The church of San Francesco was built in the mid-13th century and expanded in the early 1700s.
The church has a Romanesque-Gothic facade of white limestone from Monte Cucco.
It is the only architectural element of medieval origin still visible. In the 17th and 18th centuries the church was renovated and expanded. The façade features a rose window and a portal with embrasure distinguished by fillets of decorated columns. At the base of the columns there are jambs decorated with bas-reliefs. On the bas-reliefs there are animal shapes related to the Romanesque figurative culture. The rose window above has slender columns softened by foliage and other decorative motifs carved in bas-relief on the capitals.
