 The cathedral is in the Gothic, Renaissance and Romanesque architectural styles.The construction of the church began in 1273 and finished only in 1888, when the nave was connected to the belfry, a fine, partly octagonal, bell tower.It is noted for its Renaissance rood screen with reliefs of the labors of Hercules, built in 1534 and moved to the western end of the nave during the revolution, and for the tomb of the bishop Jean de Langeac (who commissioned the rood screen) on which are carved scenes of the Apocalypse, inspired by Dürer.
