San Pietro in Montorio
The Fontana dell'Acqua Paola also known as Il Fontanone ("The big fountain") is a monumental fountain located on the Janiculum Hill, near the church of San Pietro in Montorio, in Rome, Italy. It was built in 1612 to mark the end of the Acqua Paola aqueduct, restored by Pope Paul V, and took its name from him. It was the first major fountain on the right bank of the River Tiber.
