Built from the 13C to the early 16C, the cathedral was partly destroyed in 1586 by the Protestants. In recognition of the town's support, Henry IV undertook its reconstruction in a composite Gothic style. There is a lovely three-porch façade with rose windows and giant statues of the four evangelists. Splendid woodwork from 1706 decorates the chancel. There is a lovely marble Virgin by Michel Bourdin. In the crypt are vestiges of earlier buildings and the treasury.
