Dome

Detail, Apostles Window; With the exception of the Romanesque lancets of the west facade and the window of Notre-Dame de la Belle Verrière reset in the south choir, most of the glazing of the 176 windows was accomplished between ca. 1200 and ca. 1235. Restorations have been carried out intermittently since the 14th century, with important campaigns in the 19th and 20th centuries, including that undertaken by Nicolas Coffetier, with the assistance of Louis-Charles-Auguste Steinheil, from 1868.
