In Saudi Arabia, the "Vault" project aims to create a vertical underground community carved into the mountains, flipping traditional urban sprawl on its head to preserve the desert surface.
This is one of the world's most famous "underground cities," a 32-kilometer maze of tunnels connecting shopping malls, hotels, and metro stations. It allows residents to navigate the downtown core without ever facing the brutal Canadian winter.
The surface might be where we show off our architecture, but the underground is where we reveal our resilience. Underground Cities
Today, underground cities are more about escaping the weather than escaping an invading army. Modern subterranean networks are booming in extreme climates.
The most iconic example of ancient underground engineering is in Turkey’s Cappadocia region . This was no mere cave; it was an 18-level deep metropolis that could house up to 20,000 people. In Saudi Arabia, the "Vault" project aims to
Whether it's the Seattle Underground (a city built on top of its own ruins) or the secret tunnels of Tokyo , these spaces challenge our two-dimensional view of geography. Living underground forces us to reconsider how we use volumetric space, how we interact with our environment, and what it truly means to be "hidden."
As surface space becomes a luxury, architects are looking at the "underground advantage" for sustainability. The surface might be where we show off
Finland’s capital is actively building "down" instead of "out" to curb urban sprawl. Their underground city includes everything from swimming pools and a hockey rink to the world’s greenest data center, cooled by the sea.
