The impressive façade of the house at numbers 11 and 13 on Via Massari features some distinctive concealed crenellations painted with courtly frescoes most probably in the second half of the 15th century. The sheer number of the frescoes on display, coupled with their good state of preservation, make this house particularly striking. It is almost as if the men and women depicted in these late Gothic-style paintings are looking out proudly from the balconies and windows just to show off their youthful charm and joie de vivre.
