The ancient Romans also had a complex system of aqueducts, which were used to transport water across long distances. The first Roman aqueduct was built in 312 BCE. The eleventh and final ancient Roman aqueduct was built in 226 CE. Put together, the Roman aqueducts extended over 450 kilometers, but less than seventy kilometers of this was above ground and supported by arches.

In 1561, Pope Pius IV decided to completely reconstruct the aqueduct. The project was given to the Papal architect, Giacomo della Porta (1532–1602), who built some of Rome's most famous fountains, and also completed the dome of St. Peter's Basilica following Michelangelo's and rebuilt the facades of some of Rome's major churches. The reconstruction of the aqueduct was finished in August 1570, with the first water flowing to a reservoir near the present Trevi Fountain.
