This is in front of an early 11th century building. It is an example of Lombard Romanesque as you can see in the blind arches that crown the drum of the apse; in this case they rest on rusty corbels where with imagination some face can be identified. The apse has a double-slit window with a semicircular arch made of small stones. In 1879, the west door was opened, which preserves the doors with the old tools, and the Romanesque door at noon was canceled, which today is only visible from the inside and has been converted into a baptismal chapel.

On the north façade we find the bell tower that carries on a chamber that is an appendix of the nave of the church, whose function has been speculated to be a primitive sacristy or a storehouse of tithes. The bell tower, made of good granite ashlars, has three different bodies, the lower two are from the 13th century and the upper one was rebuilt in 1939.
