New Delhi: Known as the Opal capital of the world, Coober Pedy is a town in South Australia.
The interesting fact about this place is people live underground.
This cavernous community was built by miners sheltering from harsh daytime temperatures, and now includes an underground church, museums, potteries, shops, an art gallery and a hotel; residents emerge at night to play golf on grassless courses using illuminated balls.
The town has a population of 3,500 and over 45 different nationalities.
