TOMBS - OLDER THAN
Stone circles like those in the Djibouti and Eritrea area abound throughout North Africa. They can be found all over the Sahara, from the Atlantic coast in Mauritania to Saudi Arabia and Jordan. At their centre is a small round chamber called a tumulus, which was usually used to bury the deceased. They come in all imaginable sizes. The largest stone circle I have found so far measures a proud 150 metres in diameter. If this really was the site of the legendary gold country of Punt, from which the ancient Egyptians had been importing goods since at least 3,000 BC, then these structures could be considerably older than 5,000 years.
