From 1785 the bones of Paris’s overcrowded cemeteries were moved into former limestone quarries south of the old city. The site was consecrated as the Paris Municipal Ossuary in 1786 and has received visitors since 1809.

This page collects what we have published on the Catacombs. Figures for the number of people buried there are estimates; the official history gives none.
