Part of the lower portion of the nave of Évreux Cathedral dates from the 11th century; the west facade with its two ungainly towers is, for the most part, the work of the late Renaissance, and various styles of the intervening period are represented in the rest of the church. A thorough restoration was completed in 1896. The elaborate north transept and portal are in the flamboyant Gothic. The choir, the finest part of the interior, is in an earlier Gothic style. Cardinal de la Balue, bishop of Évreux in the latter half of the 15th century, constructed the octagonal central tower, with its elegant spire; to him is also due the Lady chapel, which is remarkable for its finely preserved stained glass. Two rose windows in the transepts and the carved wooden screens of the side chapels are masterpieces of 16th-century workmanship.
