Fontana del Tritone, Rome Fontana del Tritone, Rome Fontana del Tritone ("Triton Fountain") is a seventeenth-century fountain in Rome, by the Baroque sculptor Gian Lorenzo Bernini. Commissioned by his patron, Pope Urban VIII, the fountain is located in the Piazza Barberini, near the entrance to the Palazzo Barberini (which now houses the Galleria Nazionale d'Arte Antica) that Bernini helped to design and construct for the Barberini, Urban's family. This fountain should be distinguished from the nearby "Fontana dei Tritoni" (Fountain of the Tritons) by Carlo Francesco Bizzaccheri in Piazza Bocca della Verità which features two Tritons. The fountain was executed in travertine in 1642–43.

Della Porta designed the fountain, and Leonardo Sormani executed it. Due to the slope of the piazza, the fountain is approached by five steps on the south side, and only two on the north.
