The Trevi Fountain or Fontana di Trevi tops the list of the most celebrated fountains in Rome, if not the world. An iconic symbol of the city, it's a top free attraction (except for the coin you may want to toss in), drawing an estimated 1,200 people to the site every hour.
The most famous practice at the Trevi Fountain is to throw a coin over the shoulder into the fountain. There are no special rules for the coin toss. However, it is important that the coin lands in the fountain to fulfill the wish.
It is tradition that if you throw a coin into the fountain, you will one day return to Rome. You are supposed to do this with your back to the fountain, though it is still pretty unlikely that you could miss.
