A Hellenistic building was found at circa 1 km from the Montagna Spaccata road-cutting, along the via Campana. This new evidence for occupation of the territory before the foundation of the colony of Puteoli (194 B.C.) seems to confirm Frederiksen’s hypothesis, according to which the line of the ancient road must have pre-dated the colony’s foundation and perhaps date back to the 4th century B.C. At least five rooms were uncovered, with foundations of large parallelepiped blocks of yellow tufa. The pottery from the occupation levels and inside the collapses seems to date the abandonment of the structures to between the end of the 2nd century and the beginning of the 1st century B.C.

The same dating can be assigned to the obliteration of a large circular pit, situated close by, with steps going down into it. This may be interpreted as a pozzolana quarry, used for the construction of the settlement. It was filled with dumped earth, within the fill were two amphora burials. One was of the Dressel 1A type, datable to between 150 and 120 B.C., the other of the Maña C1 type, of Punic tradition, datable to the second half of the 2nd century B.C.
