Fontana dell'Acqua Paola

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.

The Fontana dell'Acqua Paola was inspired by the popularity of the Fontana dell'Acqua Felice, built in 1585-88 by Pope Sixtus V. Pope Paul V decided to rebuild and extend the ruined Acqua Traiana aqueduct built by the Emperor Trajan in order to create a source of clean drinking water for the residents of the Janiculum Hill, who were forced to take their water from brackish springs or from the polluted Tiber. He raised funds for his project in part by imposing a tax upon wine, which caused complaints among some residents. The funding from this tax and other sources allowed him to purchase the rights to the water of a spring near Lake Bracciano, not far from Rome, as the source for the fountain.

The fountain was designed by Giovanni Fontana, whose brother had worked on the Fontana dell'Acqua Felice, and Flaminio Ponzio. They used white marble from the nearby ruins of the Roman Temple of Minerva in the Forum of Nerva, and constructed a massive gateway of five arches for the arrival of the water. At the top of the fountain are the papal tiara and keys, above the Borghese family coat of arms of an eagle and a dragon, supported by angels. The inscription praises Pope Paul in poetic terms for bringing water to the residents of the district.

Unlike the Fontana dell'Acqua Felice, which had an abundance of statues on biblical themes, the theme of the Fontana dell'Acqua Paola was water. Five abundant streams poured through the arches into five marble basins. In 1690 Carlo Fontana designed an additional semcircular pool for the water which overflowed from the marble basins. Marble posts were put in place to keep coachmen from watering their animals in the fountain, but the pool was tempting to many local residents, who bathed in the water. An ordinance was issued in 1707 forbidding residents to bathe in the fountain.
