This cathedral is a magnificent Gothic building built on the ruins of the old cathedral. The majestic facade is even more beautiful since its restoration. The interior of the cathedral is quite unusual and particularly impressive. The whiteness of the limestone tufa, the imposing size of the nave, a 103 meters long and 37.5 meters high, it has an effect of power, strength and grace. And you can admire the tombs of Francisco II and Marguerite de Foix (parents of Anne of Brittany) at the beginning of the sixteenth century.
