Another remnant of ancient Rome awaits your exploration at Piazza Bocca della Verità. On the left is the Temple of Hercules Victor. Hercules the Winner is a reference to his success performing the 12 Labors. The circular building supported by twenty, 35 foot Corinthian columns originates from the 2nd century BC. This is the oldest marble building in Rome. The temple was converted into the church of Santo Stefano alle Carozze in 1132. It was dedicated to Saint Mary of the Sun in the 17th century. On the right is the Fountain of the Tritons. Fontana dei Tritoni was crafted in the 17th century by Baroque sculptor Carlo Bizzaccheri at the bequest of Pope Clement XI.
