Aït Benhaddou, Morocco's Clay Fortress

Aït Benhaddou has been a UNESCO World Heritage Site since 1987.

The ksar is a fortified village along the Ounila River in Morocco.

Camels once walked this route between the Sahara and Marrakesh.

The site of the ksar has been fortified since the 11th century.

Builders used rammed earth for the first floor. Mud works.

Upper floors were built with lighter adobe to reduce wall load.

Earth mixed with straw erodes easily when exposed to rain over time.

Buildings are grouped together within a defensive wall featuring corner towers.

Some upper walls are decorated with geometric motifs.

At the top of the hill stand remains of a large granary.

Most inhabitants now live in modern dwellings across the river.

A new pedestrian bridge was completed linking both sides in 2011.

Hollywood films and Game of Thrones used Aït Benhaddou as a location.

Restorations keep Aït Benhaddou standing using traditional materials and techniques.
