The Trevi Fountain is a fountain in the Trevi district in Rome, Italy. Standing 26.3 metres (86 ft) high and 49.15 metres (161.3 ft) wide, it is the largest Baroque fountain in the city and one of the most famous fountains in the world.The 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 aqueducts that supplied water to ancient Rome. 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. (This scene is presented on the present fountain's façade.) However, the eventual indirect route of the aqueduct made its length some 22 km (14 mi). This Aqua Virgo led the water into the Baths of Agrippa. It served Rome for more than 400 years.The coup de grâce for the urban life of late classical Rome came when the Goth besiegers in 537/38 cut off the aqueducts. Medieval Romans were reduced to drawing water from polluted wells and the Tiber River.
