Trevi Fountain
Located in a small square and entirely set against the Palazzo Poli. This fountain was designed by Nicola Salvi and completed in 1762. The sculpture in the middle is Neptun riding a chariot in the shape of a shell. The chariot is pulled by two sea horses. One horse is calm (symbolizing the quiet sea) and the other one is feral (symbolizing the rough sea). It derives its name from its position at the intersection of three roads (tre vie). The legend goes that if you throw a coin into the Trevi fountain, you will return to Rome.
