Gothic-style church built in the second half of the 14th century under the patronage of Fernán Pérez de Andrade, who rebuilt an earlier monastery dating from the 12th century. It was declared a National Monument in 1919 and later designated a Site of Cultural Interest (BIC). Inside, the main chapel features a relief depicting God enthroned and surrounded by the four Evangelists. Angels playing different instruments, one of them a bagpipe, appear on the ribs of the vault, along with capitals decorated with fantastic animals. Particularly noteworthy is the extensive collection of sarcophagi belonging to various members of the Andrade family. The tomb of Fernán Pérez de Andrade, considered a precursor of medieval funerary sculpture, originally stood in the main chapel next to that of his wife Doña Sancha, but was moved in 1782 to the foot of the church beneath the choir. The sarcophagus is raised above the ground on the Andrade family’s symbolic animals, a bear and a wild boar, with the family coat of arms at the head and foot, hunting scenes of wild boar along the sides, and the recumbent figure of Andrade portrayed in armor in a resting position.
