Maurienne valley

Maurienne is one of the provinces of Savoy, corresponding to the arrondissement of Saint-Jean-de-Maurienne in France. It is also the original name of the capital of the province, now Saint-Jean-de-Maurienne.

The Maurienne valley is one of the great transverse valleys of the Alps. The river which has shaped the valley since the last glaciation is the Arc. The valley begins at the village of Écot (in the commune of Bonneval-sur-Arc), at the foot of the Col de l'Iseran, and ends at the confluence of the Arc and the Isère in the commune of Aiton. The mountains on the southern side are the Dauphiné Alps and the Cottian Alps. On the northern side are the part of the Graian Alps known as the Vanoise. The capital, Saint-Jean-de-Maurienne, lies at the confluence of the Arc and the Arvan River.

Part of the main road and rail route between Lyon and Turin runs through the valley. The A43 autoroute and a railway line enter at the western end from the Isère valley, and leave at Modane using the Fréjus Road and Rail Tunnels respectively which both emerge at Bardonecchia in Italy.
