The D982 leading west from Rouen is the start of the Route des Abbayes, which meanders through woodland and meadows around the medieval Norman abbeys ' most of them enjoying their heyday under William the Conqueror ' at Saint-Martin-de-Boscherville, Jumiyges, Saint-Wandrille, Le Bec-Hellouin, and Caen, culminating in their masterpiece, Mont-Saint-Michel.
