Set in front of the Palazzo Poli, the Fontana di Trevi stands 25.9 meters (85 feet) high and 19.8 meters (65 feet) wide and is the largest Baroque fountain in the city.
"Taming of the waters" is the theme of the gigantic scheme that tumbles forward, mixing water and rockwork, and filling the small square. Tritons guide Oceanus' shell chariot, taming seahorses. In the niches flanking Oceanus, Abundance spills water from her urn and Salubrity holds a cup from which a snake drinks. Above, bas reliefs illustrate the Roman origin of the aqueducts.
A traditional legend says that visitors who throw a coin into the fountain are ensured a return to Roma. Approximately €3000 is thrown into the fountain each day and is used to subsidize a supermarket for the city's needy.
