Trevi Fountain is a fountain in the Trevi district in Rome, Italy, designed by Italian architect Nicola Salvi and completed by Pietro Bracci. Standing 86 feet high and 161 feet wide, it is the largest Baroque fountain in the city and one of the most famous fountains in the world. The backdrop for the fountain is the Palazzo Poli, given a new facade with a giant order of Corinthian pilasters that link the two main stories. Taming of the waters is the theme of the gigantic scheme that tumbles forward, mixing water and rock work, and filling the small square. Tritons guide Oceanus' shell chariot, taming hippocamps. In the center a triumphal arch is superimposed on the palazzo facade. The center niche or exedra framing Oceanus has free-standing columns for maximal light and shade. 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.
