The bell tower’s sculptural decoration is immense and includes one of the most complex figurative cycles of the Middle Ages, with 56 reliefs across two parallel registers and 16 life-size statues in the niches, created by the Florentine masters of the 14th and 15th centuries, including Andrea Pisano, Donatello and Luca Della Robbia.
In the hexagonal panels and lozenges are depictions of the Creation of Man, his Activities, the Liberal Arts, the Planets, the Virtues and the Sacraments. The statues in the niches represent the Patriarchs, Prophets, Kings of Israel and the Pagan Sibyls, including the beautiful group depicting the Sacrifice of Isaac by Donatello, a splendid example of the naturalism that was so popular in the 1400s. The originals of the sculptures are all inside the Museum of the Opera del Duomo behind the Cathedral.
Those who would like to enjoy an incredible view of Florence’s historic center can climb the bell tower: after 414 steps (there is no elevator), visitors will reach a large panoramic terrace overlooking the city.
