The underground ossuaries in Paris, France, hold the remains of more than six million people. Located south of the former city gate "Barrière d’Enfer" (Gate of Hell) the catacombs were created when Paris had a series of cave-ins and overflowing cemeteries. The human remains were transferred from cemeteries to the reinforced tunnels.
This is a small section of stone from the walls of the Catacombes de Paris, sealed in a glass vial with a tombstone grey cord.
