Haunted Catacombs Of Paris: How To Explore The World's Largest Grave

Next time you take a stroll through the French capital, remember this: below you run miles of underground tunnels beneath Paris, filled with the remains of six million people in their final resting place – the haunted Catacombs of Paris.

Experiencing a descent into the "Empire of Death" is one of those experiences that remain memorable far after they're over, and those of us who have visited the Catacombs usually recall the visit as one of the most intense places we visited in Paris.

What are the Paris Catacombs?

This is an eerie place, one of the most haunted places in Paris.

You'll be thrilled by your visit if you're keen on the city's history, or interested in the potentially paranormal.

But you'll also relish the experience if you're simply looking for something fascinating when the weather is uncooperative, or if you're looking for an off-the-beaten-path discovery.

Skulls are positioned in many different ways in the Catacombs of Paris

The Catacombs under Paris are by no means the only crypts or catacombs in the city – there are several others under churches and in cemeteries throughout Paris, but the Catacombs are by far the largest.

Only a tiny portion of the underground is open to the public, but those tunnels that are accessible are well worth the visit, as long as you don't mind the dark, dank and potentially macabre.

And many people don't: for example, ghost tours in Paris (which often include the Catacombs) are a major tourist attraction, and a good tour of Catacombs in Paris sells out quickly.

History of the Catacombs of Paris 

The history of the Paris Catacombs begins not with death but with stone. These tunnels were limestone quarries long before they became ossuaries, supplying much of the stone used to build medieval Paris.

In Roman times, open-air quarries existed throughout the region, well beyond the city limits of what the Romans called Lutetia, long before it became the French capital.

People helped themselves to the stone, first for their humble dwellings, but once the Middle Ages rolled in, to build their huge cathedrals as well.

After all, why transport stone from far away when so much limestone could be found so easily just beneath their feet?

The city spread until it found itself right above the quarries, but constant excavations weakened the ground, creating an unregulated underground labyrinth that threatened to collapse.

Sometimes, it did, like the infamous 1777 collapse on the Rue d'Enfer, which swallowed up an entire house.

Worried about the ground under the city of Paris, authorities set up a General Inspectorate of Quarries (it still exists) to check on their stability and to prevent anyone from digging new ones.

Meantime, the city's cemeteries were filling up.

Paris was expanding, population was growing, and the city's 200 graveyards could no longer keep up with the demand for space. Each time a new grave was dug, bones would be found underneath.

The sheer weight of all these bodies was straining the grave walls until finally,  in 1780, an entire chunk of the Cimetière des Saints-Innocents, the largest in Paris, gave way, right into the basement of a local restaurant.

Collapse was not the only danger.

The entire setup was utterly insalubrious, the many mass graves becoming sources of infection and illness, smelling of putrefaction and polluting the wells from which people got their drinking water.

As the citizenry howled, Paris finally did something about the overflowing cemetery: it moved the buried remains to the former quarries of Tombe-Issoire, in what is now the 14th arrondissement. And that's how it all began.

The bones were carried in the dead of night to avoid scaring the city's respectable burghers. One can only imagine such a death procession, with priestly robes floating past by torchlight, accompanied by the squeal of heaving carts and the whispered blessings of the clergy as the cortège moved forward.

Transporting all the bones would eventually take a full 12 years...

The first bones under Paris were moved in April 1786, and more would be added over time, as other cemeteries filled up. By 1814, when the limestone quarries finally closed, the miles of tunnels under Paris would be home to some six million souls.

Despite being ossuaries, they came to be known as the "Catacombs", in reference to the underground necropoles in Rome. (Eventually, excavations during the 1960s would yield even more remains, which would also find their way here.)

The Paris Catacombs were opened to the public on 1 July 1809 with great fanfare, creating a stir among the glitterati who visited − these included such contemporary luminaries as Napoleon III and the Emperor of Austria.

A Catacombs map of Paris helps explain how the tunnels mirror the street grid above, often preserving the names of vanished roads and neighborhoods.

How to visit the Catacombs of Paris

The official circuit covers about 1.5 kilometers (just under a mile) and takes around 45 minutes, though many visitors stay longer to examine the inscriptions, bone arrangements and quarry markers.

The section now open to the public is called the Ossuary of Denfert-Rochereau, across the street from the metro station of the same name. (Denfert-Rochereau, by the way, was a military leader who led the heroic resistance of the city of Belfort in 1871 during the Franco-Prussian War.)

No question: the haunted Catacombs of Paris are one of the more unusual places to see in Paris.

If you plan to visit the Catacombs of Paris, book ahead. Timed-entry tickets often sell out, especially during school holidays and weekends.

Scary catacombs: Are the Paris Catacombs haunted?

It's a simple journey, beginning with a corkscrew stairway that plunges you 20 meters underground. There's no avoiding this – there are no elevators.

After looking around a well-lit room filled with information and displays, the hush begins. A pseudo-grand entrance leads you into the Catacombs with these words: "STOP: This is the Empire of Death."

Not discouraging, but not quite welcoming, either. They're not called the haunted Catacombs of Paris for nothing.

Catacombs entrance, Paris. The sign says: "STOP! You are entering the empire of death."

Know that you'll be walking through lengthy dark tunnels of humid earth for quite a while before reaching the actual ossuary, so claustrophobes should abstain, as should those who have difficulty breathing. (That said, the six-month renovations in 2025-2026 go a long way towards improving lighting and air quality.)

As you advance, any noise will become more muted and muffled, enveloping you in the silence of the earth beneath. The path forward is relatively well marked, but don't wander off, because there is no phone signal down here and if you get lost...

One of the favorite urban legends concerns a certain Philibert Aspairt who edged into the depths  of the Catacombs in 1793 but never found his way out (you can read more about him below).

Who knows if his ghost isn't still wandering around...

Bones as art

You'll see plenty of astonishing things: bones built up into unusual shapes and structures, signs with names of the streets above, small rooms with vaults...

Rather than the grim and gory scenes you might expect, the bones have been positioned to please, a decision made long ago by the then General Inspector of the Quarries, Louis-Étienne Héricart de Thury, and improved upon during the renovations. He set up the bones as museum pieces, with spectacular architectural structures such as doric columns, commemorative plaques, altars – and unusually shaped structures, many of which are considered works of art.

Had he been at work today, some of the more whimsical constructions would definitely not have been considered in good taste for 21st century sensitivities.

The sculptures of the Catacombs

While much of what there is to see is made up of bones, I found several unexpected sculptures as I wandered through the tunnels, but I'll let you discover those for yourself.

There were also some I did not see, mostly carved in the late 18th century between 1777 and 1782 and hewn by a certain Décure, a quarry worker with the General Inspectorate.

A former army veteran, he had fought for the liberation (from the English) of Minorca, in the Balearic Islands, and was imprisoned for a time at Port Mahon, the island's capital.

While working in the quarry, he discovered a cavern that had opened after a rockfall. At lunchtime, while his colleagues returned above ground for lunch, he would enter "his" cavern and chip away at the rock. For five years, he fashioned buildings underground that reminded him of those of Mahon.

Sadly, some of the wall sculptures were damaged during the French Revolution, which would break out shortly after his death, and, in later years, by nature and people, although much has been restored.

These "additional" caverns aren't always open to the public, although they do allow some visits on special occasions.

More sculptures to see when visiting the catacombs in Paris

Is it legal to go into the Catacombs of Paris? Yes. And no.

Long before the Catacombs became commercialized, electrically lit and properly mapped, people wandered down here to explore these creepy places freely. Eventually, the Catacombs were partly cordoned off, with only a portion now available to visit.

Some people still insist on exploring beyond these "permitted" areas, however.

The cataphiles of Paris

There are many Paris Catacombs stories, and with only a small portion of the tunnels open to the public, it is inevitable that adventurers will want to explore the rest.

They have come to be known as cataphiles, passionate visitors of the forbidden underground.

People have been visiting the tunnels for centuries but wandering off the official paths has been illegal since 1955.

Many cataphiles became particularly active during the May 1968 street revolts, when students used the Catacombs to circumvent police barricades. By the 1980s, some underground chambers were so crowded their party music clashed with that of neighboring tunnels.

Authorities eventually sealed off most of the entrances. The number of cataphiles dwindled, and only the most passionate remained.

That said, the arrival of Covid-19 had an unexpected effect on the Catacombs: it encouraged illegal gatherings away from curfews.

These days, authorities are watchful.

Being a cataphile is not risk-free

There's no question security is an issue.

The possibility of getting lost exists, of course, and there's no phone signal down there.

There be rats. Of course. We're underground.

The tunnels could flood or cave in, because not all the tunnels have been reinforced. And you can't assume all cataphiles are friendly. Muggings underground are not unknown.

Cataphiles and catacops

Since 1980 a special police brigade has been patrolling the Catacombs, looking for cataphiles.

Several times a week, they head into the tunnels, hoping to dislodge a few insistent cataphiles.

They look for clues − cigarette or marijuana butts, the smell of fresh paint from tags, the sound of distant music from an underground party − and often, they find people and parties.

One night, they stumbled upon an entire discotheque with 300 guests.

The fines can range from €60 into the thousands.

In 2004, they discovered a motion-sensor recording of dogs barking, designed to keep people away, along with a huge cavern equipped as a cinema, with a bar and restaurant next door. When they returned a few days later, everything had been disconnected and a note left behind: "Do not try to find us."

And while their primary job is finding illegal visitors, the police also check on the tunnels themselves, to make sure nothing has shifted or is in danger of collapse.

Haunted Catacombs of Paris: the legend of the cat skulls

Let's leave the cataphiles and focus on the cats.

Many Paris Catacombs legends may be true, or not, but the story of the cats' skulls is guaranteed to give you chills. It is to be found in a book about underground Paris, which revealed an 1896 discovery of hundreds of skulls in the tunnels. Cat skulls.

It seems the Catacombs shared a well with a nearby restaurant, undoubtedly run by an unscrupulous manager who passed off felines as rabbits, their taste apparently similar.

This being an unacceptable practice, disposing of cat carcasses in the well isn't, well, inconceivable. Yet another of the creepy stories are told about the Catacombs...

A CATAPHILE ADVENTURE

This video documents a foray into the forbidden Catacombs of Paris. It's not something I recommend, but you can see for yourself...

The hidden uses of the Catacombs

As cataphiles became familiar with the tunnels, they often returned to the same rooms and eventually made themselves at home, decorating walls, bringing down furniture, adding street art to the walls and naming their secret rooms according to purpose or decor − La Plage (the beach), Le Cellier (the cellar) or La Salle du Château (the castle room).

The high-ceilinged "Room Z" may have been a gathering place for a right-wing splinter group in the 1930s, and was the scene of massive parties in the 1980s.

The Catacombs have been used to grow mushrooms, to meet for illicit sex, or even as nuclear shelters.

During the German occupation of Paris in World War II, both the French Resistance and German forces used sections of the underground network, turning the Catacombs into a strategic space. The Germans even built a bunker down there, complete with electricity, reinforced doors and toilets.

And until the 1970s, a mass was celebrated down here each year for the Day of the Dead.

Sadly, the Catacombs are not immune to vandalism and regular clean-ups are needed to get rid of the worst messes. A few years ago, vandals caused much destruction several months were needed for repairs.

A few scary facts about the Catacombs of Paris 

• The tunnels run some 250-300 km (155-186 mi) under Paris. The ossuary, the part where the bones are kept, accounts for some 1.7 km (1 mile). The passageway is about 1.8m high (6 ft), although I'd quibble about this in some parts, where I was sure I could feel the ceiling not far above my head. The temperature is a uniform 14℃ (57℉) so don't forget your sweater.

• The tunnels are well lit but I felt better having a flashlight. What if there was a power failure? (Here's the one I ues.)

• Good walking shoes are a must, not only for the stairs but because of the humidity on the ground.

• People actually try to steal some of the bones, despite a video camera on almost every corner throughout the Catacombs.

• Did you know there's a Catacombs Paris movie? It's called As Above, So Below, and is a Blair Witch-type shoot of a trip down below. It tells catacombs horror stories so no, I haven't seen it.

• You can visit the Catacombs of Paris on your own or with an audio guide. Frankly, I didn't find the audioguide particularly helpful, although it did point out one or two things I might have missed otherwise  − at 5 euros for the guide, we're looking at 2.5 € per fact, added to the steep entrance fee. (Click here to get your tickets for Catacombs Paris.) If you'd rather be with a smaller group, this Paris Catacombs tour might be the answer.

• This is also one of the fun things to do in Paris with kids! While there's no minimum age limit, it's not recommended for children under 10.
