Located in the municipality of Montederramo, this temple was possibly founded in the tenth century in a different place than it occupies today, in the place of Seoane Vello. It belonged to the Order of St. Benedict and later to the Cistercian Order. Until the disentailment of Mendizabal, this temple enjoyed an important economic and social power. Since 1951 it has been considered an Asset of Cultural Interest.
The facade of the church, completed in 1607, is an example of the Herrerian style in Galicia.
The founding document of the Mosteiro de Santa María de Montederramo, granted in Allariz on 21 August 1124 by Teresa of Portugal: ‘locum qui dicitur Rouoyra Sacrata, qui est in Monte de Ramo, territorio Caldelas’ (the place called Rovoyra Sacra which is in Montederramo, territory of Caldelas) is the first written document in which the Ribeira Sacra is mentioned.
