Eglise Notre-Dame de Pontorson

Built in the 11th century on the initiative of William the Conqueror by the same builders as the Abbey of Mont Saint-Michel, the church of Notre-Dame is of Romanesque style and Gothic transition. A stained glass window in the choir indicates its raison d'être: the happy passage of the Couesnon by the men of William the Conqueror, in danger of getting bogged down.
