Why Do Entire Communities in Tunisia Still Live Underground? The Hidden World Beneath the Desert

From above, southern Tunisia looks like a landscape that should not contain a city at all.

The desert stretches endlessly.

Then enormous circular pits begin appearing across the earth.

At first, they look almost like scars left by something from above.

But smoke rises from inside them.

And beneath those barren surfaces, entire homes are hidden several metres underground.

For centuries, people here have carved their homes directly into the earth.

Not because they were simply hiding from the desert.

Because the desert itself offered a remarkably effective place to live.

The deeper you go, the stranger the architecture becomes.

Cool rooms, sheltered courtyards and interconnected passages form a hidden world almost invisible from the surface.

So why did entire communities choose to build their lives beneath the ground—and why do some people still remain there?

The video below takes you beneath southern Tunisia, revealing the remarkable homes, ancient adaptation and hidden history behind this extraordinary way of life.

Why Entire Communities Went Underground in Tunisia

The answer begins with the environment.

Southern Tunisia can be brutally hot, dry and exposed.

Traditional builders found a solution by going down rather than up.

A large circular pit became the centre of the home.

Rooms were then carved directly into its surrounding walls.

Bedrooms.

Storage areas.

Kitchens.

Even spaces for animals could fit within the underground layout.

The earth became the structure.

It also became the insulation.

Several metres of ground helped protect the interior from extreme temperatures outside.

Meanwhile, the open courtyard allowed sunlight and air to reach the homes below.

It was an ingenious form of climate adaptation created without modern technology.

And the design offered another advantage.

From the surface, much of the living space could remain almost invisible.

The Hidden Engineering Behind Tunisia’s Homes

The remarkable thing about these homes is their apparent simplicity.

There are no towering buildings.

No elaborate foundations.

The earth does most of the work.

The courtyard is excavated first.

Then rooms are cut horizontally into the surrounding ground.

Passages connect different parts of the dwelling, creating a surprisingly complex underground layout.

The result is architecture shaped almost entirely by the landscape.

But this ancient way of life has faced major changes.

Modern roads, electricity, new housing and economic opportunities have encouraged many residents to move above ground.

Then came another challenge.

In 1969, severe rainfall caused flooding and damage in Matmata, contributing to the development of a new above-ground settlement.

Yet many of the old dwellings survived.

Some remain homes.

Others have become reminders of a disappearing tradition.

And that creates a very different threat.

The underground world is not being destroyed by the desert.

It is slowly being left behind.

Final Verdict: Tunisia’s Hidden Underground Legacy

The underground settlements of southern Tunisia are more than unusual homes.

They are evidence of generations adapting intelligently to an extreme environment.

The underground homes transformed the earth itself into shelter.

The deep courtyards brought light and air below the surface.

And the surrounding ground helped moderate the temperature naturally.

What looks primitive from above was actually highly practical architecture.

The story of Matmata therefore reaches beyond one remarkable town.

It shows how traditional knowledge can solve problems that modern technology often approaches in completely different ways.

But the knowledge behind these homes is becoming harder to preserve.

As more families move above ground, fewer people continue the old way of living.

The greatest danger may therefore be time itself.

An architectural tradition that survived for generations could eventually become something people only visit.

Yet its lesson remains.

These communities did not defeat the desert.

They learned how to live with it.

And sometimes, the smartest place to build a home is not above the earth—but inside it.
