Johannesburg has most of Africa's tallest buildings, and the building that's held the title of Africa's tallest office building for nearly four decades is the Carlton Centre.
The Carlton Centre is a combination office building and shopping center. The 50-storey building stands at 732 feet, but almost half of its floor area is below the ground level – that's where the majority of the shopping is located, in an underground shopping mall that's one of the city's top shopping destinations. Until 1997, the Carlton Centre was connected via this underground mall to the luxury Carlton Hotel.
The top floor of the Carlton Centre is known as the “Top of Africa,” and offers some of the best views overlooking Johannesburg.
