Quarries of Herblay are over 14km wide and some hundreds of meters deep, on hillsides along the Seine.

In 1776, the exploitation of new underground quarries in Paris was forbidden. People had to take the stone elsewhere. It is for this reason that the quarry was known as "Imperial quarry" or "Quarry of the city of Paris". They built many monuments in Paris with this stone because it was high quality (the famous Royal stone).

Among the monuments built, there was The Pantheon of Paris, Department of Marine Place de la Concorde, the Gare de l'Est, the mint as well as many statues at Versailles.

The network's quarries has been excessively exploited in Herblay. The ceiling is fragile and the walls separating the tunnels are very thin. To reinforce the quarry, they have added many pillars and reinforcement structures.

Later, like many underground quarries, they served to mushroom plantation in the 1980s. The workers have dug additional corridors between small quarries networks.

A few years later and they were gradually abandoned. The latest mushroom plantation closed in 1995.

Since 2003, the association "Herblay heritage" has undertaken to make public visits to the part of the "English entry" with the famous double-arched vault and pretty ponds.

Quarries of Paris - Showroom mineralogy of the Rue Saint Jacques.

The showroom mineralogical most famous of Paris is the Salle Saint-Jacques. It was constructed by Major Gambier in the heart of the underground quarry system of the GRS (Great South network), just false catacombs at Denfert-Rochereau, in fact ossuaries in old underground quarries.

The side benches were used to display the site's geological curiosities. At the center of the room, a staircase dummy materialized superposition of limestone beds of the place. Each step was a sample. Originally, the name of each geological layer of rock was inscribed on the front steps of each room but this was very bumpy because too many visitors have visited illegal.

Can be found in certain geological showroom more difficult to access such information.

Quarries of Saint-Cloud, in the Trocadero Park

The underground quarries of Saint-Cloud (of coarse limestone) are used as building stone. The grand facade of the Colonnade of the Louvre is partly made with this stone. The rest comes from the underground quarry of Saint-Leu Esserent. It also used the stone to build the castle of Saint-Cloud, located a few tens of meters from the quarry.

The walls of building quarry were partially dismantled to get new stones. They were used to renovate the castle of Saint-Cloud in the 19th century. However, the consequences of a large fire, the foundations were razed. The stones stolen are become useless.
