Did you know… there is a city built entirely underground?
When we imagine a city, we picture buildings, streets, squares, and monuments spreading across the surface. Yet, in the heart of the Australian desert, there is a place that completely flips this idea: a city built almost entirely underground, where living below the surface has become the norm.
Coober Pedy: the invisible city in the desert
Coober Pedy is located in South Australia, hundreds of kilometers from major urban centers. From above, it looks almost alien: red earth, very few buildings, and thousands of holes scattered across the landscape. But it is beneath those holes that the real city is hidden.
The name Coober Pedy comes from an Aboriginal expression meaning “white man’s hole”, referring directly to how the first inhabitants dug shelters into the ground to survive.
Why live underground?
Summer temperatures in Coober Pedy can easily exceed 45°C (113°F), making life on the surface almost impossible for long periods. Living underground, however, maintains a stable temperature of around 22–24°C (72–75°F), without the need for artificial cooling systems.
This natural solution has made underground homes not only more comfortable but also energy-efficient, well-insulated from noise, and protected from sandstorms.
A real city… beneath the surface
Coober Pedy is not just a collection of rock-cut houses. Underground, you can find:
- fully equipped homes
- underground churches, such as the famous Serbian Orthodox church
- hotels carved into the rock
- shops and art galleries
- restaurants and bars
Much of the social life takes place below ground, creating a unique and surprisingly welcoming environment.
Opal: the wealth that gave rise to the city
The origin of Coober Pedy is closely tied to the discovery of opal in the early 1900s. Thousands of prospectors came from all over the world in search of fortune, digging tunnels into the ground. Many of these tunnels, once mining activity ended, were transformed into homes.
Even today, opal remains the city’s economic heart and has earned Coober Pedy the nickname “the opal capital of the world.”
A place out of time (and the world)
Coober Pedy feels suspended in another dimension. The silence of the desert, the cool underground air, and the lunar-like surface create an almost surreal atmosphere. Unsurprisingly, the city has been chosen as a filming location for numerous science fiction movies.
Here, the concept of a city merges with survival, ingenuity, and human adaptation.
A lesson in architecture and resilience
Coober Pedy is much more than a geographical curiosity: it is a concrete example of how humans can adapt to their environment without fighting it, using simple but effective solutions.
In an era increasingly focused on sustainability, this underground city demonstrates that sometimes the best answers are already beneath our feet.
