1. Farther along, ther are two chapels that occupe the space where the old Abbatial palaces once stood. At the feet of the church are found: first, the penitential chapel, formerly dedicated to St. Matthias; in the central nave, there is an old baptismal font from the hamlet of Colsa, in the Cabuérniga valley; and, finally, at the left of the church door, a chapel founded by Antonio de Azoños Escobedo in 1671, whose Baroque altarpiece constains a good copy of Raphael's Visitation.

Dann gibt es noch zwei Kapellen, die den Raum der alten äbtlichen Paläste einnehmen.Die erste ist die Bußkapelle, früher de des Heiligen Matías.
