This church of simple beauty was built between the 11th and 13th centuries as the temple of a convent of Benedictine nuns. In the 17th century some reforms were carried out, including the demolition of the left-hand side apse. In its place the Torrrenovais chapel was added, which houses the tomb of Rodrigo López de Quiroga. However, the place had been the site of a monastery for many centuries before, since the times of the Visigoths.
San Fiz de Cangas is of rectangular design with a single nave. Its main façade boasts a pointed arch with the tympanum situated below. The latter is decorated with a Greek cross, symbols of the sun and the moon, concentric rectangles and a star within a square. Inside, there are altarpieces dating back to the 18th and 19th centuries, in addition to the praying figure of Don Rodrigo López de Quiroga.
