The Catacombs of Paris are a tourist and cultural site located under the city of Paris, France. They house the remains of more than six million people who were exhumed from the city's cemeteries during the 18th and 19th centuries.

The Catacombs are managed by the City of Paris, which owns them. The site is divided into two parts: the part open to the public, which extends over about 2 kilometers, and the part closed to the public, which extends over about 30 kilometers.

The part open to the public is accessible to the public for a fee. Visits are guided and last about an hour. Visitors can see the remains of the people buried in the catacombs, as well as exhibitions on the history and culture of the catacombs.

The part closed to the public is only accessible to experts and researchers. This part of the catacombs is made up of complex galleries and tunnels, which are still being explored.

The Catacombs of Paris are organized by a staff of guides, guards, and technicians. The guides are responsible for accompanying visitors during the tours. The guards are responsible for the security of the site. The technicians are responsible for the maintenance of the site.
