Designed and built to mark the terminus of the Trajan Aqueduct, between 1610 and 1614, by architects Giovanni Fontana (1540-1614) and Flaminio Ponzio (1560-1613) and Ippolito Buzio (1562-1634), sculptor, the fountain was commonly known as the Janiculum Fountain because it dominates the large terrace there that overlooks the city. It was commissioned by Pope Paul V of the Borghese family and it is their emblems – dragons and eagles – that can be seen in several places around the fountain itself.
It comprises five archways flanked by columns and topped with a large pediment complete with dedicatory inscription. White and multi-coloured marble stripped from the Roman Forum and the Temple of Minerva in the Forum of Nerva was used for the decorative elements of the fountains, whilst its red and grey columns used to be part of the St. Peter’s Basilica dating to the Constantine era.
Towards the end of the 17th century, the architect Carlo Fontana (1638-1714) altered the fountain’s facade into what it is today and a monumental semi-circular marble basin was added, substituting the five original basins located between the arches.
