The large prison that rises up at the walls, to the left of us, occupies the site of the Rocca that defended the town until the Florentine occupation in 1353. After that, a Dominican convent was built upon the spot--the convent in which Savonarola stayed while preaching the Lent in the Pieve. It was suppressed in the eighteenth century by the Austrian Grand Duke of Tuscany. Opposite to it, in the Via del Castello, is the little church of San Lorenzo in Ponte, with a few unimportant frescoes of the Trecento. Passing under the Arco de' Talei into the Via San Giovanni, we see a large piece of the first circuit of walls on the right, adjoining the Portone, blackened apparently by fire, and the tall Torre Talei. Opposite the tower is a shrine, with a ruined fresco by Mainardi. In the refectory of a former convent of Benedictine nuns (now the Palazzo Pratellesi) is a very Peruginesque fresco by Vincenzo Tamagni, representing the mystical marriage of St Catherine of Alexandria; it is dated 1528. On the left is the dismantled façade of San Giovanni, a building of the eleventh century. Over the inside of the gate is a chapel built in 1601 to cover a venerated picture, but the outside of the Porta San Giovanni is still unspoiled thirteenth century architecture. A short way beyond the Porta San Giovanni is the former monastery of Monte Oliveto, founded in 1340 by Giovanni di Gualtiero Salvucci. In the lunette over the door of the church is a fresco of the Madonna between two white-robed monks, possibly by Tamagni. There is a Madonna of 1502 in the church by Mainardi, and two Sienese pictures of the school of Lippo Memmi are in the sacristy. In the cloister is a frescoed Crucifixion by Benozzo Gozzoli, with St Jerome beating his breast and saying the Rosary at the foot of the Cross. Beyond Monte Oliveto, a road of olives and barley fields leads to the small hamlet of Santa Lucia. In its church are a fresco of the Crucifixion, with a little Dominican kneeling at the foot, by Pier Francesco, and a picture by Fra Paolino--one of those compositions of Madonnas and Saints that he inherited from Fra Bartolommeo. Outside the Porta San Matteo is the convent of the Cappuccini. In its church is a Deposition from the Cross of 1591, ascribed to Jacopo Ligozzi of Verona. About two miles further on, with a splendid view over the valley, is Cellole, a Romanesque church of the first years of the thirteenth century. Attached to it was the Leper Hospital, where San Bartolo devoted his life to the stricken and where at last, himself overtaken by the fell disease, he became one with the rest and died.
