Fodor's Expert Review Quattro Fontane

This intersection takes its name from its four Baroque fountains, which represent the Tiber (on the San Carlo corner), the Arno, Juno, and Diana. Despite the nearby traffic and the tightness of the sidewalk, it's worth taking in the views in all four directions from this point: to the southwest, as far as the obelisk in Piazza del Quirinale; to the northeast, along Via XX Settembre to the Porta Pia; to the northwest, across Piazza Barberini to the obelisk of Trinità dei Monti; and to the southeast, as far as the obelisk and apse of Santa Maria Maggiore. The prospect is a highlight of Pope Sixtus V's campaign of urban beautification and an example of Baroque influence on city planning.
