This stone has also been used for building in parts of the region, and still is today in the adjoining commune of Saint-Maximin. It was also used for building in Chantilly itself during the 18th century, when a quarry on the current site of the racecourse produced stone for the court officials' housing and the stables. In the following century the quarry was used to grow mushrooms, then as an air raid shelter during World War II. It now belongs to the Chantilly Estate and is periodically open to the public.
