Catacombs of Paris

catacomb (n.)

"underground burial place," usually catacombs, from Old English catacumbas, from Late Latin catacumbae (plural) "sepulchral vaults," originally the region of underground tombs between the 2nd and 3rd milestones of the Appian Way (where the bodies of apostles Paul and Peter, among others, were said to have been laid) near Rome; the word is of obscure origin, perhaps once a proper name, or dissimilation from Latin cata tumbas "at the graves," from cata- "among" + tumbas, accusative plural of tumba "tomb" (see tomb).
