At the very center of the Richat Structure there are a semicircle of buildings or structures. You can see there are wheel tracks that lead to that area. Must be the spot where there is a fresh water well.
Also, the mysterious Chinguetti meteorite came from around that area as well.

Ouadane, Mauritania being the closest town just outside the Richat Structure (Eye of the Sahara).
