The church contains a polychrome wood sculpture of the sixteenth century, representing the «flight to Egypt» and very well preserved. It also houses since 1868 the relics of Saint Irene discovered in Rome in 1825. In 1906, the master glassmaker Jules Mauméjean of Biarritz made glass. The protections put in place after the fire of the collegiate church, do not prevent to admire the unique sculpture of the «flight in Egypt», made of wood.
