Aqua Augusta (Naples)

The Aqua Augusta, or Serino Aqueduct (Italian: Acquedotto romano del Serino), was one of the largest, most complex and costliest aqueduct systems in the Roman world; it supplied water to at least eight ancient cities in the Bay of Naples including Pompeii and Herculaneum. This aqueduct was unlike any other of its time, being a regional network rather than being focused on one urban centre.
