The Trevi Fountain surprised me the most. The Fountain always seemed larger in life in movies, television and in pictures. I was surprised by its size and the size of the piazza. The Fountain depicts Neptune standing on a chariot drawn by winged horses. It was completed in 1762 and was actually never a big tourist attraction until the movie, Three Coins in a Fountain. Throwing a coin over your shoulder into the fountain is supposed to ensure your return to Rome. My first attempt hit someone in the head, so I moved closer and had better success.
