2. 1251–1260Florence · FlorenceIn the mid-13th century, as the Florentine commune's economy and population grew, the baptistery served as the site of baptisms for all newborns and the starting point of major religious processions. Its size and location made it the symbolic center of urban public life, providing a reference point for later cathedral expansion and artist competitions.
3. 1330–1452Florence Baptistery · FlorenceAndrea Pisano and Lorenzo Ghiberti successively cast bronze reliefs for the south, east, and north doors, with the 1401 competition door (Gates of Paradise) becoming a turning point in Renaissance sculpture.
