Church of San Andrés
The Church of San Andrés dominates the Valley of Cayón from a high point north of the Range of Caballar. It was built in the first half of 12th century and for a good part of its history it had a land around it as the abbey grounds.
It has one nave, ending in a semicircular apse divided in three bodies separated by adorned columns with decorated spires. The north and south walls, as well as in the apse, stand out the cantilevers of varied forms, especially those of animal. Above them is a decorative cornice.
The entrance, with a rounded arch, has four carved archivolts and varied spires. Above the doorway is the tower, whose first floor is of late Romanesque era and the rest dates from 16th and 17th centuries. The apse is covered with semi-dome vaults and there is a long presbytery with half barrel vaults.
In an annexed room is kept a collection of Medieval sarcophagus, eighteen in total, dating from between 10th and 13th centuries.
It is regarded as of Good Cultural Interest since 1982.
