During work on the new high speed railway line (TAV), substantial occupation traces relating to various periods were found in the area of the “Botteghelle” viaduct. Between the 1st century A.D. and the late antique period the zone was crossed by a road.

The remains of a sanctuary (4th-3rd century B.C.) were discovered beside the road cut into the hillside in the 3rd century B.C. The earliest phase was characterized by an open area with a well and a number of pits. The fills produced numerous black glaze cups, ungentaria, fragments of terracottas and statuettes dating to the second half of the 4th century B.C. The sanctuary’s second phase was distinguished by the building of a structure in tufa blocks, perhaps a portico, delimiting an open area into which tanks, bordered by tiles placed edgeways on, were sunk. A large amount of pottery, including a cup bearing two incised letters, and coins dated to this period (4th century B.C.). In the third phase the courtyard was paved with opus signinum, while many fragments from terracottas and of black glaze pottery were recovered from a number of pits. In the last phase, towards the middle of the 3rd century B.C., the building continued to preserve its sacred function. In this phase the portico was replaced by closed room.

An ancient ground surface cultivated with parallel furrows, obliterated by the “Flegrean B” eruption, produced a notable amount of archaeological, ceramic and stone material. This was datable to the mid-late Neolithic period and related to the Serra d’Alto-Diana facies (IV millennium B.C.).

The ceramic assemblage was characterised by reel handles, depurated impasto bowls, coarse banded painted ware, ribbon handles with zoomorphic applications representing domestic animals (pigs) and simple spiral appendages. Stone working was attested by a large number of complete flint, obsidian and jasper implements.
