Since 1973 the Carlton Centre has been the tallest skyscraper on the continent. At 223 metres, it deserves to be known as the Top of Africa. The building houses both offices and shops, and has over 46% of its floor area below ground level. The Carlton Centre was designed by the American architectural firm Skidmore, Owings and Merrill and cost over R88 million to build. Head to the observation deck and enjoy a panoramic view of the City of Gold.
