Situated in the far north of the Free State, Sasolburg is one of the most important industrial areas in South Africa.
Sasolburg was initially established to provide housing and facilities for the employees of Sasol in 1954. Today many of the residents of Sasolburg still choose the town because of the proximity to Sasol.
Sasolburg is at a high altitude with a fairly dry climate and large seasonal temperature variation. It is situated near the Vaal river, which separates the Free State from what was formerly the province of Transvaal, and is not far from the Vaal dam where excellent windsurfing spots can be found.
The Sasol corporation has sponsored extensive infrastructural developments in Sasolburg, such as an Olympic size swimming pool. World class athletics facilities and a large number of churches can also be found in Sasolburg. The Ettienne Rousseau Theatre plays host to a wide range of Afrikaans and other artists throughout the year. It is served by Sasolburg High School.
