Very austere Romanesque building, with a well-worked ashlar façade that denotes its construction in the first half of the 12th century. Later, in the Romanesque building, a side chapel and the sacristy were added to the southern façade, and to the north, a chapel and a niche. The apse has a double central slit window invisible from the inside due to the presence of a modern altar. The vault of the apse and the arch of the presbytery are of semicircular profile unlike the one of the ship, constructed later, that is of pointed profile which rests on a cornice.

On the south wall we find the original door that was walled up when the current one was opened on the west façade, on which the frontispiece rises.
