Campanile
The Gothic bell tower designed by Giotto (circa 1266–1337) is a soaring structure of multicolor marble originally decorated with sculptures by Donatello and reliefs by Giotto, Andrea Pisano, and others (which are now in the Museo dell'Opera del Duomo). A climb of 414 steps rewards you with a close-up of Brunelleschi's cupola on the Duomo next door and a sweeping view of the city.
