Notre-Dame Cathedral
The cathedral’s high tower dominates the canons’ quarter. Past the immense portal of the Last Judgement, under the vaults of the nave, you’ll get the full measure of this gigantic Gothic stone vessel, collegiate church then cathedral since the 16th century. An astrolabe clock, a Cavaillé-Coll organ, a Descente de Croix by Rubens and so many other treasures: this is a museum in its own right.
