Beneath the cobblestone streets, the cafés, and the lights of Paris lies a dark secret: hundreds of miles of tunnels lined with the remains of more than six million people. The Paris Catacombs are one of the city’s most unsettling attractions, a place where human skulls are stacked into sculptures and walls bear warnings that death is coming for visitors too. But according to countless visitors and tour guides, the catacombs are not just a resting place for the dead—they are haunted.

How the Catacombs Came to Be

The story begins in 52 BCE, when Roman soldiers arrived on the swampy banks of the Seine and conquered the local Parisii tribe. The Romans built a fort and named the settlement Lutetia, from the Latin word for mud.

Show Notes

Beneath the streets of Paris lies a labyrinth packed with the bones of more than six million people—relocated centuries ago when the city's cemeteries overflowed. Today, visitors descend into the darkness and come back with stories: disembodied whispers, footsteps in empty passages, the feeling of being watched. Some are convinced the restless dead never left. Others say the mind simply unravels in the silence. But one question lingers in those tunnels: are the catacombs truly haunted… or is it the living who can't be trusted down there?
