What Is the Paris Catacombs?

The Paris Catacombs is an underground ossuary built inside a section of the city's former limestone quarries, in the 14th arrondissement near Place Denfert-Rochereau. The tunnels themselves predate the bones: Parisians had been mining stone from beneath the Left Bank for centuries before the quarries were repurposed for an entirely different problem — the city's cemeteries were overflowing, and in 1780 a collapsing wall at the overcrowded Holy Innocents' Cemetery in central Paris forced the issue. Starting in 1786, the remains of Parisians were exhumed and transferred underground by torchlight procession, cemetery by cemetery, over roughly two decades.

What visitors see today is the result of that transfer: an estimated six million sets of remains, many arranged into deliberate walls and patterns by early 19th-century curators rather than left as a simple pile. The ossuary opened for occasional visits not long after, and it remains one of the largest ossuaries anywhere in the world — a genuinely unusual sight, not a recreation or a themed attraction.

Tickets & Prices 2026

The Paris Catacombs sells three paid ticket tiers, all including the audio guide. The full rate is €31. The reduced rate is €25, available to visitors aged 5 to 26, students, Paris Pass Famille holders, and members of certain French heritage and archaeology organizations with valid ID. A child rate of €15 covers ages 8 to 17, and children under 8 enter free. A standalone audio guide, for anyone visiting on a free-entry ticket, costs €5 separately.

Free admission applies to people with disabilities and one companion, jobseekers, certain social benefit recipients, Paris city employees, professional visual artists, museum professionals, journalists, and members of organizations such as ICOM and ICOMOS, all upon presenting valid documentation. One catch worth knowing before you plan around it: free-rate tickets cannot be booked online, even when the calendar shows availability — you present your credentials at the ticket desk on the day and are admitted regardless of whether online slots are sold out.

For every paid ticket type, online booking is strongly recommended rather than optional in practice, since walk-up availability on a busy day is unpredictable.

Opening Hours & Best Time to Go

The Catacombs are open Tuesday to Sunday, 9:45am to 8:30pm, with last admission at 7:30pm. It's closed on Mondays and on January 1, May 1, and December 25, but stays open on other French public holidays — July 14, August 15, November 1, and November 11 — when many other Paris sights run reduced hours.

Because entry is metered to keep the underground circuit at a maximum of 200 visitors at a time, even a booked time slot doesn't guarantee walking straight in — you may wait a few minutes at the entrance while the circuit clears. That wait grows substantially at busier periods. The first slots right at 9:45am are consistently the quietest, both for the entrance queue and for having more of the ossuary to yourself; mid-morning through mid-afternoon is the busiest stretch, especially on weekends and during French school holidays.

How Long to Plan

The visit itself takes about 45 minutes: a one-way, 1.5-kilometer underground circuit with no way to double back or skip ahead. There's no elevator — expect 131 steps down at the start and 112 steps back up at the exit, which is a different building from the entrance, several blocks away on Avenue René Coty.

Add time on either end. Even with a booked slot, budget for security screening and the entrance queue, plus the walk back to the exit building afterward. In peak season, an hour to an hour and a half door-to-door is realistic; off-season and on a weekday morning, closer to 45 minutes to an hour. The tunnels hold a constant 14°C (57°F) year-round, noticeably cooler than the street above even in summer, so a light layer is worth carrying regardless of the season.

How to Get There

The entrance is at 1 Avenue du Colonel Henri Rol-Tanguy, 75014 Paris, right on Place Denfert-Rochereau. The closest station is Denfert-Rochereau itself, served by Métro lines 4 and 6 and by RER B, putting the entrance a minute or two on foot from the platforms. It's roughly 20 to 25 minutes from central Paris by metro or RER, in the 14th arrondissement on the southern edge of the Left Bank, near Montparnasse rather than the Louvre-Notre-Dame cluster most first-time visitors base themselves around.

Remember that the exit is a separate building on Avenue René Coty, not the same door you entered through — plan your onward route from there rather than expecting to return to Denfert-Rochereau.

Visit Tips: Queues, Booking & Common Mistakes

Book online in advance for any paid ticket. Without a reservation, especially in summer or on a weekend, walk-up queuing can run well over an hour before you even reach the ticket window, on top of the wait to enter the circuit itself. Only holders of free-rate tickets should skip online booking, since that ticket type isn't sold online in the first place.

Pack light: suitcases and large bags aren't allowed, and only bags smaller than roughly 40 by 30cm are permitted inside, carried by hand or facing forward. Wear flat, sturdy shoes — the floor underground is uneven and can be slippery, and the passageways narrow in places. The site is not wheelchair accessible, and it's not recommended for anyone with claustrophobia or a cardiac or respiratory condition, given the confined, one-way nature of the route. Guide dogs are permitted for sight-impaired visitors, though white canes are not, and sight-impaired visitors are advised to bring a companion.

Once inside, don't touch the bones or the wall arrangements — it's prohibited and actively enforced. Smoking, eating, and drinking are also banned throughout the circuit, and camera tripods aren't permitted given the narrow passageways and visitor volume.

Nearby Attractions

The Catacombs sit apart from the classic central-Paris sightseeing loop, in the Montparnasse-adjacent 14th arrondissement rather than beside the Seine's major landmarks. If you're building a day that pairs the ossuary with central Paris, the RER B from Denfert-Rochereau runs directly to Saint-Michel–Notre-Dame, putting the Notre-Dame Cathedral within easy reach on the same trip.

From there, the Louvre Museum and the Musée d'Orsay are both a short metro ride further along the Left Bank, making a Catacombs-morning-into-museums-afternoon a workable combination if you start with the earliest entry slot. For a broader sense of what else is worth seeing beyond the headline sights, our guide to hidden gems in Paris has more offbeat picks in the same spirit as the ossuary itself.
