The Torre del Mangia (or ‘Tower of the Eater’) is in Siena’s main square, the Piazza del Campo. Originally the tallest secular bell tower in Italy, it stands 334 feet (102 meters) tall, the same height as Siena Cathedral, in order to demonstrate that the state and the church held equal power. Visitors can climb the tight spiral stairs (all 400 of them) in order to be rewarded with a stunning view of the city below.
