The first references to hermit settlements in these lands date back to the Suevian period, although it would not be until the 12th and 13th centuries that this Romanesque-style church was built, as part of a monastery that no longer exists. In later periods various reform works were carried out, and today the temple has been restored and consolidated.
This church dedicated to Saint Stephen of Atán has a single nave with a gabled roof. Its rectangular apse is topped by a barrel vault. Inscriptions and marks are visible in different parts of the walls, presumably made by the stonemasons who worked on its construction. The west door, which is larger than the north door, is made up of three pairs of columns that support slightly pointed archivolts over a plain tympanum. Other elements of interest include the decoration of the eaves and the three windows of primitive design located in the access arch to the apse (one) and the walls of the rectory (the other two).
