 Meanwhile, the northern portico has a similar design, but with other motifs on the capitals, and the tympanum is identifiable by a sculpted Agnus Dei.The main chapel has a series of blind arches on the wall (a remnant from the earlier, 11th century building) and is illuminated by three narrow windows.Two capitals of the triumphal arch (between the main chapel and the nave) were reused from an ancient building, possibly a 10th-century church in this same spot.
