Origins: why the Catacombs of Paris were created

Underground quarries turned into ossuaries

The history of the Catacombs dates back to ancient times. limestone quarries used to build Paris—often without rigorous planning or monitoring. These quarries, which were mined from the Middle Ages until the 18th century, left behind a network of unstable underground tunnels. 

Around 1774, several house collapses served as a reminder that these quarries posed a danger to the surface. 

A solution to a health and funeral crisis

At the end of the 18th century, Parisian cemeteries were facing a serious problem: overcrowding, poorly decomposed corpses, and risks to public health. 

To remedy this, the city decided to transfer the bones to the old underground quarries—a massive operation that began in 1785 with nighttime convoys from cemeteries, notably the Innocents Cemetery. 

Gradually, these underground chambers lost their original purpose and became a monumental ossuary, intended to house the remains exhumed from cemeteries.

Birth of the Public Catacombs

The site was officially designated as a municipal ossuary in 1786. 

After some renovations, the Catacombs opened their doors to the public—first by appointment in 1809, then gradually on a more regular basis from the mid-19th century onwards. 

The last transfer of remains took place in 1860. Since then, the ossuary has been frozen in time, becoming a place of remembrance, contemplation—and wonder for visitors. 

What the Paris Catacombs are today

A unique ossuary in the world

The Catacombs of Paris house the remains of more than six million people — a veritable underground necropolis. 

However, the part accessible to the public represents only a very small fraction of the total underground network. 

The official route is approximately 1.5 to 1.7 kilometers and is located at 20 meters below the surface, accessible via 131 steps down and 112 steps up. 

A unique atmosphere

During the visit, you walk through galleries decorated with bones—skulls, femurs, tibias—arranged with strange care, forming walls of “bone stone” and macabre “hedges.”. 

Plaques, inscriptions evoking death, quotations, sometimes sculptures or discreet works of art—everything contributes to a solemn, almost mystical atmosphere. 

This immersion into the ’empire of Death“ — according to the mythical inscription at the entrance — is as fascinating as it is thought-provoking. 

A place steeped in history and memory

Beyond the thrill, the Catacombs are a historical testimony : they tell both the urban history of Paris (quarries, collapses, the evolution of the city) and the management of the dead (health crises, exhumations, collective memory). 

Entering the Catacombs means coming face to face with millions of anonymous souls—an experience of contemplation, of reflection on mortality, time, and history.

Why are the Catacombs so fascinating?

A unique experience combining history and thrills

Few monuments offer the emotional and historical intensity of the Catacombs. You literally walk among the bones of millions of people—a tangible link to the past, to oblivion, to memory. This immersion evokes a mixture of respect, fascination, and sometimes fear—an experience that is both sensitive and intellectual. 

A remarkable underground heritage

The Catacombs are not just an ossuary: they also bear witness to the underground quarries and the geological and urban history of Paris. They remind us that beneath the modern city lies an ancient world, sculpted by centuries of exploitation. 

A living museum — but a fragile one

Every year, the ossuary attracts several hundred thousand visitors—in 2023, the number was around 607,730 visitors. 

But this high visitor traffic poses a conservation challenge—the bones, humidity, stale air, wear and tear—the site sometimes needs to be maintained and restored.
