The well-known fact that the north of Africa in the past was a flourishing land with deep rivers has long been proven and recognized by scientists. And there are much more traces of highly developed civilizations in this region than is commonly believed.
By looking closely at aerial photographs and even using satellite imagery, it is possible to clearly distinguish dams on the beds of long-dry rivers. So, for example, studying the area near the popular resort complex Marsa Alame, you can notice an incredible object for these places, namely a two-hundred-meter platinum.
And she is far from the only one, there are simply many of them. If you study the map in detail, you can see the channels of streams and lakes, which are now without water, but are still perfectly visible. In addition, if you deviate slightly from the tourist routes, you can find the remains of clay houses, which clearly follow the contours of the channels of ancient water flows.

Unfortunately, there is simply no information about who and when built these structures. But the very presence of dams speaks volumes. After all, their existence means that the builders had a very high level of technological development, which allowed them to use the power of water for their own purposes.
