The Real Catacombs!  

The Catacombs of Paris is a famous burial place in Paris, France. It is a network of subterranean tunnels and rooms located in what were Roman-era limestone quarries. The quarries were converted into a mass tomb near the end of the 18th century. It is most widely known as "the catacombs", but the official title is "les carrières de Paris" or "the quarries of Paris."

The use of the depleted quarries for the storage of bones was established in 1786. At the time, the Les Halles district in the middle of the city was suffering from disease, due to contamination caused by improper burials and mass graves in churchyard cemeteries, especially the large Cimetière des Innocents. It was decided to discreetly remove the bones and place them in the abandoned quarries.

Remains from the cemetery of Saint-Nicolas-des-Champs were among the first to be moved. Bodies of the dead from the riots in the Place de Greve, the Hotel de Brienne, and Rue Meslee were put in the catacombs on August 28 and 29, 1788.

Now that's a lot of bodies!!
