The catacombs of Paris are in the former Denfert-Rochereau quarry. They come from Roman times. They form an approximately 50-kilometer network of tunnels, in which the dead were transferred from various Parisian cemeteries in the 19th century. In the Catacombs, a 2 km tourist route has been led.
In the nineteenth century, due to the overpopulation of Paris and the lack of space at local cemeteries, it was ordered to move the corpses from cemeteries in the Les Halles district to the Roman catacombs in the Denfert-Rochereau quarries. From the beginning they have become a frequently visited place, especially by enthusiasts of "strong impressions". Victor Hugo, among others, often visited here, who described them in "Misery".
An illuminated tourist trail has been led throughout the Catacombs. It leads, among others, through the Crypt of the Passion or the Gilbert's Tomb. The walls of the catacombs are covered with human bones and skulls arranged in heaps.
