Built over a period of five centuries (13C-17C), this eclectic cathedral combines the respective Gothic styles of northern and southern France. Inside, the nave and chancel are not quite aligned. Note the rich array of stained-glass windows, including one dedicated to the King of France (15C), which reproduces the features of Charles VII and the dauphin, the future King Louis XI. The high altar, stalls, organ case and five large bay windows in the apse date from the 17C.
