Rouen (; ) is a city on the River
Seine in the north of France. It is the capital of the
region of
Normandy. One of the largest and most prosperous cities of
medieval Europe, it was the seat of the
Exchequer of
Normandy in the Middle Ages. It was one of the capitals of the
Anglo-Norman dynasties, which ruled both England and large parts of modern France from the 11th to the 15th centuries. It was here that
Joan of Arc was executed in 1431. People from Rouen are called
Rouennais.
