Les Andelys (pop. 9,047) lies in the Seine valley, here enclosed by high chalk cliffs, with the imposing ruins of Château Gaillard looming over the town. The castle was built by Richard Coeur- de-Lion in 1197 to bar the French king's access to Rouen. In spite of its strength, however, it was taken by the French in 1204. The outer walls have
almost completely disappeared, but much of the keep with its surrounding walls has survived. There are two churches in the town, the more notable of which is Notre-Dame, with a 13th C. nave, a facade of the 16th-17th C., a notable organ and fine stained glass. The Musée Nicolas Poussin displays pictures by Poussin (1594-1665), who was born in the neighboring village of Villers. There is a fine view from the bridge over the Seine.
