Location of the study area. Neapolis is located halfway between two volcanic areas, Somma-Vesuvius and the Phlegraean Fields (A). The white bold line in A shows the main route of the Aqua Augusta aqueduct with its branches represented by the thinner white lines. The dotted line indicates the uncertainty over whether Pompeii was supplied by the Aqua Augusta. The black line shows the main route of the Bolla aqueduct. The archaeological excavation of the ancient harbor of Naples is located a few meters below current sea level in front of Piazza Municipio (B). Seen on the left side of the photo is the harbor dock composed of two levels: a lower level dating back to the Hellenistic period and an upper level raised in the Augustan period because of a rise in sea level. (C) An example of the harbor stratigraphic section investigated in this study and located in the eastern part of the excavation site.
