St. Francis’ Church, which rises a few metres from the walls with a bell tower that must have represented an excellent vantage point, has some Romanesque features on the facade that suggest a much older origin than 1350, the year of the papal concession to Friars Minor. Inside is a remarkable organ by the famous craftsman Callido of the 1700s, previously housed in the Duomo.After restoration works in 1960, the Poor Clares nuns were received in the adjoining monastery and perpetual adoration was established in the church. Next to St Francis’ Church there is a shady, picturesque small square which is well worth a stop.
