The octagonal Baptistery of San Giovanni faces Florence's cathedral across Piazza del Duomo and predates it by centuries; Dante was baptized here and wrote about it in the Divine Comedy. Its greatest fame rests on three sets of bronze doors: Andrea Pisano cast the south doors in 1330, Lorenzo Ghiberti won a famous 1401 competition against Brunelleschi for the north doors, and his east doors, made between 1425 and 1452, so impressed Michelangelo that he reportedly called them the Gate of Paradise, the name they still carry. What visitors see today on the east side are copies; Ghiberti's originals, cleaned after the catastrophic 1966 flood, now live protected in the Opera del Duomo Museum. Inside, a 13th century gold ground mosaic ceiling depicts the Last Judgment over the octagonal font where the city's children were christened for centuries.
The Baptistery of San Giovanni was one of medieval Florence's most important religious monuments and remained the city's baptismal church for centuries. Its mosaics, marble revetment, and bronze doors connect Romanesque Florence to the early Renaissance. Together with the cathedral and Giotto's Campanile, it belongs to the UNESCO-listed historic center of Florence and anchors the sacred geometry of Piazza del Duomo.
