Grésivaudan

The Grésivaudan (French pronunciation: [ɡʁezivodɑ̃]; sometimes Graisivaudan) is a valley of the French Alps, situated mostly in the Isère. Etymologically, Graisivaudan comes from roots meaning "Grenoble" (Gratianopolis) and "valley".^[1] It comprises the alluvial plain of the river Isère from Grenoble to the confluence of the Arc; or, more recently, the entire valley of the Isère from Tullins to Albertville. The stretch from Tullins to Grenoble is now the Bas-Grésivaudan (Lower Grésivaudan) and that between Grenoble and Albertville is the Haut-Grésivaudan (Upper Grésivaudan).
