In Piazza San Francesco there is the homonymous church of fourteenth-century plant, inside we point out the famous Crucifix on wood (1285 approx.) attributed to Duccio di Boninsegna, although after recent studies on the work there is uncertainty whether to attribute the authorship to Duccio di Boninsegna or to the Sienese Master of Badia a Isola. However, whoever the author may be, the work is of enormous artistic importance as the author breaks away from the conventionality of Tuscan artists of the period and is undoubtedly one of the most important in the whole of Tuscany. Note the transparent and fluttering loincloth that recalls that of Cimabue in the Basilica of Assisi. Going back to the church, in the right chapel you can admire the frescoes painted by Antonio and Francesco Nasini. On the left side, instead, there was the Franciscan convent of which today remains a well-kept cloister with the sixteenth-century Pozzo della Bufala.
