The original sculptures on the tower's lower levels have been replaced by replicas to protect them from environmental damage.
The tower's design incorporates a specific geometry that uses the square of the base to determine the proportions of the upper sections.
Unlike many bell towers of the period, the structure is completely detached from the main cathedral building.
The seventh and largest bell, named 'Santa Reparata', weighs approximately 5,000 kilograms.
Giotto only supervised the construction for three years before his death, leaving the structural completion to his successors.
The hexagonal relief panels at the base illustrate the history of human civilization and the arts, a thematic choice unique for a religious bell tower.
Giotto's Bell Tower is a 84.7-meter tall free-standing campanile located in the Piazza del Duomo, serving as the bell tower for the Cathedral of Santa Maria del Fiore. Designed by Giotto di Bondone in 1334, the construction was continued by Andrea Pisano and completed by Francesco Talenti in 1359. The structure is clad in polychrome marble from Carrara, Prato, and Siena, featuring a complex decorative program of relief sculptures and hexagonal panels. Visitors can ascend 414 steps to reach the top terrace, which provides panoramic views of Florence and the Brunelleschi Dome. The tower is categorized as a site of historical and architectural significance within the UNESCO World Heritage site of the Historic Centre of Florence. It remains a functional bell tower, housing seven original bells cast between 1705 and 1956. The exterior is adorned with copies of statues originally created by artists including Donatello and Luca della Robbia, with the originals now preserved in the Museo dell'Opera del Duomo. The tower's foundation is deeper than standard for its era to compensate for the weight of the marble cladding.
