Rouen, capital of the northern French region of Normandy, is a port city on the river Seine. Important in the Roman era and Middle Ages, it has Gothic churches, such as Saint-Maclou and Saint-Ouen, and a cobblestoned pedestrian center with medieval half-timbered houses. The skyline is dominated by the spires of Cathédrale Notre-Dame, much-painted by Impressionist Claude Monet.
The Seine is a 777-kilometre-long river and an important commercial waterway within the Paris Basin in the north of France. It rises at Source-Seine, 30 kilometres northwest of Dijon in northeastern France in the Langres plateau, flowing through Paris and into the English Channel at Le Havre. Wikipedia
