Beneath the bustling streets of Paris lies a hidden world of darkness and history—the infamous Catacombs of Paris. This vast underground ossuary holds the remains of over six million people, creating an eerie yet fascinating labyrinth that attracts adventurers, historians, and curious travelers alike.
In this article, we’ll take you on a full tour of the Catacombs of Paris, uncovering their dark history, what to expect when visiting, and the chilling secrets buried within these ancient tunnels.
The History of the Catacombs of Paris
The Catacombs were born out of necessity. By the late 18th century, Paris’s cemeteries were overflowing, leading to unsanitary conditions and even collapsing graves. The solution? Transfer the bones of the dead into the city’s abandoned limestone quarries.
1786: The first bones were moved from the Les Innocents cemetery into the underground tunnels.
1810: The ossuary was officially organized, with bones arranged in macabre patterns.
1874: The Catacombs were opened to the public, becoming one of Paris’s most unusual attractions.
Today, only a small section (about 1.5 km) is open to tourists, while the rest remains off-limits—though urban explorers sometimes venture illegally into the deeper, uncharted tunnels.
