In the 15th century the three side chapels are closed and are replaced by a single large side chapel that corresponds to the large semicircular arch in the center of the left side. On the opposite wall a series of altars are built, they probably are similar to the existing one with the statue of the Madonna and child. In this period probably all the 14th century fresco decorations are painted over and the church takes a more sober Renaissance interior décor.
