The underground opal town of the Australian outback
An opal-mining town in the arid heart of South Australia where residents escape blistering desert heat by living underground in 'dugout' homes carved into the sandstone hills — complete with subterranean churches, hotels and shops. The name comes from an Aboriginal phrase often rendered as 'white man's hole in the ground.'
Opal was discovered here in 1915, sparking a rush that drew miners from around the world. To cope with summer temperatures that regularly top 40°C, they adapted the practice of digging homes into the earth, where temperatures stay comfortable year-round.
