Battistero

Built in 1791 by Cardinal Giovanni Francesco Albani with an octagonal plan, symbol of resurrection (seven days of Creation, the eighth is the extra day, eternity), while the fountain has three doors and symbolizes the Holy Trinity.

The Baptistery was restored in 1998. The octagonal plan is a symbol of resurrection; the baptismal font, carved by Francesco Saverio Moschetti of Monte Giorgio, has three doors and symbolizes the Holy Trinity. In the main mirror, the precursor Saint John the Baptist is depicted in bas-relief figures in the act of baptizing the Savior. Inside the spring is preserved the copper water tray, with the Albani coat of arms.
On the walls, four lunettes tell the story of original sin; the painted pelican is an allegorical symbol referring to the Eucharist. The deer, the ostrich, the lion and the elephant, represented on the walls, symbolize the four cardinal virtues.
