The Trevi Fountain (Italian: Fontana di Trevi) is a fountain in the Trevi district in Rome, Italy, designed by Italian architect Nicola Salvi and completed by Giuseppe Pannini and several others. Standing 26.3 metres (86 ft) high and 49.15 metres (161.3 ft) wide, it is the largest Baroque fountain in the city and one of the most famous fountains in the world.
The fountain has appeared in several notable films, including Roman Holiday (1953), the eponymous Three Coins in the Fountain (1954), Federico Fellini's La Dolce Vita (1960), and The Lizzie McGuire Movie (2003).
In 1629, Pope Urban VIII, finding the earlier fountain insufficiently dramatic, asked Gian Lorenzo Bernini to sketch possible renovations, but the project was abandoned when the pope died. Though Bernini's project was never constructed, there are many Bernini touches in the fountain as it exists today. An early, influential model by Pietro da Cortona, preserved in the Albertina, Vienna, also exists, as do various early 18th century sketches, most unsigned, as well as a project attributed to Nicola Michetti one attributed to Ferdinando Fuga and a French design by Edmé Bouchardon.
Competitions had become popular during the Baroque era to design buildings, fountains, as well as the Spanish Steps. In 1730, Pope Clement XII organized a contest in which Nicola Salvi initially lost to Alessandro Galilei – but due to the outcry in Rome over a Florentine having won, Salvi was awarded the commission anyway. Work began in 1732.
