Piazza delle Erbe (Padua) Piazza delle Erbe (Padua) Piazza delle Erbe is one of the many squares in the historic center of Padua. For centuries, with Piazza della Frutta, it was the commercial center of the city. In the two squares is one of the largest markets in Italy. Unlike Piazza dei Signori, the civic theater of celebrations, Piazza delle Erbe was the site of the folk festivities. The square is dominated by the imposing Palazzo della Ragione. The area was active in pre-Roman times. By the time of Imperial Rome, homes gave way to businesses. Its present design is from the tenth and
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.
