Discover the city’s most famous cathedral and step into centuries of Renaissance history.
The Duomo of Florence complex is a centralized hub of religious history and Renaissance engineering. This site represents the transition from medieval traditions to the innovations of the 15th century. It is composed of the following elements and buildings:
Construction of the cathedral began in 1296 under the direction of Arnolfo di Cambio to replace the church of Santa Reparata. The project was funded by the Florentine Republic and the silk and wool guilds, utilizing a facade composed of white, green, and pink marble from Carrara, Prato, and Maremma.
The interior was built to accommodate a capacity of 30,000 people. The architectural layout follows a Latin cross plan with a nave and transept, utilizing mathematical principles and proportions. Throughout its 140-year development, the building integrated Gothic and Renaissance elements.
While the exterior features reliefs and statues depicting biblical figures, the interior maintains a focus toward the high altar and the stained glass windows. The building functioned as a civic and spiritual center.
The interior floor of the Duomo consists of a marble mosaic pavement started in the 16th century. This work uses the same color palette as the exterior—white, green, and red marble—arranged in complex geometric patterns.
Designed by artists such as Baccio d’Agnolo and Francesco da Sangallo, the floor covers the entire nave and serves to organize the internal space. The maintenance of these mosaics is a continuous task for the Opera del Duomo, as the wear from visitors requires periodic restoration to preserve the symmetry and color of the stone.

Across from the cathedral stands the Duomo Florence Baptistery of St. John (Battistero di San Giovanni). Its bronze doors, known as the Gates of Paradise, depict biblical scenes. It’s where Dante Alighieri was baptized—a connection to the great poet’s life. As you stand within its octagonal walls, imagine the echoes of centuries past.
Adjacent to the cathedral stands Giotto’s Campanile, a freestanding bell tower. Its elegant Gothic design complements the Duomo perfectly. Rising to an impressive 84.7 meters (278 feet), it offers a different perspective—one that captures the city’s rooftops and the rolling Tuscan hills. Climb the 414 steps, and you’ll feel the heartbeat of the Duomo Florence bell tower.
Campanile di Giotto, as it is known in Italian, graces the Piazza del Duomo in Florence, Italy. This iconic medieval bell tower stands as a masterpiece of Italian Gothic architecture, showcasing Florence’s rich artistic and cultural heritage.
