Cathédrale Notre-Dame de Rouen

It took several centuries to build the Cathedral, and it is in itself a display of each successive stages in the development of the Gothic style. The Tour Saint-Romain (12th century) ; the Portail des Libraires and the Portail de la Calende (14th century) ; the West façade and Tour de Beurre (15th and 16th centuries) ; the cast iron spire (152 metres high - 19th century). Beautiful stained glass windows.
