The Church of San Juan de Amandi originated in Pre-Romanesque times, according to documentary evidence, but stylistically corresponds to the Baroque phase of the Asturian Romanesque, with elements of a Gothic nature.
It has a single nave with a semi-circular apse. Two compartments have been added to the north and south sides, in addition to a semi-circular portico with Tuscan columns that surround the church. Above this 17th-century portico stands a Baroque bell gable with two bays, dating from the 18th century.
Outside the building, there are two portals: one in the richly decorated façade, with a pointed arch and strongly flared, and a simply decorated portal on the south side, with a semi-circular arch.
The body of the nave is topped with corbels. The semi-circular apse is decorated with four semi-embedded columns topped with capitals; a chequered impost runs horizontally around the apse.
Inside, the east end is separated from the nave by a semi-circular triumphal arch resting on decorated columns and capitals.
The apse is divided into two sections, separated by another semi-circular serrated arch. The most significant feature comprises the double arches decorating the entire east end.
