The new church was exceptionally large, just ten meters shorter than the present cathedral, and just ten meters narrower on its west front. The west front was also exceptional because it was flanked by two towers, the "harmonic" style which became common in Gothic cathedrals during the following century. The chevet, or east end, probably also had a tower, and was flanked by two chapels. The transept of the cathedral was 55 meters long, the same length as the nave and choir. The nave and choir were composed of three vessels, each with two traverses. The central vessel was higher than the two collaterals.
