This delightful town along the Seine is centered around its historic main square. Key architectural sights include the 15th-century Church of Notre Dame, built in the flamboyant Gothic style, and the 13th-century Maison des Templiers (House of the Knights Templar), which now houses a museum. Not far are the haunting romantic ruins of the 7th-century Abbey de Jumièges, founded in 654 during the conversion of the region to Christianity. Destroyed by Viking raiders, the abbey was later restored in the 11th century by Viking descendants who settled the area.
