Sitting in the Val di Greve, it is named for the small, fast-flowing river that runs through it, is the principal town in the Chianti wine district which stretches south of Florence to just north of Siena . Until recently it has been a quiet, almost bucolic town because it was, and still is, well off the main roads. Even in ancient days Greve was not isolated because it was well-connected by secondary roads to the Via Volterrana and via Francigena. Nowadays, it is connected to the A1 superstrada between Florence and Rome and the main road between Florence and Siena . The old road network ensured easy access to Florence and to other places such as Figline where its tradesmen and farmers found ready markets for their goods and produce. The modern transportation network connects it to the world at large, enabling it to export great quantities of wine, and import vast quantities of tourists. Main sights: The Franciscan monastery is still at the heart of the old part of the city, as is the triangular main piazza, where a market has been running more or less continuously for centuries serving the nearby castle communities and hamlets. The piazza is fronted by numerous medieval aged buildings, including the 11th century Chiesa Santa Croce which was rebuilt in 1325 after being burned to the ground, along with the rest of the town, by the Duke of Lucca , Castruccio Castracani. After further renovation, the church, which houses paintings of the school of Fra Angelico, now features a neo-classical facade. In the piazza there is also a monument to the discoverer of New York harbor, Giovanni da Verrazzano (1485-1528), who was born nearby. In the frazione of Montefioralle is the church of Santo Stefano, with a late 13th century Madonna with Child and a 15th century Trinity and Saints. Also in the hamlet is a house which, according to the tradition, belonged to other explorer Amerigo Vespucci. In the nearby is a Romanesque Pieve with narthexed façade and two mullioned windows. At 2 km from the centre of Greve is the castle of Verrazzano, sitting on a 348 m-high hill. Built probably by the Lombards, it was a possession of the explorer's family, and in the 17th century was turned into a villa. Of the 13th century manor a tower remains. In the neighbourhood of the frazione of Panzano is the Pieve of San Leolino, known from the 10th century. The interior houses a 13th century panel by Meliore di Jacopo, a 15th century polyptych by the so called Master of Panzano, as well as works by Raffaellino del Garbo and Giovanni della Robbia.
