(1163- 1350) Gothic cathedral on the Île de la Cité in Paris. Probably the most famous Gothic cathedral, Notre-Dame is a superb example of the Rayonnant style. Two massive Early Gothic towers (1210-50) crown the western facade, which is divided into three stories and has doors adorned with Early Gothic carvings and surmounted by a row of figures of Old Testament kings. The single-arch flying buttresses at the eastern end are notable for their boldness and grace. Its three great rose windows, which retain their 13th-century glass, are of awe-inspiring beauty
