Catacombs of Paris

About Catacombs of Paris

The Catacombs of Paris are an underground network of tunnels beneath the city's streets, holding the remains of some six million people. The bones were moved here from the late 18th century onward, when Paris's overcrowded cemeteries became a public-health problem and the authorities began transferring remains into former limestone quarries that already honeycombed the ground beneath the city. What started as a practical storage solution was later arranged into the walls of stacked skulls and femurs that the site is now known for, with the bones set out in deliberate patterns rather than simply piled.

The visit route is a fair walk. You descend a tight spiral staircase, pass through a stretch of plain quarry tunnels, and then reach the ossuary itself, marked by the carved warning above the entrance that translates to "Stop, this is the empire of death." It stays cool underground all year regardless of the weather above, so a light layer is sensible even in summer. The path is narrow, uneven in places, and not suited to anyone who struggles with stairs or confined spaces, and large bags are generally not allowed.

The entrance sits at Place Denfert-Rochereau in the 14th arrondissement, and the exit brings you out on a different street a short walk away, so you don't return to where you started. This is one of the most popular sites in Paris and entry is capped for conservation and safety reasons, which means walk-up queues can be long and timed-entry tickets sell out ahead. Booking a dated, timed slot in advance is the reliable way in, especially in the warmer months.
