The 6 Most Extravagant Underground Cities

6. Matmata, Tunisia

In the small south Tunisian Berber town Matmata, a number of the local residents live in traditional underground ‘troglodyte’ structures. These structures are created by digging a pit in ground, around the perimeter of which caves are then dug to serve as rooms. This set up is particularly useful for sheltering the villagers from the scorching heat of the sun. Some of the homes are made up of multiple pits that are then connected by passageways.
