Aït Ben Haddou is a historic ighrem or ksar (fortified village) along the former caravan route between the Sahara and Marrakesh in Morocco. It is considered a great example of Moroccan earthen clay architecture and has been a UNESCO World Heritage Site since 1987.

The ksar, a group of earthen buildings surrounded by high walls, is a traditional pre-Saharan habitat. The houses crowd together within the defensive walls, which are reinforced by corner towers. Ait-Ben-Haddou, in Ouarzazate province, is a striking example of the architecture of southern Morocco.
