4 Best Sights in Rome, Italy

Mostly enclosed within high walls that recall the papacy's stormy history, the Vatican opens the spectacular arms of Bernini's colonnade to embrace the world only at St. Peter's Square, scene of the pope's public appearances and another of Bernini's masterpieces. The elliptical Piazza di San Pietro was completed in 1667—after only 11 years' work—and holds about 100,000 people.

Surrounded by a pair of quadruple colonnades, the piazza is gloriously studded with 140 statues of saints and martyrs. At its center is the 85-foot-high Egyptian obelisk, which was brought to Rome by Caligula in AD 37 and moved here in 1586 by Pope Sixtus V. The famous Vatican post offices can be found on both sides of St. Peter's Square and inside the Vatican Museums complex. The main information office is just left of the basilica as you face it.

At the very heart of the Trastevere rione (district) lies this beautiful piazza, with its elegant raised fountain and sidewalk cafés. The centerpiece is the 12th-century church of Santa Maria in Trastevere, first consecrated in the 4th century. Across countless generations, this piazza has seen the comings and goings of residents and travelers, as well as intellectuals and artists, who today often lounge on the steps of the fountain or eat lunch at an outdoor table at Sabatini's. At night, the piazza is the center of Trastevere's action, with street festivals, musicians, and the occasional mime vying for attention from the many people taking the evening air.

One of Trastevere's most historic and time-burnished squares (albeit one that's now a bit overrun by traffic), this piazza takes its name from ancient Roman baths on the site (piscina means "pool"). It's said that the tiny church of San Benedetto on the piazza was built on the home of Roman nobles in which St. Benedict lived in the 5th century. Opposite is the medieval Casa dei Mattei (House of the Mattei), where the rich and powerful Mattei family lived until the 16th century, when, after a series of murders on the premises, colorful legend has it that they were forced to move out of the district, crossing the river to build their magnificent palace close to the Jewish Ghetto.

Piazza Venezia stands at what was the beginning of Via Flaminia, the ancient Roman road leading northeast across Italy to Fano on the Adriatic Sea. From this square, Rome's geographic heart, all distances from the city are calculated.

The piazza was transformed in the late 19th century when much older ruins were destroyed to make way for a modern capital city (and a massive monument to unified Italy's first king). The massive female bust near the church of San Marco in the corner of the piazza, a fragment of a statue of Isis, is known to the Romans as Madama Lucrezia. This was one of the "talking statues" on which anonymous poets hung verses pungent with political satire, a practice that has not entirely ended.

The Via Flaminia remains a vital artery. The part leading from Piazza Venezia to Piazza del Popolo is now known as Via del Corso, after the horse races (corse) that were run here during the wild Roman carnival celebrations of the 17th and 18th centuries. It also happens to be one of Rome's busiest shopping streets.
