The Carlton Centre is a 732 ft or 223 meter tall building in Johannesburg, South Africa. It has been the reigning champion of tallest buildings in Africa for 39 years to this point.
It was the tallest building in the world for 25 years until the Petronas Towers in Kuala Lampur, Malaysia took this honor. The Willis Tower still holds the title as the tallest building in the Western Hemisphere, though, and itâs the seventh tallest building in the world. It holds more than 3.8 million square feet of office space. Don't miss one of the highlights of the Skydeck, the glass ledge which juts out from the side of the building.
