The old quarries

Geological formations…
The subsoil in the Île-de-France region is teeming with useful materials. Limestone is used in building; gypsum is used to make plaster; chalk goes into lime, cement and Paris white; and marl-limestone enriches the soil.
Here in Champagne-sur-Oise, the geological formations are essentially from the Tertiary period – 65 million to 2.6 million years ago – from the lower Bartonian, Auversian and upper Lutetia ages. The layers consist of limestone, marl, sand and silt.
…and resource-rich quarries
How the stone was cut and the architectural styles used depended on the quarry, the hardness of the stone and what the masonry was used for. Historically, both open-air and underground quarrying took place at Champagne-sur-Oise. Underground quarrying was initially kept away from built-up areas, but then moved to the outskirts of towns to make transportation to construction sites easier.
Champagne-sur-Oise exploited the riches of its subsoil by extracting limestone from three large underground quarries. The cut stone and quarry stone from here were mainly used to build houses.
