Standing 25.9 meters high, this historical fountain is the largest baroque fountain in the city of Rome. Series of construction was made from 1732 to 1762. At the backdrop of the fountain is the Palazzo Poli. In the center is the superimposed robustly modelled triumphal arc. The center niche has free-standing columns for maximum light-and-shade. The bas reliefs illustrate the Roman origin of the aqueducts. The fountain was refurbished in 1998 - the stonework was scrubbed and the fountain was provided with reciprocating pumps. A traditional legend holds that if a visitor throw a coin into the fountain, they are ensured a return to Rome. (Rome, Italy / 2009)
