The trevi fountain at the junction of three roads (tre vie) marks the terminal point of the "modern" Acqua Vergine, the revived Aqua Virgo, one of the ancient aqueducts that supplied water to ancient Rome as its mentioned in trevi fountain Rome map. In 19 BC, supposedly with the help of a virgin, Roman technicians located a source of pure water some 13 km (8.1 mi) from the city.

 

A traditional legend holds that if visitors throw a coin into the trevi fountain of Rome, they are ensured a return to Rome. This was the theme of 1954 Three Coins in the trevi Fountain and the Academy Award-winning song by that name which introduced the picture as you can see in trevi fountain Rome map. An estimated 3,000 euros are thrown into the fountain each day. The money has been used to subsidize a supermarket for Rome needy; however, there are regular attempts to steal coins from the fountain.
