Rome's magnificent Trevi Fountain stands as the city's largest and most theatrical Baroque fountain, where the thundering cascade of water has drawn visitors since its completion in 1762. Designed by Nicola Salvi and completed by Giuseppe Pannini, the monumental 86-foot-high, 161-foot-wide travertine masterpiece depicts Neptune's chariot led by Tritons with sea horses – one wild, one docile – representing the ocean's varying moods. The fountain marks the terminus of the ancient Aqua Virgo aqueduct, which has supplied water to Rome since 19 BCE. Literary and cinematic appearances, most famously in Fellini's "La Dolce Vita," have cemented the fountain's romantic allure. Visitors maintain the tradition of tossing coins with their right hand over their left shoulder – an estimated 3,000 euros daily – ensuring their return to the Eternal City, with proceeds supporting Roman charities. As both a stunning artistic achievement and a living piece of Roman social life, the Trevi embodies the theatrical public spaces that have defined Roman urban culture for centuries.
