Chegga is an abandoned fort in the very northeastern part of Mauritania, close to the borders with Algeria and Mali.

There are neolithic rock carvings in the oued 500 meters away from the fort, near a water source.

It was built by the French Foreign Legion and taken over by the Army of Mauritania after independence.

[1]In 2019, president Mohamed Ould Ghazouani, opened the surrounding military exclusion zone to prospecting on a limited basis, although technically foreigners can still be shot on sight.

Chegga has since become a center of artisanal gold mining by Mauritanians and Malians using hand tools.
