Claim: 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, built by Della Porta, was unable to jet water high into the air.
Evidence: 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 fountain was one of a group of sixteen fountains built by Della Porta following the reconstruction of the Acqua Vergine aqueduct, a project begun by Pope Pius IV in 1561 and finished by Pope Pius V in 1570.
