This is a list of the notable fountains in Rome, Italy. Rome has fifty monumental fountains and hundreds of smaller fountains, over 2000 fountains in all, more than any other city in the world.
For more than two thousand years fountains have provided drinking water and decorated the piazzas of Rome. During the Roman Empire, in 98 AD, according to Sextus Julius Frontinus, the Roman consul who was named curator aquarum or guardian of the water of the city, Rome had nine aqueducts which fed 39 monumental fountains and 591 public basins, not counting the water supplied to the Imperial household, baths and owners of private villas. Each of the major fountains was connected to two different aqueducts, in case one was shut down for service.
After the fall of the Western Roman Empire, the aqueducts were wrecked or fell into disrepair, and the fountains stopped working. In the 14th century, Pope Nicholas V (1397–1455), a scholar who commissioned hundreds of translations of ancient Greek classics into Latin, decided to embellish the city and make it a worthy capital of the Christian world. In 1453 he began to rebuild the Acqua Vergine, the ruined Roman aqueduct which had brought clean drinking water to the city from eight miles (13 km) away. He also decided to revive the Roman custom of marking the arrival point of an aqueduct with a mostra, a grand commemorative fountain. He commissioned the architect Leon Battista Alberti to build a wall fountain where the Trevi Fountain is now located. Alberti restored, modified, and expanded the aqueduct that supplied both the Trevi Fountain as well as the famous baroque fountains in the Piazza del Popolo and Piazza Navona.
One of the first new fountains to be built in Rome during the Renaissance was the Fountain in Piazza Santa Maria in Trastevere (1499), which was placed on the site of an earlier Roman fountain. Its design, based on an earlier Roman model, with a circular vasque on a pedestal pouring water into a basin below, became the model for many other fountains in Rome, and eventually for fountains in other cities, from Paris to London.
