The stained glass windows of the north aisle are almost all modern, and in imitation of the style of the thirteenth century. Those of the south aisle belong to the fifteenth and sixteenth centuries, except the ninth window nearest the transept, which dates from the thirteenth century. Our illustration give an idea of the simple yet skilful composition of these little masterpieces, but cannot reproduce the beauty of their colouring.

The third and fourth are devoted to Christ; the fifth to the life and stoning of Saint Stephen; the sixth to the Virgin, and different saints and donors; the seventh to the life of Christ; the eighth to the life and miracles of Christ; the ninth to the baptism of Christ and to various saints. All this stained glass has been removed and put into a place of safety for the duration of the war.

In the eleventh century it possessed no transept, but included a semi-circular apse flanked by two towers, on the site of which rise the two present ones (_see p. 205_), which date from the twelfth century and recall those of the cathedral. There remains of the twelfth century Romanesque church, besides almost the whole of the transept, the south door under the porch, the pillars and the aisles of the nave, as well as the ground floor of the west front. In 1157 Notre-Dame collapsed, and was partly reconstructed. The apse was rebuilt with three radial chapels. In the nave and choir the round arches of the tribunes and arcades were replaced by pointed ones: the walls were raised in height and pierced by windows, below which was established a triforium (photo below). Gothic vaulting in the nave and transept replaced the wooden roof. The two storeys and the pinnacle of the west front, between the towers, belong also to this period.
