Top of Africa (Carlton Centre)

The Carlton Centre is a 50-storey skyscraper and shopping centre located on Commissioner Street in central Johannesburg, South Africa. At 223 metres, it was the tallest building in Africa for 46 years from its completion in 1973 until 2019. It is today the continent's fifth tallest building after The Leonardo, the Mohammed VI Tower in Morocco, the Great Mosque of Algiers Tower in Algeria and the Iconic Tower in Egypt. The foundations of the two buildings in the complex are 5 m in diameter and extend 15 m down to the bedrock, 35 m below street level. The building houses both offices and shops, and has over 46 per cent of the floor area below ground level.

The Carlton Centre is linked to the Carlton Hotel by a below-ground shopping centre with over 180 shops.
