Ponte City

Nothing sums up the changing fortunes of inner-city Jo'burg better than Ponte City, which can be visited on tours with Dlala Nje. This 54-storey cylindrical skyscraper was hijacked in the late 1980s by squatters and rapidly declined into a vertical urban slum. Flash forward a couple of decades – the building's owner, Kempston, has taken back control and refurbished the structure, which is now safe and home to an ethnically mixed community of working- and middle-class South Africans.
