The Paris Catacombs are former stone quarries located beneath Denfert-Rochereau Square, housing the bones of approximately 6 million people since the 18th century; in the 2-kilometer section open to visitors, bones are arranged in geometric patterns.
The Paris Catacombs are part of an ancient quarry network extending 20 meters deep beneath the city. Bones were brought here at the end of the 18th century when city cemeteries were moved. Today, the remains of over 6 million Parisians are stacked in orderly rows. Skulls and bones are arranged to form patterns, crosses, and heart shapes in some sections; this arrangement was made in the 19th century.
The tour takes about an hour, passing through narrow and dimly lit tunnels. The ground is gravelly, and the ceiling is low in some sections. Comfortable shoes are important. Visitors note that the included audio guide explains the city's history well, enriching the experience significantly. For those visiting alone, the dim light can be a bit eerie; some comments suggest that going in a group is more comfortable.
The site closed for renovation in November 2025 and reopened on April 8, 2026, with a renewed arrangement. Some visitors write that its new state has lost its old character and that the price has also increased. It gets crowded at the entrance, so it is necessary to purchase a timed ticket.

Guide's Note
The vast majority of visitors to this historic site, located beneath Paris and containing the bones of 6 million Parisians, leave deeply impressed by the experience. Walking through long corridors and suddenly encountering walls of skulls and bones is described by many as an atmosphere that is both eerie and inspires deep respect for history. The visit lasts approximately 1.5 hours; the audio guide provided during the tour significantly enriches the experience by explaining why and how the site was created.
On hot summer days, the constant 14-degree Celsius temperature underground is noted by many visitors as a pleasant surprise. Regarding children, the general consensus is that the site is suitable for ages 10 and up; it is not recommended for younger children. The surrounding neighborhood is also considered worth exploring.
Things to note:- Tickets sell out very quickly, especially during high season; it is recommended to purchase them at least a week in advance, from the official channel or reliable third-party sites.
- There are many stairs on the way down and up; this can be challenging for those with knee problems or mobility limitations, but it is noted that proceeding without rushing largely reduces the problem.
- Some sections are quite narrow; those with claustrophobia and tall visitors should be prepared for this in advance.
- Even in summer, it is recommended to bring a cardigan or a light jacket.
- One visitor expressed that the AI-powered exhibition content used at the site was not appropriate for the location and its history; visitors with different expectations in this regard may be disappointed.
- Waiting times can sometimes be long.
When to Visit?
When Paris streets are hot and crowded in summer, the underground remains consistently cool. Visitors therefore particularly recommend summer tours. To reduce queues, it makes sense to get a timed ticket for the early hours of the day. Demand is higher on weekends and during school holidays.
How to Get There?
The entrance is at Denfert-Rochereau square. Metro lines 4 and 6 reach here directly, and RER B is also an option. It takes approximately 25 minutes from the Eiffel Tower. Metro services start at 5:30 AM every day; check night hours for your return.
How Much Time to Allocate?
The time spent inside the tunnels is approximately one hour. This does not include waiting in line and gathering outside. If you have a timed ticket, this time is shortened. It can easily be fitted into a half-day Paris itinerary.
Things to Consider
The ground is gravelly, and the ceiling is low in some passages; do not choose high heels or non-breathable soles. Lighting is dim, so it may not be suitable for those with heart conditions or claustrophobia. Some visitors note that taking selfies in the area where the bones are located is considered disrespectful. It is important to remember that this is a monumental cemetery.
Photo Spots
The sections where bones are arranged to form crosses, hearts, and geometric patterns are the most photographed parts. Since the light is low, flashless shooting or the night mode of a phone camera yields better results. Tripods and large equipment are generally not allowed.
Things to Know
The site closed for renovation in November 2025 and reopened on April 8, 2026, with a new arrangement. Some former visitors write that the new arrangement creates a different atmosphere from its previous state and that prices have also increased. Remember that the entrance fee can quickly increase the total cost for families; budget in advance for large groups.
How to Add to Your Itinerary?
Denfert-Rochereau is close to Montparnasse and the Luxembourg Gardens. It makes sense to combine a Catacombs visit in the afternoon, followed by city views from the Montparnasse Tower. Allocating morning hours for sunnier and open-air venues and placing the underground visit in the middle of the day also works for those looking to cool down.
