Rouen. Rouen is a city on the River Seine in the north of France. It is the capital of the region of Normandy. Formerly one of the largest and most prosperous cities of medieval Europe, Rouen was the seat of the Exchequer of Normandy during 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. The population of the metropolitan area at the 2011 census was 655,013, with the city proper having an estimated population of 111,557. People from Rouen are known as Rouennais. Rouen and its metropolitan area of 70 suburban communes form the Métropole Rouen Normandie, with 494,382 inhabitants at the 2010 census. In descending order of population, the largest of these suburbs are Sotteville-lès-Rouen, Saint-Étienne-du-Rouvray, Le Grand-Quevilly, Le Petit-Quevilly, and Mont-Saint-Aignan, each with a population exceeding 20,000. Rouen was founded by the Gaulish tribe of the Veliocasses, who controlled a large area in the lower Seine valley. They called it Ratumacos; the Romans called it Rotomagus. It was considered the second city of Gallia Lugdunensis after Lugdunum itself. Under the reorganization of Diocletian, Rouen was the chief city of the divided province Gallia Lugdunensis II and reached the apogee of its Roman development, with an amphitheatre and thermae of which foundations remain. In the 5th century, it became the seat of a bishopric and later a capital of Merovingian Neustria. From their first incursion into the lower valley of the Seine in 841, the Normans overran Rouen. From 912, Rouen was the capital of the Duchy of Normandy and residence of the local dukes, until William the Conqueror moved his residence to Caen. In 1150, Rouen received its founding charter which permitted self-government. During the 12th century, Rouen was the site of a yeshiva known as La Maison Sublime. Discovered in 1976, it is now a museum. At that time, about 6,000 Jews lived in the town, comprising about 20% of the population. On 24 June 1204 King Philip II Augustus of France entered Rouen and definitively annexed Normandy to the French Kingdom. He demolished the Norman castle and replaced it with his own, the Château Bouvreuil, built on the site of the Gallo-Roman amphitheatre. A textile industry developed based on wool imported from England, for which the cities of Flanders and Brabant were constantly competitors, and finding its market in the Champagne fairs. Rouen also depended for its prosperity on the river traffic of the Seine, on which it enjoyed a monopoly that reached as far upstream as Paris. In the 14th century urban strife threatened the city: in 1291, the mayor was assassinated and noble residences in the city were pillaged. Philip IV reimposed order and suppressed the city's charter and the lucrative monopoly on river traffic, but he was quite willing to allow the Rouennais to repurchase their old liberties in 1294. In 1306, he decided to expel the Jewish community of Rouen, then numbering some five or six thousands. In 1389, another urban revolt of the underclass occurred, the Harelle. It was suppressed with the withdrawal of Rouen's charter and river-traffic privileges once more. During the Hundred Years' War, on 19 January 1419, Rouen surrendered to Henry V of England, who annexed Normandy once again to the Plantagenet domains. But Rouen did not go quietly: Alain Blanchard hung English prisoners from the walls, for which he was summarily executed; Canon and Vicar General of Rouen Robert de Livet became a hero for excommunicating the English king, resulting in de Livet's imprisonment for five years in England. Joan of Arc was burned at the stake in Rouen on 30 May 1431 in this city, where most inhabitants supported the duke of Burgundy, Joan of Arc's king enemy. The king of France Charles VII recaptured the town in 1449. During the German occupation, the Kriegsmarine had its headquarters located in a chateau on what is now the Rouen Business School. The city was heavily damaged during World War II on D-day and its famed cathedral was almost destroyed by Allied bombs. Rouen is known for its Rouen Cathedral, with its Tour de Beurre financed by the sale of indulgences for the consumption of butter during Lent. The cathedral's gothic façade was the subject of a series of paintings by Claude Monet, some of which are exhibited in the Musée d'Orsay in Paris. The Gros Horloge is an astronomical clock dating back to the 14th century.
