The cave homes of Matmata, Tunisia.

 
   
 
 

It is very hot in Matmâta, Tunisia. Traditionally homes are made by digging a large pit, about 7m (23ft) deep and 10m (33ft) wide, and then around the sides of the pit tunnelling in a few meters before cutting caves. The homes are grouped around a central courtyard and connected to other courtyards with more rooms forming an underground maze. You can read more about these cave homes here.
