This area of Australia is full of holes in the ground: when you'll understand why you will be shocked !

The village you see, located in South Australia, has an interesting history. In 1915, father and son came here in search of gold, but they found huge deposits of opal. This great wealth attracted dozens of people in the area, and because of sandstorms and temperatures (over 50 °) they began digging dwellings in the ground, only to create the village of Coober Pedy: here you can find cafes, libraries, churches and even hotels.
