In Paris' Roman era, its main cemetery was located to the outskirts of the Left Bank settlement, but this changed with the rise of Catholicism, where most every inner-city church had adjoining burial grounds for use by their parishes. With Paris' growth many of these, particularly the city's largest cemetery, <answer>les Innocents</answer>, were filled to overflowing, creating quite unsanitary conditions for the capital. When inner-city burials were condemned from 1786, the contents of all Paris' parish cemeteries were transferred to a renovated section of Paris' stone mines outside the "Porte d'Enfer" city gate, today place Denfert-Rochereau in the 14th arrondissement. The process of moving bones from Cimetière des Innocents to the catacombs took place between 1786 and 1814; part of the network of tunnels and remains can be visited today on the official tour of the catacombs.
