Saint-Romain-le-Puy is a commune in the Loire department in central France.The town is located 8km from Montbrison along the D8. It was originally built on the volcanic peak (le puy), but has since migrated to the plain.Local industries include Mineral Waters (François Parot, a public works entrepreneur sunk a well in 1858) and Glassmaking (Saint-Gobain-Emballage factory founded in 1893). Agriculture includes beef rearing, dairying and wine-growing.Its inhabitants are known as Saint-Romanais.The commune is twinned with Monte San Biagio (Italy).GeographyLe Puy itself is of volcanic origin and the surrounding plain of Forez has basaltic conglomerates. Wells have been sunk to exploit the naturally sparkling mineral waters.HistoryLe Puy is located on the Roman road, the Bolène Way, linking Lyon (Lugdunum) to Bordeaux (Burdigala), which was constructed during the reign of the emperor Augustus, by his son-in-law Agrippa. It is also on the Gallo-Roman way from Sury to Changy. These roads were later reused by pilgrims to Santiago de Compostela.About 500, Carétène (aunt of Saint Clotilde the wife of Clovis) replaced a temple of Venus (famous for a bath of youth utilising the areas' mineral springs) by a Christian church dedicated to Saint Michael.
