What Iran Built Beneath the Desert

Описание: Ancient Persian engineers built underground water systems that still work today.

More than 2,500 years ago, people in what is now Iran created qanats — underground tunnels that carried groundwater across desert landscapes using nothing but gravity.

No pumps.
No electricity.
No steel.

Just precise engineering and an understanding of geology.

These gently sloped tunnels captured water in mountain aquifers and transported it for miles beneath the desert, protecting it from evaporation and delivering it directly to farms and settlements.

For centuries, #qanat systems allowed cities to survive in some of the driest environments on Earth.

But underground engineering in Iran did not stop there.

Today, the same geological environment that once supported ancient water tunnels is used for modern underground energy storage.

Engineers drill into massive salt formations and create huge caverns deep below the surface.

These #saltdome caverns store natural gas underground because salt slowly seals fractures under pressure, creating nearly airtight geological containers.

From ancient water tunnels to modern gas storage, this landscape hides remarkable systems beneath the surface.

Sometimes the most important infrastructure is the one you never see.
