Via Veneto winds its way uphill from Piazza Barberini to Piazzale Brasile, passing the Capuchin Church of the Immaculate Conception and Palazzo Margherita—now home to the U.S. Embassy—along the way. Stars like Audrey Hepburn, Tennessee Williams, and Coco Chanel would once gather at the landmark Harry’s Bar, Café de Paris, and Doney Cafè that line the street. Today you can trace this route with a walking, Segway, or hop-on-hop-off bus tour of Rome’s most iconic sights by day or night. Film buffs can opt for a La Dolce Vita tour that hits on locations featured in Fellini’s most famous work, and art-and-architecture aficionados can take a tour focusing on the city’s most remarkable streets and squares, including Via Veneto and Piazza Barberini.
