Ancient Park of the Aqueducts (Parco degli Acquedotti) in Rome located just outside the city on  the Appian Way. The Roman water system consisted of artificial channels for conveying water and run for some or all of their path through tunnels constructed underground. There are three Roman aqueducts which gave a possibility for Roman inhabitants to receive 1.000 liters of water per each person daily in 52 A.D.
