Florence Baptistery

The Florence Baptistery, also known as the Baptistery of Saint John (Italian: Battistero di San Giovanni), is a religious building in Florence, Italy. Dedicated to the patron saint of the city, John the Baptist, it has been a focus of religious, civic, and artistic life since its completion. The octagonal baptistery stands in both the Piazza del Duomo and the Piazza San Giovanni, between Florence Cathedral and the Archbishop's Palace.

Florentine infants were originally baptized in large groups on Holy Saturday and Pentecost in a five-basin baptismal font located at the center of the building. Over the course of the 13th century, individual baptisms soon after birth became common, so less apparatus was necessary. Around 1370 a small font was commissioned, which is still in use today. The original font, disused, was dismantled in 1577 by Francesco I de' Medici to make room for grand-ducal celebrations, an act deplored by Florentines at the time.
