Fontana dell'Acqua Felice. The Fontana dell'Acqua Felice, also called the Fountain of Moses, is a monumental fountain located in the Quirinale District of Rome, Italy.
It marked the terminus of the Acqua Felice aqueduct restored by Pope Sixtus V. It was designed by Domenico Fontana and built in 1585-88. At the beginning the reign of Pope Sixtus V in 1585, only one of the ancient Roman aqueducts which brought water to the city, the Aqua Vergine, was still being maintained and working.
Everyone in Rome who wanted clean drinking water had to go to the single fountain near the site of today's Trevi Fountain. Pope Sixtus took on the responsibility of restoring other aqueducts, including the Acqua Alessandrina, which he renamed Acqua Felice after himself.
The new fountain that marked the terminus of the restored aqueduct was the first new monumental wall fountain in Rome since antiquity. The initial effort to build the aqueduct, by architect Matteo Bartolini, was a failure: Bartolini miscalculated the incline of the channel, so the flow of water was much less than needed reach the Quirinal Hill, the intended site of its terminal fountain.
Giovanni Fontana took over the building of the aqueduct, which was completed by June 1587. A fountain was constructed by architect engineer Domenico Fontana in the form of an ancient Roman triumphal arch. It featured, as ancient Roman fountains did, an inscription honoring it
