11 Diagonal Street is a striking 80-meter tall skyscraper located in the central business district of Johannesburg, South Africa. Designed by the renowned architect Helmut Jahn and completed in 1984, the building is famous for its unique shape that resembles a cut diamond.

The structure consists of 22 floors and was originally commissioned for the Anglo American Property Services. Its innovative design stood out during the 1980s as a symbol of modernism in the city's architectural profile. Today, it remains one of the most recognizable landmarks in Johannesburg due to its geometric precision and aesthetic brilliance. The building's glass facade creates a dynamic visual effect, changing its appearance throughout the day as the sunlight shifts.
