The former collegiate church, with its very pure Romanesque architecture, is striking for its richly sculpted decoration. The tympanum above the portal is decorated in oriental style while the modillions on the cornice and the capitals on the south window of the apse are adorned with a variety of bold and somewhat daring figures. On the inside, the elaborate sculptures on the capitals and the consoles of the transverse arch depict motifs of a rare elegance.
