A very enigmatic church with a slender Gothic cathedral choir.
Inside, the whiteness of the chiselled stone and the brightness of the high lancet windows contrast with the dark 18th century woodwork in the nave.
The altarpiece in polychrome carved wood (14th century) telling the story of the life of Saint Thibault, the richness of the decoration of the north portal and the preciousness of the Saint-Gilles chapel, which houses the shrine of Saint Thibault, are also remarkable.
