Paris, the capital of France, is often called La Ville Lumière (meaning ‘The City of Light’), however, beneath this bustling European city of 12 million people, lies a dark subterranean world holding the remains of 6 million of its former inhabitants. These are the Paris Catacombs: a network of old caves, quarries and tunnels stretching hundreds of miles, and seemingly lined with the bones of the dead.
