Paris Catacombs: reopening in spring 2026 with an immersive tour and a unique sound experience

After several months of work, the Paris catacombs will reopen their doors in spring 2026. This legendary site, which attracts hundreds of thousands of visitors every year, now offers a redesigned experience. History buffs and thrill-seekers can finally rediscover this unique underground labyrinth.

A long-awaited reopening for the Paris catacombs

The renovation project lasted several months. During this period, the teams modernized the infrastructure while preserving the authenticity of the site. As a result, visitors now enjoy a smoother, better-adapted tour.

This temporary closure enabled us to rethink the way we welcome the public. In addition, safety standards have been tightened to ensure a worry-free visit. The work also involved the lighting and ventilation of the galleries.

The City of Paris has invested in this major project. As a result, the Paris catacombs now offer a setting that is both respectful of heritage and modern. This transformation meets the expectations of both French and international visitors.

“This fascinating place deserved a showcase to match its exceptional history.”

A unique immersive audio tour

The great novelty of this reopening lies in the immersive audio headsets. These devices now accompany every visitor throughout the tour. However, they are optional for those who prefer silence.

Thanks to this technology, the history of the ossuaries comes vividly to life. Stories evoke the origins of this 18th-century site. Sound testimonies recreate the atmosphere of the time.

• Immersive audio headsets available in several languages
• Renewed scenography to make the route easier to understand
• Optimized lighting highlights bones and galleries
• Improved signage for easier underground orientation
• Enhanced accessibility for people with reduced mobility

Six million bones under the capital

The catacombs of Paris house the remains of over six million Parisians. These bones come from the city’s former cemeteries, transferred between 1786 and 1860. As a result, this site represents the world’s largest underground ossuary.

The transfer of the bones began in response to the insalubrious state of Parisian cemeteries. The saturated Cimetière des Innocents was threatening public health. So the authorities decided to use the old limestone quarries beneath the city.

Over the decades, the site has acquired a mystical dimension. Famous personalities may be buried here, but it’s impossible to identify them. Yet this uncertainty contributes to the strange charm of this unusual place.

The route open to the public is around 1.5 kilometers long. However, the entire network of former quarries represents over 300 kilometers of galleries. As a result, only a tiny part of the network remains accessible to visitors.

Redesigned visiting conditions

Online booking is becoming almost indispensable for access to the Paris catacombs. The daily capacity remains limited to preserve the site. From now on, time slots will allow a better distribution of visitors.

Admission remains affordable, with discounts for young people and the unemployed. What’s more, the first Sunday of every month is free. This pricing policy promotes access to culture for all.

Underground temperatures are around 14 degrees all year round. So it’s a good idea to bring warm clothing, even in summer. The 131 steps of the spiral staircase also require good physical condition.

A world-renowned heritage site

The catacombs of Paris are among the capital’s most visited monuments. Every year, some 500,000 people descend into these galleries. This figure makes the site one of Paris’s must-sees.

The international reputation of this site continues to grow. Tourists come from all over the world to discover this unique ossuary. Social networks have also helped to popularize these galleries among the younger generation.

The attraction of Paris’ underground heritage goes beyond official visits. Enthusiasts, known as cataphiles, clandestinely explore the forbidden network. Yet this practice remains illegal and dangerous.

This spring’s 2026 reopening marks a new stage for the Paris catacombs. The improvements promise an enriched and memorable experience. This legendary site continues to fascinate generation after generation.
