Interior view of the chapel.

This small Gothic chapel from the 13th century stands next to the "Silo of Charlemagne" and is a simple rectangular building with two sections which include an upright chevet and a simple groin vault. Simple cylindrical base columns serve as a support for the roof.

The exterior is also very simple, with walls of irregular ashlar stones, no buttresses, and a pointed arched doorway with a crismon (sacred monogram).

Used as a parish church up until the 18th century, this small chapel was left without worshippers for a long period of time until it was restored by Florencio Ansoleaga in the 20th century, opening up the small ox-eye above the door and adding the pilgrim's bell.
