The sandstone is a soft rock found throughout the Lower Dauphiné, where it is often the only building stone. This underground quarry is one of the major mining sites in the Drôme.Exploitées since ancient times, these quarries supplied the materials to major projects such as the medieval cathedral of Valencia College Saint-Barnard de Romans. Still used for the construction of the Canal de la Bourne in 1877, molasses is used less and less irreversibly from that time, mainly because of competition from cement.

The great dome of the Opera Garnier, home to several dance halls, each with its own piano. The most prestigious occupies the entire area under the green dome. The floor of the ballroom is inclined to replicate that of the theater. A sloping floor allows the public to see the choreography. For some shows, you need a flat surface. It then adds a platform.
