The Cathedral of Santa Maria del Fiore, known as the Duomo of Florence, is the monumental heart of the city, one of the greatest Gothic and early Renaissance masterpieces in Italy. Founded in 1296 by Arnolfo di Cambio and consecrated in 1436, it is famous for Brunelleschi's majestic dome (the largest masonry dome in the world), its white, green, and red marble façade, and the adjacent Giotto's Bell Tower.
It is one of the largest churches in Christendom, measuring 160 meters in length and over 100 meters high to the dome's lantern. The exterior is characterized by polychrome marble, while the interior is spacious and sober, with 16th-century marble floors.
Brunelleschi's Dome: An engineering masterpiece, it was built between 1420 and 1436 without external supports, using a "herringbone" technique with over 4 million bricks. Inside, it houses the colossal fresco of the Last Judgement by Vasari and Zuccari.
History and Artists: The work took approximately 140 years to complete, involving great masters such as Arnolfo di Cambio, Giotto (who designed the bell tower), and Brunelleschi. The current façade is in Neo-Gothic style, completed between 1871 and 1887.
In addition to the dome, the complex includes Giotto's Bell Tower, the Baptistery of San Giovanni (famous for Ghiberti's Gates of Paradise), and the Museo dell'Opera del Duomo, which houses original works such as Michelangelo's Pietà Bandini.
