Naples and Its Waters: A 2700-Year History
Neapolis and the Aqua Augusta Aqueduct:
The Aqueduct in the Territory of Neapolis
From the branching point for Atella, the aqueduct ran with a minimal slope along a long straight path under the current location of Naples Airport, following the direction of the modern runway. It emerged with a small aqueduct bridge, no longer in existence, in a section of the current Calata Capodichino and then with another aqueduct bridge, the remains of which are known as the "Ponte Rossi" (Red Bridges). After the Ponti Rossi, the course of the aqueduct approached Neapolis, passing under a corner of the current Botanical Garden, emerging with a short aqueduct bridge at the height of Via dei Vergini, and skirting the northwest corner of the city walls.
It then, maintaining the necessary elevations, headed towards a point in front of the ancient Palepolis (Partenope), running along the side of the hill above present-day Mergellina, towards the hill that separates Neapolis from the next plain (Fuorigrotta), reaching it with a tunnel different from the famous Neapolitan crypt but parallel to it.
At the northwest corner of the walls of Neapolis, the aqueduct grazed the walls, and from there, a branch of the aqueduct serving the upper part of Neapolis originated. Remains of a cistern have been found in that area, which, due to altimetric reasons, could not have been served by the Bolla aqueduct.
Further ahead, in the upper part of Via Tarsia, the remains of a cistern were found, likely fed by a second derivation serving the lower part of Neapolis.
In front of the Palepolis hill, a third derivation began, reaching the ancient center necessarily via an aqueduct bridge. Remains of conduits have been found in Piazza Santa Maria degli Angeli.
Just before the tunnel leading to Fuorigrotta, there was a secondary branch running along the Pausylipon (Posillipo) hill, serving the wealthy villas in the area up to the famous residence of Publius Vedius Pollio near the islet of Gaiola.
Immediately after the tunnel, another secondary branch ran along the side of the hill to reach, with an aqueduct bridge over the sea, the islet of Nisida, where the luxurious residence of Lucullus was located.
After the tunnel, the aqueduct ran along the sides of the hills north of the plain of Fuorigrotta, passing near the thermae of Via Terracina and the thermae of Agnano, and then along the hills overlooking the sea until reaching Puteoli.
