The Trevi Fountain (Italian: Fontana di Trevi) is an 18th-century fountain in the Trevi district in Rome, Italy, designed by Italian architect Nicola Salvi and completed by Giuseppe Pannini and several others. Standing 26.3 meters high and 49.15 meters wide, it is the largest Baroque fountain in the city and one of the most famous fountains in the world.
The Trevi Fountain took some 30 years to complete, and after Salvi’s death in 1751, Giuseppe Pannini, who slightly altered the original scheme, oversaw its completion in 1762.
The backdrop for the fountain is the Palazzo Poli, given a new façade with a giant order of Corinthian pilasters that link the two main storeys. Taming of the waters is the theme of the gigantic scheme that tumbles forward, mixing water and rockwork, and filling the small square. Tritons guide Oceanus’s shell chariot, taming hippocamps.
At its center is Pietro Bracci’s statue of Oceanus, which stands atop a chariot pulled by sea horses and is accompanied by tritons. The fountain also features statues of Abundance and Health. Its water, from the ancient aqueduct called Acqua Vergine, long was considered Rome’s softest and best tasting; for centuries, barrels of it were taken every week to the Vatican. However, the water is now nonpotable.
The legend of the Trevi Fountain says you should stand with your back to the fountain and toss a coin over your left shoulder to guarantee a return trip to Rome.
An estimated 3,000 euros are thrown into the fountain each day. In 2016, an estimated €1.4 million (US$1.5 million) was thrown into the fountain. The money has been used to subsidize a supermarket for Rome’s needy; however, there are regular attempts to steal coins from the fountain, even though it is illegal to do so.
The fountain has appeared in several films, including Roman Holiday (1953); Three Coins in the Fountain (1954); Federico Fellini’s classic, La Dolce Vita (1960); Sabrina Goes to Rome (1998); and The Lizzie McGuire Movie (2003).
The square in front of the Trevi Fountain is open to visitors all day. You may visit the Trevi Fountain during the day or in the evening, to see its beautiful illumination. You can even come to the Trevi Fountain at night if you wish since the Trevi Fountain is open and accessible 24 hours a day and 7 days a week.
