Wall ruins 16 km northeast from Ouadane
Does anyone know what are those ruins? They look like city wall in triangle shape with side of 4 km measuring 13 km in total. It is next to Richat structure. I spoted it on Google maps, if you display oldest google map of the location with Google earth pro, the wall is not visible but there is another rectangle of 1.3 km size to be seen inside. Are there any records of what it is? City? Gardens? There is vegetation growing there in the southest part of it to these days. I would provided YouTube video of it but i cant link it here. --46.135.45.17 (talk) 17:15, 10 September 2019 (UTC)
