The South African National Museum of Military History in Johannesburg was officially opened by Prime Minister Jan Smuts on 29 August 1947 to preserve the history of South Africa's involvement in the Second World War. In 1975, the museum was renamed from the South African National War Museum and its function changed to include all conflicts that South Africa has been involved in. In 1999 it was amalgamated with the Pretoria-based Transvaal Museum and National Cultural History Museum to form the Northern Flagship Institution. In April 2010 Ditsong was officially renamed Ditsong Museums of South Africa and the SANMMH was renamed the Ditsong National Museum of Military History.

Tswaing is an impact crater enclosed by a 1,946 ha nature reserve, situated in northern Gauteng province, South Africa. The crater and reserve are situated on a base of ancient granite of the Bushveld Igneous Complex, some 40 km to the north-northwest of Pretoria. This astrobleme is 1.13 km in diameter and 100 m deep and its age is estimated to be 220,000 ± 52,000 years (Pleistocene). The impactor is believed to have been a chondrite or stony meteorite some 30 to 50 m in diameter that was vaporised during the impact event. Morokweng impact structure, another South African crater of chondrite origin, lies north-west of Vryburg. Since 1996 it falls under the auspices of Ditsong Museums of South Africa.
