Origin and history

The Royal Saint-Gervais cannon foundry, located in Isère, was created in 1678 by Jean-Baptiste Colbert and Samuel Dalliès de La Tour to produce iron cannons that were less expensive than bronze cannons. Located near the Isère, it used the ore from the Allevard mines and charcoal from the Ecouge forests. The first stone was laid in January 1679, marking the beginning of an intensive production for the navy of Louis XIV and then Louis XV after its acquisition in 1731.

In the 18th century, the foundry employed more than a hundred workers and supplied Toulon's arsenal, despite recurrent shortages of coal. Under the First Empire, it was modernized in 1805, reaching a monthly production of 30 cannons and 1,500 quintals of steel. The blast furnaces, powered by Drevenne's water, operated thanks to four hydraulic wheels, only one of which remains today.

The site reached its peak in the 19th century, with massive commands like 250 cannons in 1862. However, the advent of the striped cannon in 1873 made the establishment obsolete, resulting in its closure. Partially classified as historical monuments in 1986, then entirely in 2015, the foundry retains its Rovon stone buildings, its ovens, and its artificial pond. After 1912, the site was converted into a cardboard factory and then an industrial enterprise.

The architecture, unchanged since 1843, illustrates the industrial engineering of the period: a symmetrical rectangle bordering the Isère, with stone forebody, an exceptional wooden frame, and remnants of hydraulic infrastructure. The water-driven canal and catchment area, partially preserved, testify to its historic energy system.

The Saint-Gervais foundry embodies French metallurgical innovation, moving from iron cannons for Louis XIV to mass production under Napoleon. Its decline reflects the military technological evolution, while its conservation offers a rare example of an intact pre-industrial plant, now mixed property (private and communal).
