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

1.5km for 150m of elevation gain. As soon as you leave the Col de Parménie, the gradient starts at 12%, then quickly increases to 14% and then climbs to 17%. It calms down a bit after the bend. The road is in good condition, relatively wide, and with little traffic (it's a dead end), which allows you to maneuver to cope with the slope.
