About Blaauwboschkraal Stone Ruins
The Blaauwboschkraal Stone Ruins are a significant provincial heritage site located in the Mpumalanga Highlands of South Africa, approximately 10 kilometres from the town of Emgwenya (formerly Waterval Boven). Declared a national monument in 1975, the site features a series of circular stone structures and terraces that offer a glimpse into the region's pre-colonial architectural history. Structure Layout: The site includes three distinct circular stone structures. The largest circle is roughly 40 metres in diameter and contains two smaller inner circles, creating a "sacred" or highly organised enclosure. Adam’s Calendar: A specific part of these ruins is popularly known as Adam’s Calendar (or Inzalo Yelanga). Some alternative theories suggest this portion served as an ancient astronomical observatory or sun calendar, with some claims even dating it back 75,000 years, though these remain controversial among mainstream historians.
