3. Trevi Fountain
Nicola Salvi's 85-foot-high, 18th-century fountain — filled with Baroque sea gods and horses — epitomizes passion and romance. This is where Anita Ekberg bathed in Federico Fellini's 1960 film classic La Dolce Vita. It's also where young secretaries searched for love in the 1954 American movie Three Coins in the Fountain. According to local legend, if you throw a coin over your shoulder into the fountain, a wish for a return visit to Rome will come true.
