The Trevi fountain, or Fontana di Trevi, is the largest Baroque fountain in Rome, Italy. The fountain is placed at the juncture of three roads, hence the name tre vie. Originally a simple, small basin, Pope Urban VIII commissioned Bernini to design some possible renovations in 1629. When the Pope died, the project was abandoned, and wasn't revisited until 1730. Pope Clement XII commissioned Nicola Salvi for the final fountain, and work began in 1732. Salvi would pass away in 1751, 12 years before the fountain was completed, but Giuseppe Pannini would put the final touches on this amazing work of art.

The main theme behind the fountain is the Taming of the Waters, hence Neptune, the God of Water, placed in the center niche, being guided by Tritons. On either side of Neptune is Abundance, spilling water from her urn, and Salubrity, holding a cup of water from which a snake drinks. Neptune is framed by a triumphal arch, which is usually built to signify a victory in war.

A little-known fact on the "three coins" myth. It has been said, that if one throws three coins with one's right hand over their left shoulder, into the fountain, they would have good luck. This is all well and good, except the original three coins were thrown by three different individuals. The real legend is that, if you throw one coin in the fountain, you are ensured a return trip to Rome, two coins and you will get married, and three coins ensures divorce.
