Palazzo Braschi Palazzo Braschi is a large Neoclassical palace in Rome, Italy and is located between the Piazza Navona, the Campo de' Fiori, the Corso Vittorio Emanuele II and the Piazza di Pasquino. It presently houses the Museo di Roma, the "museum of Rome", covering the history of the city in the period from the Middle Ages through the nineteenth century. It was built by the papal nephew Duke Luigi Braschi Onesti, to designs by
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.
