It is located in the Free State Province, South Africa, and named after the town of Vredefort (grey, lower centre), which is situated near its centre. It is a UNESCO World Heritage Site and measures approximately 250-300 kilometres in diameter. It is one of only a few multi-ringed impact craters on Earth and is thought to have been formed over 2 billion years ago, during the Palaeoproterozoic era.
