A bridge mistreated by the Gardon river

The metal Richaldon Bridge, built at the end of the 19th century, served the mines. It has also experienced flood-related misfortunes. Mining profoundly shaped the economic activity of the Vallée Longue in the 19th and 20th centuries. The antimony mine was opened in the 18th century. It was in use throughout the 19th century and was complemented by a foundry in 1896. All activity at the site ceased in 1951. Lead was mined from 1860 to 1868. From the 19th century on, many farmers were also employed in the mines in La Grand'Combe, alternating mining with their work in the fields. This phenomenon persisted until the 1980s.
