 The church's name is sometimes anglicized as St Owen's.Built on a similar scale to nearby Rouen Cathedral, the abbey is famous for both its architecture and its large, unaltered Cavaillé-Coll organ, which was described by Charles-Marie Widor as "a Michelangelo of an organ".With the cathedral and the Church of Saint-Maclou, Saint-Ouen is one of the principal French Gothic monuments of the city.
