The monastery, that once existed here may have been founded by Benedictine monks. In later days Augustine canons lived here, before the church became a parish church. Due to an inscription, found during restauration works, it is clear, that 1180 this church existed already, though smaller than it is today, as it got enlarged at least twice. First time within the 13th century.

The complete western front is probably from the first construction phase of the church. There are strong parallels to Paço de Sousa (previous uploads), only about 20kms west.

The side portal of the church is carved even more skilful. Here a bull and a lion flank the door.
