There is an ancient world hidden beneath the streets of Ibiza Town, and some of its most remarkable secrets are underground.

At Puig des Molins, just beside the historic centre of Eivissa, thousands of years of burial history have survived beneath the hillside. The site is one of the most important archaeological areas on the island and offers an extraordinary glimpse into the people who lived in ancient Ibiza.

It is also one of the best places to understand just how old the story of Ibiza really is.

An Ancient Cemetery Beside the City

The Puig des Molins Necropolis developed close to the ancient settlement of Ibossim, the city established by the Phoenicians around the 7th century BC.

Its location was practical. The burial area was positioned outside the main settlement, following ancient traditions concerning the separation of the living city from the world of the dead.

Over many centuries, the cemetery expanded.

Generations of people were buried here, leaving behind an archaeological record that provides an unusually detailed picture of ancient Ibiza.

What Is a Hypogeum?

One of the most fascinating features of Puig des Molins is its underground burial chambers.

These chambers are known as hypogea, a term used for structures built partly or entirely below ground.

Many were carved directly into the rock beneath the hillside.

From above, there may be little indication that anything is there. Below the surface, however, some chambers contain passages and burial spaces that were used by ancient communities.

The result is a hidden landscape beneath the modern one.

The Tombs Were Used Again and Again

Ancient burial practices were very different from those of today.

Some of the underground chambers at Puig des Molins were reused over long periods. New burials could take place within existing tombs, creating layers of archaeological evidence.

This makes the site particularly valuable to researchers.

Instead of providing information about just one individual or one moment in time, the necropolis can reveal changes in customs and society across generations.

The cemetery effectively became an archive of ancient Ibiza.

What Did People Leave Behind?

The objects discovered in the tombs are among the most interesting aspects of the site.

Archaeologists have found pottery, jewellery, coins, amulets and other objects associated with burial practices.

These objects can tell us much more than what people owned.

They can provide clues about beliefs, cultural connections, trade and social practices.

A small piece of jewellery, for example, can reveal connections with another part of the Mediterranean. A ceramic object can provide information about trade routes and manufacturing techniques.

In archaeology, even seemingly ordinary objects can become important pieces of a much larger puzzle.

The Gods of Ancient Ibiza

Religion played an important role in ancient life, and the discoveries at Puig des Molins reflect the beliefs of the communities associated with the cemetery.

The Phoenician population of Ibiza had religious traditions connected to the wider Phoenician world, while later cultures introduced their own beliefs.

One particularly important figure associated with ancient Ibiza is Bes, a deity whose name is connected to the ancient name Ibossim.

The island's religious history continued to evolve as different civilizations arrived and settled.

The necropolis provides evidence of this changing cultural landscape.

A Window Into Everyday People

Ancient history often focuses on rulers, wars and major political events.

A cemetery can tell a different story.

The remains and objects found at Puig des Molins help researchers understand ordinary people who lived in Ibiza thousands of years ago.

What did they wear?

What did they believe?

How did they bury their relatives?

What objects mattered enough to accompany someone into death?

These questions make the site feel surprisingly human.

Behind every archaeological discovery was a real person who lived in the same Mediterranean landscape that visitors explore today.

The Necropolis Outlived Civilizations

Perhaps the most remarkable thing about Puig des Molins is the length of time represented there.

The cemetery was used through different historical periods, including the Phoenician and Punic eras and later periods of Roman influence.

Political powers changed.

Languages changed.

Religious traditions changed.

The city itself changed.

But the necropolis remained part of the landscape.

This makes it an extraordinary record of Ibiza's transformation over centuries.

Why Is It Called Puig des Molins?

The name Puig des Molins can be translated roughly as “Hill of the Mills.”

The name reflects the windmills that once occupied the hill.

That creates an interesting contrast between the site's more recent identity and its ancient history.

Today, the hill is associated with archaeology and the origins of Ibiza. But its landscape has continued to serve different purposes throughout the centuries.

The name itself is therefore another small reminder that places can accumulate layers of history.

The Ancient City Is Still Under Your Feet

One of the most exciting things about exploring Ibiza Town is realising that the modern city sits on top of an extraordinarily old landscape.

Modern streets occupy areas that have been inhabited, travelled through and used by different communities for thousands of years.

At Puig des Molins, that hidden history becomes tangible.

Instead of simply reading about ancient Ibiza, you can stand in a landscape where the archaeological evidence remains.

It changes the way you see the rest of the city.

A Different Side of Ibiza

For visitors who know Ibiza primarily for beaches and nightlife, Puig des Molins can completely change their perception of the island.

Here, there are no superclubs or luxury yachts.

There are tombs, archaeological remains and evidence of people who lived more than two thousand years ago.

Yet this is precisely what makes the experience so valuable.

Ibiza has never been just one thing.

It has been a trading centre, a maritime settlement, a fortified city, a religious community, a farming island, a cultural meeting point and, much later, an international holiday destination.

The underground tombs of Puig des Molins are one of the places where that much older Ibiza comes closest to the surface.
