Matmata is a village of Berber origin. Located at the gateway to the Sahara Desert it is characterized by a unique troglodyte architecture, which has become a destination for many tourists after being set for the movie Star Wars, Episode IV - A New Hope (1977). The houses that characterize this town are dug into the ground, inside the hills and formed by an open-air courtyard, similar to a crater about 7 meters deep, which is accessed through a gallery from the hillside. From the open-air courtyard, which also has the function of collecting the rare rainwater, the various rooms of the houses are dislocated, dug like narrow tunnels on the sides of the "crater".
