India's African roots

Is this an Aum sign with the right part obliterated by storm waters over hundreds of years?If so, who built it, and when?

Or is it part of the ruins as seen in the old kingdoms of Mapungubwe and Zimbabwe?

One view is that this "stone circle" shows clear evidence that Hindus lived and prayed in southern Africa a long time ago.

We explore the ruins and the different theories that surround them, narrating the bits we know for fact as well as rumours of aliens around the camp fire, to groups ranging from families to bus loads.
