitors immediately feel like locals. And if you want to understand Joburg, visit Soweto. Vilakazi Street was home to Nelson Mandela and Archbishop Desmond Tutu, and the former president’s former house is now a museum, a moving tribute to his life here and the icon he subsequently became. Next stop, the Apartheid Museum. So much more than a history lesson, the museum holds the key to understanding South Africa’s turbulent past. And the photographs of the 1976 Soweto uprising are as moving and powerful a social document as you’re ever likely to see.
