This site is located in the northwestern part of the Central Free State, South Africa, approximately 120 km southwest of Johannesburg, and it covers a core protection area of 300 km2. The heritage site includes a large part of a meteorite impact structure that dates to 2.023 billion years ago. It is the oldest impact crater to be discovered on the Earth’s surface. With a radius of 190 km, it is the largest and most heavily eroded impact crater. The Vredefort Crater witnessed the largest single energy release event on Earth and provides a complete subsurface geological profile of an impact crater.
