This is a monumental public fountain located along Via Garibaldi at Janiculum Hill in Trastevere. It was designed by Giovanni Fontana in 1612 based on the concept of Fontana dell'Acqua Felice. You will find five streams pouring into a ground level basin that was added in 1690 as well as a column lined facade with empty niches above. The fountain monument is quite colossal and interesting to see if sightseeing in Trastevere. It can be conveniently visited before or after spending a bit of time at nearby Church of San Pietro in Montorio. This is also a nice elevated position for views of the lower Trastevere and city centre to the east across the Tiber.

We climbed up Janiculum Hill from via Garibaldi below. The first attraction we came across was this beautiful fountain that was built in the early 1600s! Pope Paul V had it built to provide clean drinking water to nearby residents. Nice! The fountain's structure is made of white marble (repurposed from the ruins of the Roman Temple of Minerva). There are five arches acting as a gateway for the water flowing in. At the top, you can see the papal symbols, the Borghese family coat of arms, and a tribute to the Pope. In front there is a large pool that looks pretty refreshing on a hot day. A low iron fence with pillars rings the fountain to keep people out of the fountain or sitting on its edge. You do need to be aware that a road runs right in front of the fountain, so it can be dangerous crossing the street for a better view of the fountain or to enjoy views of the city of Rome below.

We arrived here after walking down a different way from Janiculum hill and come across this fountain. Really great view of the fountain which is big. Also you can cross the road and see Rome from high up.
