The Crypt The Catacombs Beneath Paris Here, in dark tunnels twisting deep beneath the city, rest the bones of some six million Parisians who died between the 7th and 19th centuries. Engraved on a plaque adjacent to a pile of bones appear the words, A la mort, on laisse tout. " One abandons everything to death." (A medieval microbe fighter in beaked mask and long robe welcomes visitors and begins to speak . . .)
