When in Rome, do pay a visit to Fontana Di Trevi. This beautiful fountain is situated at the end of Aqua Virgo, and was constructed in 19 BC by Emperor Augustus’s son-in-law, Agrippa. One distinctive feature about the fountain is its size, as it is 65 feet wide and 85 feet high, and is the biggest fountain in the city. Trevi’s design has been changed several times since it was initially built, and the fountain is shaped like a triumphant arch, which occupies more than half the square. The main figure is Neptune, which is located right in the center and is the god of the sea. He is seen riding a chariot that is being pulled by two sea horses. On the left side of the figure, there is a statue which represents Abundance, whereas the statue on the right represents Salubrity. One thing that you should know about Fontana Di Trevi is that people visit the fountain to throw coins. You have to toss the coin with your back towards it, and you are not supposed to look behind while tossing. The monument is iconic and has appeared in several movies like When in Rome, Three Coins in the Fountain, and Roman Holiday.
