'Star Wars:' Matmata Underground Houses - C104, Matmatat-Al-Qadimal, Tunisia

The underground homes of Matmata were built by the Berbers as a cool place to live in the parched desert region. The troglodyte homes were perfect as a film set for the “Star Wars” films. However, as many of the Berber people are now leaving the area, the underground homes may be destroyed by extreme drought or flooding, with no one around to fix them.
