Siena, city of Tuscany, in central Italy, stands out for its medieval brick buildings. Piazza del Campo, the central square with its characteristic fan shape, is home to the Palazzo Pubblico (the Gothic-style town hall) and the Torre del Mangia, a slender 14th-century tower from whose white battlements you can enjoy a wonderful view. The seventeen historic districts (the city districts) extend all around right from the square.
