There is a town located in the Australian Outback just north of Adelaide called Coober Pedy and it is completely underground. The town was named Coober Pedy after the word "Kupa-Piti," an Aboriginal word that means “white man’s hole."
In 1915 people discovered a rich deposit of opal in the area and the workers needed somewhere to live. The area was too hot to live comfortably in the summer months, so instead of finding another town to live in they built a town underground that would stay cool in the summer and warm in the winter.
The more “dugouts” that were built, the more the town grew over the years. There are currently 3,500 residents in Coober Pedy and almost all of them live underground. Temperatures outside of the “dugouts” reach up to 115 degrees Fahrenheit in the summer, so if you live there, you’d want to live down under.
If you’ve seenMad Max Beyond Thunderdome, than you’ve already seen Coober Pedy. In 1985 Mel Gibson, Tina Turner and the rest of the cast and crew used the town as the backdrop for the post-apocalyptic movie.
It sounds like a claustrophobic nightmare, but Robert Coro, the managing director of the Desert Cave Hotel explains why people would want to live there.
“The beauty of living underground is that it’s very quiet and very still...There’s no air movement or rush of air from the air conditioner, and since there are no windows or natural light, you get a very peaceful night’s sleep.”
