Susa Valley

The Susa Valley (Italian: Val di Susa, French: Val de Suse, Occitan: Val d'Ors) is a valley in the Piedmont region of northern Italy, located between the Graian Alps in the north and the Cottian Alps in the south. It is the longest valley in Italy. It extends over 50 km (31 mi) in an east-west direction from the French border to the outskirts of Turin. The valley takes its name from the city of Susa which lies in the valley. The Dora Riparia river, a tributary of the Po, flows through the valley.

A motorway runs through the valley from Turin to Chambéry in France, over the Col du Mont Cenis or through the Fréjus tunnel, and to Briançon, also in France, over the Col de Montgenèvre.

Among the notable peaks that surround the valley are:


During the Roman age, Augustus formed an alliance with the Segusini of Cottii Regnum to link Italy and France by building a road through the Valley and over the Col de Montgenevre. During the Middle Ages, the road was called Via Francigena, and pilgrims passed through Mont Cenis and the Susa Valley on their way to Rome. It was one of the most used Alpine passes from the Middle Ages to the Nineteenth Century. Several abbeys were built to accommodate pilgrims, such as Novalesa Abbey founded in 726AD on the foot of a mountain and the monumental Sacra di San Michele abbey.

Protesters have fought a 10-year battle to prevent a 57 km (35 mi) rail tunnel being built through the valley.[1]
