The north tower is the only one finished and is the taller of the two. It was given an elaborate Flamboyant Gothic decoration including a profusion of ornamental pinnacles and crockets, as well as copies of 13th-century statues installed in the niches. At the top is a lantern crowned by a large bronze pelican. The original 16th-century pelican statue is kept inside the Cathedral. This tower contains the six bells of the cathedral, which replaced those melted down during the Revolution. They date to the 19th and 20th century. The largest is the bourdon, Guillaume-Etienne of Gros Guillaume, 2.13 meters in diameter and weighing 6.08 tons. It was cast in 1841–42.
