Nefta is a town and oasis in Tunisia, close to the Algerian border, and just north-west of the Chott el Djerid. A town of cube-shaped, flat-roofed houses huddled closely together, with Tozeur-style decoration. In some of the streets the upper stories of the houses, borne on round headed arches, project over the street, forming a kind of tunnel which offers protection from the sun.
