In 1732 Pope Urban commissioned Nicola Salvi to create the largest Baroque fountain in Rome. The central figure of the fountain is Neptune riding a shell chariot pulled by two seahorses.
Legend tells that by throwing a coin over your shoulder into the fountain, you will return to Rome.
The fountain is famous for the movies 'Three coins in a fountain','Roman Holiday' and Federico Fellini's 'La Dolce Vita'.
