GENERAL INFORMATION ON HARRISMITH

Harrismith is a large town in the Free State province of South Africa. It was named after Sir Harry Smith, a 19th century British governor of the Cape Colony. It is situated by the Wilge River, alongside the N3 highway, about midway between Johannesburg, about 300 km to the north-west, and Durban to the southeast. The town is located at the junction of the N5 highway, which continues westward towards the provincial capital Bloemfontein, some 340 km to the south-west. This important crossroads in South Africa's land trade routes is surrounded by mesas and buttes. It is located at the base of one of these called Platberg (i.e. "flat/flat-topped mountain" in Afrikaans).  Coordinates: 28o17’00”S 29o08’00’’E / 28o17.0’S 29o08.0’E
