Underground city in Australia

There is in Australia, an interesting town, situated between Adelaide and Alice Springs, called Coober Pedy. Name of Coober Pedy is translated from the language of Australian aborigines, as a “white man’s burrow” or “white man under the ground.” He is known not only for being the world capital of precious opal, but its only the world’s underground city and Cave Hotel Desert Cave.
Underground is a whole city. It was built miners to their families at the beginning of last century. In Coober Pedy is very hot, and under the earth, even in summer the temperature reaches a maximum of 26 degrees. About a depth of 6 meters is cool as lying above the rock absorbs the heat of the desert sun. Even the first prospectors realized that you can relatively comfortably under the ground, in housing that is almost worthless. That until their successors are elected, they and their families are living in today’s underground comfort. Many of their houses are very large and simply luxurious, and some have even underground pools, while very close, on the surface, the sun beats down mercilessly ground.
