With Alfonso III dead and the kingdom of Asturias divided among his sons, Asturian pre-romanesque architecture entered its last stage. Consecrated on September 24, 921, it has the architectural and decorative reference of the model laid down by the Church of San Julián de los Prados.
In the 17th and 18th centuries, it underwent several reconstructions, altering especially the structures adjoining the vestibule, by communicating them with the side aisles.
In 1936, during the Spanish civil war, the original roof burned but it kept most of its sculptured decoration and original paintings.
