Around the 1550s, the church was enlarged by adding three small chapels, one containing the altar dedicated to Saint Catherine of Alexandria. In 1580, the altar was destroyed along with the chapel in order to build the new bell tower. When the ecclesiastical authorities approved this project, they ordered the relocation of the altar in a space which would have later become the Saint Rosario chapel.Document (May 28, 1582), Novara Diocesan Archive
