Qal’at Bani Hammad, also known as the Qal’a of Beni Hammad, is a notable archaeological site located in Algeria. This fortified palatine city, now in ruins, was established in the 11th century AD and served as the inaugural capital of the Hammadid dynasty. Positioned in the Hodna Mountains northeast of M’Sila, at an elevation of 1,418 meters, the site benefits from the abundant water supply from the surrounding mountains. It is situated near the town of Maadid, approximately 225 kilometers southeast of Algiers, in the Maghreb region.
