In Aldar province, central Algeria, large areas of a desert seem to be covered with a regular geometric line pattern, like a rectangular grid rotated by 45 deg. Lines are mostly worn and hard to spot on satellite images but the design can be easily recognized in several locations.

I'm also attaching some screenshots.
Note the size of the pattern: each cell is ~400m high/wide. Also, the design seems pretty intricate, decorative even, with lines being subtly curved. It reminds me of Arabic style. Given the size, it looks quite impressive and may point to an advanced civilization having once lived in that region.
What are these lines and how old are they? Are they traces of an ancient irrigation grid for some cultivation areas or gardens? As we now know, western Sahara wasn't always a desert:

If the river map is accurate, the proposed Tamanrasett river reached the exact location of the patterns with its upper arm.
