Fontanone di Ponte Sisto

The Fontana or Fontanone di Ponte Sisto, once known as the Fontanone dei Cento Preti, is an early 17th-century, monumental fountain now located in Piazza Trilussa, facing the south end of the Ponte Sisto, in Trastevere, Rome, Italy. It was reconstructed here in the late 19th century, originally erected across the river, attached to the former building of the Collegio Ecclesiastico.
