This 13C-14C cathedral stands on a very pretty square surrounded by 16C-17C arcaded houses. Despite the differences in style of its three floors (13C, 16C and 18C), the façade has retained its harmony. The central portal is dedicated to the Last Judgement and the story of John the Baptist, and the side portals to the Virgin Mary and St Peter. Inside, the perspective created by the long, narrow nave is particularly striking.
