Matmata has one of Tunisia’s most unusual village landscapes. It’s a place of underground homes burrowed into the rock. At this place the Berber people dig their homes out of the ground for more than 1000 years. There are more than 100 underground houses, there is even a subterranean hotel now. The houses are built around artificial craters, 5 to 10 m deep, with doors and windows in the steep walls towards the crater. Those craters look like a patio or a Roman atrium, and the lower part of the walls is often painted white. Sometimes several of those craters are connected by a labyrinth of tunnels.
