Trevi Fountain: The fountain at the juncture of three roads (tre vie) marks the terminal point of the "modern" Acqua Vergine, the revivified Aqua Virgo, one of the ancient aqueducts that supplied water to ancient Rome. , finding the earlier fountain insufficiently dramatic, asked Bernini to sketch possible renovations, but when the Pope died the project was abandoned. Bernini's lasting contribution was to resite the fountain from the other side of the square to face the Quirinal Palace (so the Pope could look down and enjoy it).
