Siena, a city in central Italy’s Tuscany region, is distinguished by its medieval brick buildings.

The fan-shaped central square, Piazza del Campo, is the site of the Palazzo Pubblico, the Gothic town hall, and Torre del Mangia, a slender 14th-century tower with sweeping views from its distinctive white crown. The city’s 17 historic “contrade” (districts) extend outward from the piazza.
