The church of San Francesco in Pienza was built in the 14th century. Its architecture is Romanesque. It has a simple facade with a single entrance door and, inside, the walls are frescoed with scenes from the life of St Francis. After the Upper Basilica of Assisi and the Corridoio delle Stimmate (Corridor of the Stigmata) in Chiusi della Verna, these are the most complete frescoes depicting the life of the Saint of Assisi. The building can be totally attributed to the Middle Ages in the village of Corsignano, prior to that period of humanism that Enea Silvio Piccolomini transformed in Pienza when he became Pope Pius II. The frescoes are by Cristoforo di Bindoccio known as Malabarba and by Meo di Pero, Sienese painters in the second half of the fourteenth century. Inside, there is a plaque bearing the coat of arms of the Piccolomini family, in memory of the fact that the church contained the tomb of Enea's father, which was later transferred to Siena, where it was again located inside the church of San Francesco.
