Ksar of Ait Ben Haddou.

Aït Benhaddou is a historic ksar (fortified village) located on the slopes of a hill next to the Ounila River between the Sahara and Marrakesh in Morocco. The ksar's structures are made entirely out of rammed earth, adobe, clay bricks, and wood. It is considered a great example of Moroccan earthen clay architecture and has been a UNESCO World Heritage Site since 1987 Ouarzazate-Morocco.
