The Catacombs of Paris, a subterranean ossuary holding the remains of millions, are a captivating and morbidly fascinating landmark. But beyond the eerie beauty and historical significance, a common question lingers: just how extensive are these underground tunnels? Determining the exact length is more complex than a simple measurement, encompassing both the officially accessible area and the vast, uncharted network beneath the City of Lights.
Understanding the Catacombs: A Labyrinth Beneath Paris
To grasp the scope of the Catacombs, it’s crucial to understand their origins and evolution. They weren’t initially designed as a final resting place. Instead, they began as a network of limestone quarries, mined from the Roman era onward to provide the stone that built Paris. Over centuries, these quarries expanded, creating a labyrinth of tunnels under the city.
The Ossuary: A Solution to Overcrowded Cemeteries
In the late 18th century, Paris faced a severe public health crisis due to overflowing cemeteries. The Cimetière des Innocents, the city’s largest cemetery, was particularly problematic, posing a significant health hazard to the surrounding population. The solution was to discreetly relocate the remains from various Parisian cemeteries and mass graves into the abandoned quarry tunnels.
This transfer began in 1786 and continued for several years. The bones were meticulously arranged, often in decorative patterns, creating the ossuary we know today. The consolidation of remains into the Catacombs effectively addressed the public health issue while creating a unique and somewhat unsettling historical site.
The Network of Tunnels: More Than Just an Ossuary
It’s important to differentiate between the ossuary and the complete network of tunnels. The ossuary, the area containing the stacked bones and skulls, represents only a small portion of the total underground network. The tunnels extend far beyond the ossuary, forming a complex and often unstable web beneath Paris.
The Officially Accessible Catacombs: A Glimpse into the Underworld
The Catacombs open to the public cover a relatively small segment of the overall tunnel system. This section is carefully maintained and secured for visitor safety. It provides a controlled and informative experience, allowing people to witness the ossuary and learn about its history.
Length of the Publicly Accessible Section
The publicly accessible section of the Catacombs is approximately 1.5 kilometers (0.93 miles) long. The tour typically takes around 45 minutes to an hour to complete, moving at a moderate pace. While seemingly short, this section offers a powerful and memorable experience, showcasing the sheer volume of human remains and the history behind their relocation.
Visiting the Official Catacombs: What to Expect
When visiting the Catacombs, be prepared for a descent of 130 steps to reach the ossuary level, and then an ascent of 83 steps to exit. The temperature underground is consistently cool, around 14 degrees Celsius (57 degrees Fahrenheit), so bringing a light jacket is recommended. Photography is permitted, but flash photography is discouraged to preserve the bones.
Tickets should be purchased in advance online, as queues can be very long, especially during peak season. The number of visitors allowed inside at any given time is limited, so booking ahead guarantees entry.
The Unauthorized Catacombs: A Hidden World
Beyond the controlled environment of the official Catacombs lies a vast, unauthorized network of tunnels explored by urban explorers known as “cataphiles.” This network is significantly larger and more dangerous than the official section.
Estimating the Total Length: A Difficult Task
Determining the total length of the entire Catacombs network is an extremely difficult task. There are no official, comprehensive maps, and the tunnels are often unstable, flooded, or simply too narrow to navigate safely. However, estimates suggest that the network spans approximately 250 to 320 kilometers (155 to 200 miles). This figure includes all the tunnels, both those that once formed the quarries and those that were later used for various purposes.
Dangers of Exploring the Unauthorized Tunnels
Exploring the unauthorized Catacombs is extremely dangerous and illegal. The tunnels are unlit, poorly ventilated, and prone to collapses. Getting lost is a real possibility, and emergency services may have difficulty locating and rescuing individuals in the maze-like network. Furthermore, the presence of underground water sources and unstable ceilings adds to the risk. Those found in the unauthorized sections of the catacombs are fined.
The Culture of Cataphiles: An Underground Community
Despite the dangers and illegality, a subculture of cataphiles persists, drawn to the mystery and adventure of the unauthorized tunnels. These individuals often possess extensive knowledge of the Catacombs, navigating the network with self-made maps and specialized equipment. They are also known for creating art installations and organizing secret gatherings in the underground space.
Historical Significance and Preservation Efforts
The Catacombs of Paris are not just a collection of bones; they are a significant historical site that reflects the city’s past. They represent a practical solution to a public health crisis, a testament to the city’s resourcefulness, and a tangible link to the lives of millions who once lived in Paris.
Protecting the Catacombs: Ongoing Challenges
Preserving the Catacombs poses numerous challenges. The unstable nature of the tunnels requires constant monitoring and maintenance. Water infiltration, erosion, and vandalism are ongoing threats. Efforts are underway to reinforce the tunnels, improve drainage, and prevent unauthorized access.
The Catacombs as a Cultural Landmark
The Catacombs are a popular tourist attraction, drawing visitors from around the world. Their unique and macabre appeal makes them a must-see destination for those interested in history, urban exploration, and the darker side of Paris. They serve as a reminder of the city’s complex past and the fragility of human life.

The guided path provides a focused and informative glimpse into the history and purpose of the Catacombs.
What is the estimated total length of all the tunnels in the Paris Catacombs?
The entire network of tunnels composing the Paris Catacombs is estimated to extend for over 300 kilometers (186 miles). This extensive labyrinth underlies a significant portion of Paris, weaving its way beneath streets, buildings, and infrastructure. The network’s complexity makes it challenging to map completely, and the full extent may never be precisely known.
These tunnels were originally created through centuries of limestone quarrying, providing the stone used to build much of Paris. The vastness of the network is a testament to the scale of the quarrying operations and subsequently, the efforts to consolidate remains within this subterranean space. This extensive underground system continues to intrigue researchers and urban explorers alike.
Why were the bones moved into the Paris Catacombs?
The primary reason for moving bones into the Catacombs was to alleviate severe overcrowding and sanitation problems in Paris’s cemeteries during the late 18th century. The Cimetière des Innocents, the city’s largest and oldest cemetery, was particularly problematic, overflowing with bodies and posing a significant public health risk. The stench and potential for disease prompted authorities to find a solution.
The abandoned limestone quarries offered an ideal solution due to their ample space and relative seclusion. Beginning in 1786, remains from various Parisian cemeteries were systematically exhumed and transferred to the Catacombs. This process continued for several years, resulting in the ossuary as it exists today. The relocation aimed to improve sanitation and provide a more dignified resting place for the deceased.
Are the Paris Catacombs a single, continuous tunnel?
No, the Paris Catacombs are not a single, continuous tunnel. They are a complex network of interconnected tunnels, chambers, and galleries. These spaces were created over time through extensive limestone quarrying, resulting in a labyrinthine structure beneath the city. The network is characterized by its irregularity and varying dimensions.
While some sections may appear as long, straight corridors, others branch off into smaller, more intricate passageways. The structure’s complexity is further enhanced by the varying geological conditions and subsequent modifications made over the centuries. This intricate network is far from a simple, linear tunnel, adding to its mystique and challenge for exploration.
How deep below street level are the Paris Catacombs located?
The Paris Catacombs are generally located approximately 20 meters (65 feet) below street level. This depth places them beneath the foundations of many buildings and infrastructure within the city. The exact depth can vary slightly depending on the specific location within the network and the topography of the surface above.
This significant depth contributes to the cool, damp environment within the Catacombs. The distance from the surface also helps to isolate the ossuary from the noise and vibrations of the bustling city above, creating a sense of eerie tranquility for those who visit. The journey downward adds to the overall experience and perception of descending into another world.
Is it illegal to explore the Catacombs outside the authorized tour route?
Yes, it is illegal to explore the Paris Catacombs outside the designated tour route. These unauthorized areas are often structurally unstable and pose significant safety risks. The penalties for illegal entry can include fines and even arrest, as the authorities actively patrol and monitor the Catacombs.
Beyond the legal ramifications, venturing into the unauthorized sections is highly discouraged due to the potential for getting lost, injured, or encountering unforeseen dangers. The vastness and complexity of the network can quickly disorient even experienced urban explorers. Respecting the established boundaries ensures personal safety and helps to preserve the historical site for future generations.
What types of remains are found in the Catacombs?
The remains found in the Paris Catacombs primarily consist of human bones, including skulls and long bones, representing the skeletal remains of millions of individuals. These bones were transferred from various Parisian cemeteries during the late 18th and 19th centuries to alleviate overcrowding and sanitation issues. The ossuary is carefully arranged, often in decorative patterns, with skulls and tibias forming patterns along the walls.
While the bones are predominantly human, the Catacombs also contain a small number of artifacts and remnants from the quarries and the transportation process. These include fragments of tools, equipment, and even some personal items that were inadvertently interred along with the skeletal remains. The primary focus, however, remains on the sheer volume of human remains, a poignant reminder of the city’s history and past challenges.
