The Church of San Francesco was built for the Franciscan friars, who settled there in 1457 and dedicated to the Saint of Assisi who remembered Blessed Giovanni da Penna in his “Fioretti”. Then renovated in 1700 in Baroque style, it remains adorned with fifteenth-century frescoes, preserving the original portal and the terracotta floor, the tombs of the ancient noble families and various paintings of the fifteenth and eighteenth centuries.
