This small inner-city park and green square behind the historic Rissik St Post Office is named after the famous South African mining tycoon. A vibrant public space, it was restored in 2010 to include a basketball court and numerous public artworks, among them the 'Oppenheimer diamond.' An impala sculpture pays homage to the original Leaping impalas at Anglo American’s headquarters nearby, that were rescued after being stolen and hacked up for scrap.
