Underneath the busy streets of Paris are over 400 miles of tunnels. Many of these contain the bones & remains of millions of Parisians moved from overcrowded cemeteries in the late 1700's. Their skeletons, long since dis-interred from the churchyard graves their survivors left them in, are neatly stacked and aligned to form the walls of nearly one kilometer of walking passage.
