April 29, 2026, Canon obusier de Saint-Gervais

This cannon, cast in 1843 at the National Foundry of Saint-Gervais, was shipped to the island of Bourbon to ensure its defense. The Department of Réunion presented it to Mr. Vaudeville, Prefect of Isère, who handed it over to the Commune of Saint-Gervais on July 7, 1973. https://fr.wikipedia.org/wiki/Fonderie_royale_de_canons_de_Saint-Gervais

Traces of this castle can be found in the archives dating back to 1315, when it was under the jurisdiction of the lord of Saint Geoirs. A remarkably well-preserved tower still remains.

A beautiful cycle path that follows the Isère River. There are a few places to stop for a picnic, and there's even a water fountain. This is a good place to cycle during the summer months as it's generally cooler along the riverside, which is well shaded.
