That isn't a city it's a geological formation caused by erosion at different rates in different rock types.
It is known as the Richat Structure
https://en.wikipedia.org/wiki/Richat_Structure
If you zoom in to the highest resolution you will see there are no walls at all, this was never a city.
Initially interpreted as an asteroid impact structure because of its high degree of circularity, the Richat Structure is now regarded by geologists as a highly symmetrical and deeply eroded geologic dome. After extensive field and laboratory studies, no credible evidence has been found for shock metamorphism or any type of deformation indicative of a hypervelocity extraterrestrial impact.
I found walls, and ruins...
I read they found salt, but I need more information. I think multiple events have shaped that site. First, there are others, and some look like they too have been utilized for human activity.
Look at the sand that was carried through the pillars...! The wash of sand looks over 300 miles wide!
when was Africa last flooded?
