Ponte City is a skyscraper in the Hillbrow neighborhood of Johannesburg, South Africa. It was built in 1975 to a height of 173 m (567.6 ft), making it the tallest residential skyscraper in Africa. The 54-story building is cylindrical, with an open center allowing additional light into the apartments. The center space is known as “the core” and rises above an uneven rock floor. Ponte City was an extremely desirable address for its views over all of Johannesburg and its surroundings. During the late 80s gang activity had caused the crime rate to soar at the tower and the surrounding neighborhood. By the 1990s, after the end of apartheid, many gangs moved into the building and it became extremely unsafe. Ponte City became symbolic of the crime and urban decay gripping the once cosmopolitan Hillbrow neighborhood. The core filled with debris five stories high as the owners left the building to decay.
