Catacombs of Paris

The Paris Catacombs (Catacombes de Paris) comprise an expansive underground labyrinth of historic limestone quarries and ossuaries spanning roughly 20 meters beneath the central and southern districts of Paris. Extending across more than 280 to 300 kilometers of abandoned subterranean galleries, a fortified section houses the skeletal remains of over six million people, forming the largest collective necropolis in the world.
