Ksar D'Aït Benhaddou (Berber: Ath Benhadu‎) is a "fortified city", or "Ksar", along the former caravan route between the Sahara and Marrakesh in present-day Morocco. It is situated in Souss-Massa-Dray on a hill along the Ouarzazate River and has some beautiful examples of Kasbahs, which unfortunately sustain damages during each rainstorm. Most of the town's inhabitants now live in a more modern village at the other side of the river; however, ten families still live within the Ksar.
Ksar D'Aït Benhaddou has been a UNESCO World Heritage Site since 1987.
