Incorporated into the Seu Vella, the church is built in a transitional style (13C) as is shown by its remarkably varied capitals. Those in the apses and the transept illustrate themes from the Old Testament, while those in the nave and aisles favour scenes from the New Testament. Moorish influences can be seen in the exterior, particularly in the carving on the doors. The finely sculpted capitals of the two doorways are reminiscent of Moorish stuccowork. The style has come to be known as the Romanesque School of Lleida.
