It would take days to get to know this extraordinary city and certainly it would not be enough, so we limit ourselves to recommending some of the many points of interest present, offering you a brief peek on Siena, crossing one of its central artery. It starts from Piazza San Domenico, making a brief stop inside the Basilica of San Domenico, one of the most important churches in the city, built in the thirteenth century and still today the guardian of the head / relic of Saint Catherine of Siena. To continue along the main artery of the city, Via Banchi di Sopra which crosses Siena from north to south. Noble palaces of different architectural styles flank the road until reaching the highest point of the city, Piazza Duomo, where the Cathedral of Santa Maria Assunta rises majestically. The Cathedral of Siena is a masterpiece of Gothic-Roman art that contains within it works of sculpture and painting created by the most important masters of the European artistic panorama. Unique and extraordinary is the grandiose marble and graffiti floor, for the technique used and for the choice of the message, of the figurations. The monumental complex of the Duomo “Museo dell’Opera” is open to the public and includes, in addition to the entrance to the Cathedral, the Floor, the Piccolomini Library and the “Porta del Cielo”, also the “Duomo Nuovo” Museum, the Crypt and the Baptistery. Right in front of the Cathedral is the complex of Santa Maria della Scala, one of the oldest hospitals in Europe, where pilgrims and travelers who passed along this stretch of the Via Francigena have been welcomed for centuries. The complex houses a vast artistic heritage, enhanced by temporary exhibitions. Our route continues to Piazza del Campo, with its unmistakable shell shape and terracotta flooring, considered one of the most beautiful in the world and where the traditional and folkloric Palio delle Contrade takes place twice every year. Tourist area par excellence, Piazza del Campo is lined with bars, restaurants and shops that do not overshadow the beauty of the place, embellished by the Palazzo Pubblico and the majestic Torre del Mangia, 87 meters high.
