Bou Saâda
Bou Saâda is an oasis at the southwestern edge of the Hodna, where the high plateau approaches the Ouled Naïl mountains. Springs and the waters of the Oued Bou Saâda sustain its palm groves amid the dry surroundings. The old ksar grew around a mosque, and the oasis became a meeting place on routes between the Tell, the Zab and the M'zab. Local tradition associates its founding with two holy men, Sidi Thameur and Sidi Slimane.
