“The world is a book, and those who do not travel read only a page.”
Sensory overload is the theme of Trevi, with Neptune kicking up a tempest in its signature fountain, Quirinale Palace fit for popes and kings and baroque masterpiece churches by Borromini and Bernini facing off across Via del Quirinale (San Carlo alle Quattro Fontane and Sant'Andrea, respectively). The people-watching at Trevi's sidewalk cafés is arguably Rome's best, and that's saying something. Every romantic in town shows up here around sunset, starry-eyed and shamelessly smooching. Cavorting in Trevi Fountain is technically off-limits since Fellini filmed La Dolce Vita here, but night-time visitors still hope for a glimpse of the notorious D'Artangan, who's been caught twice stealing thousands of Euros thrown into the fountain for good luck. But the real treasure of Trevi is Palazzo Barberini, a 17th century palace packed with Renaissance and baroque masterpieces and capped with Pietro da Cortona's Triumph of Divine Providence ceiling. Fair warning: divine providence may be necessary to find an affordable hotel in the area.
