Iranian Troglodyte Homes~The Iranian village of Kandovan is usually described as a "gigantic termite colony". Volcanic rock formed a small group of cone-like caves that eventually attracted human inhabitants. The small town, like many of the other underground dwellings on this list, has become a veritable tourist destination.

Icelandic Turf Houses For over 1,000 years, Iceland has been constructing these turf houses, which blend into the landscape and capitalize on nature's insulation. While similar constructions in Norway, Scotland, Ireland and Greenland were only built by those who couldn't afford anything else, turf houses in Iceland were even built by tribe chiefs.
French Troglodyte Homes Domesticated cave dwellings are usually called "troglodyte homes," and the Loire River Valley in France is full of them. Excessive quarrying of the local rock in the 11th century created cavities in the hills and plains, and not surprisingly, people moved in... and never moved out.
