Here you will find significant old buildings and fascinating museums. The Transvaal Museum has natural history displays and is the home of Mrs Ples, the australopithecine fossil found at Sterkfontein in the Cradle of Humankind. Also worth visiting are the Cultural History Museum and Smuts Museum in Irene, outside Pretoria. The city centre is laid out in typical city fashion on a grid with wide roads, making getting around fairly simple.
