In the middle of the piazza is the Triton Fountain, designed by Gian Lorenzo Bernini in the 1640s. The piazza itself takes its name from the Palazzo Barberini, former home to a noble Roman family, one of whom eventually became Pope Urban VIII. That palace is now home to the Museum of Ancient Art.
Another fountain by Bernini - the Fountain of Bees - once occupied a corner of the Piazza Barberini, but it was moved to another spot on the nearby Via Vittorio Veneto. One of Rome’s two Metro lines (Line A) has a stop at the Piazza Barberini.
