Visiting Paris Catacombs: The Dark History Tourists Don't See

Share this article

Even above ground, Paris has always balanced on the edge of the abyss. In 1774, the Rue d’Enfer (literally the “Road to Hell”) cracked open into a thirty-meter chasm, swallowing houses and livestock. Alarmed, Louis XVI commissioned inspectors in 1777 to map and reinforce the subterranean quarries now threatening the city. Those miners discovered an immense network of tunnels: an underground city. At midnight in modern Paris, an iron grate might rise and a man’s flashlight would appear. These are the cataphiles: Paris’s most devoted spelunkers, who treat the city’s bones as “just another Friday night out”. Deep below the boulevards, they inhabit a vault known as the Empire of Death: roughly 280 kilometers of ossuary caverns winding under Paris’s streets.

Memory and Myth

This hidden realm was born in the late 18th century, when overflowing cemeteries made Parisians sick. In 1780 the monarchy banned burials within the city walls; by 1785 priests and ox-cart teams began nightly processions carting all the city’s corpses into the quarries outside Paris.^[1] Over six million skeletons (peasants and princes, saints and scholars) were emptied into those tunnels. Under Napoleon’s engineers, skulls and femurs were artfully stacked into walls and arches, a demented cathedral of bone complete with cryptic Latin inscriptions and bone chandeliers. In 1809 Napoleon himself theatrically opened the ossuary to the public. By 1814 Paris’s dead, from nameless paupers to Charlotte Corday (Marat’s assassin) and the courtesan Madame du Barry, lay interred here. Even Princess Élisabeth, sister of Louis XVI, rests quietly in the dark. Paris is literally built on fragile foundations: one underground plaque warns, “Think of the morning as if you might not make it to the evening, and of the evening as if you might not see the morning”.

The Guillotine Waltz

Paris’s romance with violence long predates these tunnels. Even as it exploded with Enlightenment culture, the city also toppled its monarchy in the Revolution. In January 1793 Louis XVI himself lost his head at the Place de la Révolution (now Concorde),^[2] and nine months later Marie-Antoinette met the same fate. The Reign of Terror that followed slaughtered thousands. By 1797 a macabre carnival took hold: society’s mourning became spectacle at the bal des victimes. Noble ladies who had lost relatives to the guillotine cropped their hair into a coiffure à la victime and tied red ribbons around their necks as if freshly beheaded. Spectators wrote that dancers even jerked their heads in rhythm to symbolize a collective decapitation. What was citywide grief became high-society parody, a grim defiance danced waltz after waltz.

That bloodletting did not stop with the Revolution. In 1871 Paris would rebel again under the banner of the Commune. For two months the working class took over City Hall, but in May the uprising was crushed in the Semaine Sanglante. Government troops summarily executed between ten and twenty thousand Communards. Today a single plaque at Père Lachaise marks the spot where 147 captured rebels were shot on May 28, 1871. In its final frenzy the Commune even executed the Archbishop of Paris and roughly a hundred other hostages. Only 95 of its leaders were formally tried and sentenced, but by then the streets and cemeteries already held thousands of corpses. The 1871 slaughter felt like the Revolution all over again: revolution betrayed by blood.

Innocence Lost

The carnage of Paris was not confined to battlefields and cobblestones. Even infants could not escape its dark chapters. By the fin-de-siècle, Parisian newspapers regularly screamed of newborns murdered at home. Accounts of “Encore un infanticide!” were common as the city recoiled in horror. One historian of the Third Republic notes that crimes against children, especially infanticide, rose as other crimes fell: the annual count of killed newborns nearly doubled (from about 110 to 220) between the mid-1800s and 1880s. Society struggled to explain this plague of private violence: was it poverty, shame, or the by-product of a frantic modern life? Whatever the cause, the blood of innocents stained Paris’s image of romance and reason. 19th-century Paris celebrated la vie bohème, but its darkest corners had become places where even mothers made murder. In a city obsessed with love letters and l’art pour l’art, the specter of infanticide was a reminder that Paris had an underbelly of desperation and despair.

Paris’s Underground Resistance

In the 20th century Paris’s underground passages passed from folklore into subculture. Starting in the 1980s a new generation “rediscovered” the catacombs. Calling themselves cataphiles (lovers of the catacombs), they began mapping the tunnels and turning chambers into secret venues. The community is eclectic: art students, anthropology grads, engineers and risk-takers slip below ground. Armed with homemade maps, they carve stone into absurd creations: miniature castles, mosaic disco balls, even tiled chapels hidden behind debris. Some passages have become sites of clandestine celebration. In recent years cataphiles have quietly staged underground birthday parties, Halloween raves and even techno dances among the skulls. One reporter noted that enthusiasts will even share raclette dinners and baguettes by headlamp or “walk their dogs for hours” in the catacombs.

For many, the thrill is freedom itself. “There are no rules: I can walk around in my bra if I want and no one cares,” shrugs a 25-year-old explorer, describing a surreal world where city ordinances disappear. One veteran says the catacombs feel “like the Upside Down from Stranger Things“: an inverted Paris where every familiar landmark has a skeletal shadow. Each midnight descent feels both festive and spiritual: cataphiles light candles at makeshift altars, dance in front of bone walls, even share ghost stories deep beneath the city. “For us it’s about curiosity, adrenaline and passion,” explains one veteran spelunker. In fact, cataphiles have coined their own lexicon of events: a wild underground carnival might be called a “cata-carnival,” and races between manholes a “cata-sprint”. In these echoing halls each skull becomes a page of Paris’s history and each spray-painted stencil a graffito of modern rebellion.

Above ground, official Paris barely acknowledges this secret world. Guided tours allow visitors to see only about 1.5 kilometers of ossuary galleries near the Denfert-Rochereau entrance: a short, lighted loop through neat stacks of bones. The remaining 278 kilometers of tunnels are off-limits, patrolled by miners and police. (Technically, trespassing down here is only a misdemeanor, punishable by roughly a €60 fine, but cataphiles call that the “price of admission.”) Word-of-mouth, social media and guidebooks still lure hundreds of new explorers into the tunnels each year. For them, the risks add to the mystique: one legend holds that only one man has ever died in the Catacombs by accident. In 1793 a doorman named Philibert Aspairt disappeared under Denfert-Rochereau; his skeleton was found 11 years later at the bottom of a staircase. His bones lie silent testimony that even these Empire of Death tunnels had treasures yet undiscovered.

These underground rebels even echo the city’s insurrections. Remarkably, in 1944 Colonel Henri Rol-Tanguy of the French Resistance based himself in the Catacombs to help coordinate the uprising that would liberate Paris. In other words, Paris’s spirit of revolt quite literally continued in the depths.

All told, the secret City of Death has become a paradoxical magnet: by some counts “hundreds of thousands” have visited the forbidden galleries. Cataphiles say it’s an “absolutely huge” subculture, one that converts tragedy into a living memorial. When these young Parisians dine on bread and cheese amid centuries of bones, they are not ghouls but pilgrims connecting with history. The catacombs are their Paris in microcosm: every bit as democratic as the Republic above. Descending among the dead, they find that Paris’s rebellious soul is present in concrete and cartilage: a century of beheadings, barricades and abandoned infants, all smiling back on them from marble skulls.

Memory and Myth

Even Paris’s literature nods to this obsession. In Hugo Lunny’s novel A Story in Paris, a mild wine-shop clerk becomes haunted by the tunnels; each night he shuffles below the city to commune with those buried miles underfoot. Lunny’s eerie tale literally mirrors reality: above ground Paris dazzles with cafés and lovers, while below its streets lie the silent remnants of both revolution and sorrow. In the catacombs, Paris has physically inscribed its history: Royals and radicals in adjacent alcoves, all anonymous in the end.

What all this means can be hard to pin down. The Catacombs began as a grim public health measure (the line “Arrête! C’est ici l’empire de la Mort” even warns visitors of mortality) but over time they became something more: a bone-bound encyclopedia of the city’s extremes. Walking among the piled femurs is like reading Paris’s biography in Gothic lettering. As one sign reminds us, each dawn truly should be a gift. Yet Parisians downplay this gothic subplot. The underground is now one of the city’s hottest tourist draws: in fact Paris’s third-most-visited attraction after the Louvre and Eiffel Tower^[3], and the old warning has become a T-shirt slogan.^[3] It’s fittingly ironic: the “Empire of Death” is now a kitsch branding, a grim souvenir of civic pragmatism.

In the end, Paris’s story remains lit by many lamps. The boulevards blaze with lights of art and love, while below there’s a flicker of candlelight among the bones. In the City of Light, beauty and brutality have always shared a cradle, and sometimes a dance floor, too. For the cataphiles, as for the city itself, sex and blood remain entwined in the code of survival. Descending through that manhole in the street, they remind us: beneath the glamour of Paris still rolls the quiet current of its own brutality, the city’s past waiting, ever present, underfoot.
