When historians first stumbled upon these structures they simply assumed that they were cattle kraal left behind by the Bantu people as they moved south and settled the land from around the 13th century. But research work done by people like Cyril Hromnik, Richard Wade, Johan Heine and a handful of others over the past twenty years, into ancient southern African history, has revealed that these stone structures are in fact more than just cattle kraal, but the remains of ancient temples and astronomical observatories of lost ancient civilisations that stretch back for thousands of years.
