2(r): The Claudian Aqueduct (Aqua Claudia), completed by the Emperor Claudius, 41-54 AD was one of nine aqueducts of imperial Rome. It was remarkable for the quantity of water it conveyed to the city and was by far the grandest in terms of architectural effect, running for about six miles before it reached the city as a continuous range of lofty arches up to 33 meters (109 ft) high.
