Aït Benhaddou, Morocco

Aït Benhaddou (Berber: Ath Benhadu‎) is a fortified city, or ksar, along the former caravan route between the Sahara and Marrakech in present-day Morocco. Most citizens living in the area now live in more modern dwellings in a nearby village, although there are 4 families still living in the ancient city. This giant fortification, which is made up of six Kasbahs and nearly fifty ksars which are individual Kasbahs, is a great example of earthen clay architecture, which is also used in Moroccan architecture.
Aït Benhaddou has been a UNESCO World Heritage Site since 1987
