The Trevi Fountain is the most famous and arguably the most beautiful fountain in all of Rome.
The Trevi Fountain (Fontana di Trevi) is at the ending part of the Aqua Virgo, an aqueduct constructed in 19 BC. It brings water all the way from the Salone Springs and supplies the fountains in the historic center of Rome with water.
In 1732, Pope Clement XII commissioned Nicola Salvi to create a large fountain at the Trevi Square . A previous undertaking to build the fountain after a design by Bernini was halted a century earlier after the death of Pope Urban VIII. Salvi based his theatrical masterpiece on this design. Construction of the monumental baroque fountain was finally completed in 1762.
The central figure of the fountain , in front of a large niche, is Neptune , god of the sea. He is riding a chariot in the shape of a shell, pulled by two sea horses. Each sea horse is guided by a Triton. One of the horses is calm and obedient, the other one restive. They symbolize the fluctuating moods of the sea.
On the left hand side of Neptune is a statue representing Abundance, the statue on the right represents Salubrity. Above the sculptures are bas-reliefs, one of them shows Agrippa, the girl after whom the aqueduct was named.
A traditional legend holds that if visitors throw a coin into the Trevi Fountain, they are ensured a return to Rome . Among those who are unaware that the "three coins" of Three Coins in the Fountain were thrown by three different individuals, a reported current interpretation is that two coins will lead to a new romance and three will ensure either a marriage or divorce. A reported current version of this legend is that it is lucky to throw three coins with one's right hand over one's left shoulder into the Trevi Fountain .
Approximately 3,000 euros are thrown into the Trevi Fountain each day. The money has been used to subsidize a supermarket for Rome's needy. However, there are regular attempts to steal coins from the Trevi Fountain.
