'Adam's Calendar' at Blaauboschkraal
Since 2003 a stone circle in Mpumalanga has been promoted as 'Adam's Calendar', supposedly a 75,000-year-old astronomical site built by the first humans or by visiting Anunnaki.

The account
The pilot Johan Heine drew attention to it, and the writer Michael Tellinger linked it to thousands of stone circles in the region, which he claims were part of an ancient gold-mining civilisation.
The sceptical view
Archaeologists identify the stone walls as homesteads and cattle enclosures of the Bokoni people, built from about the 16th century; the site was declared a monument in 1975 as such.
