Skip the long lines and unlock gates to hidden rooms in the Catacombs on this small-group tour. Explore the world’s largest ossuary and discover the buried secrets of underground Paris.

Beneath the streets of Paris, there is another, darker side to the city that few get to see. Twenty meters below street level, the galleries of the Paris Catacombs extend for over 200 miles - a subterranean maze under the city that many are unaware of as they stroll along the streets above.

Initially quarried to provide limestone for the construction of the famous Parisian buildings and bridges, the Paris Catacombs are now home to the bones of more than 6 million former Parisians. Their remains were carefully moved here in the 18th century, in a discreet operation to transfer them from the insalubrious and overflowing cemeteries of the city center. Nowadays, wall after wall of stacked bones, and some more slightly macabre compositions, await you as you follow an expert local guide into ‘The Empire of Death'.

Your guide will lead you through the underground passages. You'll access to parts of the Catacombs that are closed to the general public, have underground gates unlocked especially for you and your group, and learn the intriguing stories of those who worked, visited and have been laid to rest here over the centuries, including the secret societies who still visit today.
