Ksar Ait Ben Haddou is an ighrem (fortified village in English) along the former caravan route between the Sahara and Marrakech in present-day Morocco. Most citizens attracted by the tourist trade live in more modern dwellings in a village on the other side of the river, although there are four families still living in the ancient village. Inside the walls of the ksar are half a dozen kasbahs, or merchants' houses. Ksar Aït Benhaddou is a great example of Moroccan earthen clay architecture and has been a UNESCO World Heritage Site since 1987
