The Baptistry of St John is located near the Duomo in the center of Siena. Built in the same Tuscan Gothic style, although less externally ornamented – the facade is unfinished. But it’s inside that is really worth seeing.
The baptismal font is hexagonal, decorated with panels depicting scenes from the life of John the Baptist, by leading artists of the 15th century: Donatello, Ghiberti, Giovanni di Turino and Jacopo della Quercia. Six sculptures represent Faith, Hope, Fortitude, Justice, Charity and Providence. There are bronze angels by Donatello and prophets by della Quercia. And completing the intense decorative motif, the walls and ceiling are frescoed.
