Fontana dell'Acqua Paola is a monumental fountain located on the Janiculum Hill in Rome, Italy. It was built in 1612 to mark the end of the Acqua Paola aqueduct, with funds raised by Pope Paul V from taxes and other sources. The impressive fountain features five arches, through which abundant streams of water flow into five marble basins. The top of the fountain is adorned with the papal tiara and keys, above the Borghese family coat of arms of an eagle and dragon, supported by angels. One can also find an inscription praising Pope Paul in poetic terms. In addition, Fontana dell'Acqua Paola served as the inspiration for later Trevi Fountain. Its form and its large pools make it ideal for visitors looking to enjoy the splendor of the Roman fountains.
