The troglodyte houses in Matmata, Tunisia are a must see if you visit the region. The troglodyte houses (a troglodyte is a person who lives in caves) are concentrated in the arid valleys of southern Tunisia, in the Djebel Dahar region of the Berber-speaking town of Matmata. The center of some pits are also reserved for a well about 20 feet deep for underground water supply. These traditional underground troglodyte structures were hidden for centuries and no one had any knowledge of their existence until 1967. Though intensive rains have flooded some houses and caused many of them to collapse, troglodyte homes in Matmata are still a popular tourist attraction.
