The first aqueducts were built in the early second millennium B.C. and are from the Minoan civilization on Crete and Mesopotamia. The earliest sophisticated, Roman-style aqueduct was constructed in the ninth century B.C. by the Assyrians.
Roman aqueducts are one of the marvels of the ancient Roman world. Arched aqueducts were located all over the Roman empire, supplying running water for drinking, indoor plumbing, public baths and decorative fountains. The total length of all the aqueducts in the empire was over 250 miles. Aqueducts were a vital part of the ancient Roman water system, a system that has not been surpassed in capability until modern times.
