Piedmont is surrounded on three sides by the Alps, including Monviso, where the Po rises, and Monte Rosa. It borders with France (Auvergne-Rhône-Alpes and Provence-Alpes-Côte d'Azur), Switzerland (Ticino and Valais) and the Italian regions of Lombardy, Liguria, Aosta Valley and for a very small part with Emilia Romagna.
