Johannesburg is a city in South Africa. It is the capital of the Gauteng Province. It was founded on October 4, 1886 and has the JSE Securities Exchange, which is the largest stock exchange in Africa.
Johannesburg houses the tallest office block in Africa, the Carlton Centre (50 stories) and the tallest tower, the Hillbrow Tower (270 metres, or 90 stories). The city is nicknamed Egoli, which means "place of gold". Forty percent of the world's gold has been found here.[source?] The Johannesburg Zoo was established in 1904, and historically, it has been owned and run by the city of Johannesburg. It houses the only two polar bears in Africa. Johannesburg is not seen as a tourist centre in South Africa, but rather as a commercial centre.
Nelson Mandela died there on 5 December 2013, aged 95. He was also given the "Freedom of the City" award.
