Among the paintings on woo, note the retables of St Peter (14C) , St Martin (15C) and the precious reliquary carved by the Catalan Moragues in the 14C which once contained precious relics.

Interesting for its fine Romanesque gable and 12C portal. The 13C murals in the apse have unfortunately been altered.

Inside, there is a 15C retable , the 15C chapel of relics in place of the early Romanesque apse, and a Gothic painted retable dedicated to St Michael. The collegiate was built in the Romanesque period to house holy relics.
