Matmata or Metmata is a small Berber speaking town in southern Tunisia. Some of the local Berber residents live in traditional underground "troglodyte" structures.
The structures typical for the village are created by digging a large pit in the ground. Around the perimeter of this pit artificial caves are then dug to be used as rooms, with some homes comprising multiple pits, connected by trench-like passageways.
The hotel Sidi Driss served as the home of Luke Skywalker on the planet Tatooine in the Star Wars movies. Episodes II, III and IV.
