Johannesburg, also known as Joburg, Jozi and the City of Gold, is Africa’s economic powerhouse, driving trade and commerce across the continent. The city was founded in 1886 during the Witwatersrand gold rush, making it one of the world’s youngest major cities. Africa’s second largest metropolis (after Cairo in Egypt) is also home to the earth’s largest man-made forest, with over 10 million trees sheltering Joburg’s streets.
