This is a rather small temple that was Romanesque in origin, but was later modified. It has an apse with arcades and Lombard bands, a square-plan bell tower, with a pyramidal cover, and a porch over the entrance. The striking mural paintings that once decorated the apse are now preserved in the Museu Nacional d'Art de Catalunya. The vault is presided over by a Christ in majesty and the Greek letters alpha and omega, flanked by the symbols of the evangelists, a cherub and seraph (with the text of the Sanctus) and the archangels Michael and Gabriel (with the latter still conserving the word Postulacius), who have eyes on their wings. All of these forms are quite similar to the paintings found at Estaón. The second part of the register, which is found between the windows, is less complete. Only the figures of Paul, John the Evangelist, Bartholomew, Thomas and Bernabé are left (this work dates from around the middle of the 12th century).


A quite large copy of the mural has recently been restored to the temple.
