Catacombs of Paris

The site is an extensive underground ossuary housed within former quarries, holding the remains of approximately six million individuals transferred for public health reasons. Created in the late 18th century and opened officially in 1809, it combines historical significance with archaeological value. The ossuary includes a network of tunnels and galleries with arranged bones, alongside museum-like exhibitions that document its history and the city's past.

As a cultural heritage site, it offers a unique blend of an archaeological site and a museum, illustrating the city's approach to managing burial space in earlier centuries. Its exhibitions and bone arrangements provide insight into Parisian history and underground quarry systems. The site is accessible to the public with paid admission and is located beneath the city, making it a notable example of subterranean historical preservation.
