Piazza Barberini century, unknown human corpses were displayed here for public identification. Between 1632 and 1822 an antique obelisk stood here; it was transferred to Villa Medici. Today, the piazza is large crossroad for Rome's traffic and, since 1980, has accommodated a station on Line A of the Rome Metro, called "Barberini – Fontana di Trevi". . Piazza Barberini Piazza Barberini is a large piazza in the "centro storico" or city center of Rome, Italy and situated on the Quirinal Hill. It was created in the 16th century but many of the surrounding buildings have subsequently been rebuilt. The current appellation was
Fontana di Piazza Colonna to the foot of the column of Marcus Aurelius. The source of the water for the fountain of Piazza Colonna was only 67 feet above sea level; like the Trevi Fountain, the Fontana della Barcaccia, and the fountains of Piazza Navona, all connected to the Acqua Vergine, the fountain of Piazza Colonna was unable to jet water high into the air. The original project of Della Porta was to place an antique Roman statue of a sea god, called Marforio, in the fountain, against a background of a rocky grotto, behind which the column of Marcus Aurelius would be seen.
