Siena [1] is a medieval city in the region of Tuscany, located in the north of Italy some 70 km (43 mi) south of Florence. It is probably best known for a colourful horse race, Il Palio, conducted twice each year in the summer.
Siena produced some of the greatest Italian painters of the 13th and 14th centuries; many masterpieces by Duccio di Buoninsegna, Simone Martini, Pietro and Ambrogio Lorenzetti, and Sassetta are found in Sienaâs art gallery (in the Buonsignori Palace) as well as in the Public Palace and the Museum of Works of the Duomo.
