Aïn Séfra
Aïn Sefra lies among the Ksour Mountains, between Jebel Aïssa and Jebel Mekter, at the edge of the Sahara. A spring and gardens sustained the old ksar beneath a long ridge of sand. According to local oral tradition, the children of Mohamed Benchaïb, known as Bou Dekhil, founded the fortified settlement around 1586 after acquiring the land from neighbouring tribes for a thousand sheep.
