 In 1248, inspired by a visit on Sainte-Chapelle on a trip to Paris, bishop Hugues de la Tour decided to launch work on a new cathedral.Constructing a church in the prestigious Northern Gothic style would thus allow him to assert his supremacy over a city that had been put back into its bishop's power (rather than that of the counts of Auvergne) just some decades earlier.Notre-Dame-du-Port, that had inspired the cathedral of Stephen II, would thus again be surpassed.
