In the territory of Caivano an investigation was made of a small late antique necropolis, obliterated by the so-called “Pollena” eruption of Vesuvius. The cemetery comprised adult burials in “a cassa” tombs of tiles or tufa flakes, with grave goods represented by single handed small jugs and lamps with beaded discs (4th century A.D.) The adult burials were associated with infant burials in amphorae of the African I and Almagro 51 A-B types. The tombs belonged to a villa of which three sections of opus caementicium wall were identified. These had been obliterated by the necropolis and then by the eruption. The earliest materials were found in the southern part of the investigated area and suggest that occupation of the site began around the mid 1st century A.D. The most important evidence for the Republican period was constituted by a network of drainage channels and ditches relating to agricultural activity. One of these was filled with largely domestic materials dating until the beginning of the 1st century B.C. As regards the prehistoric levels, the site appeared to have been intensely occupied in the final phase of the middle Bronze Age (15th-16th century B.C.), as attested by the abundance of pottery fragments found in the wells. Extensive similar evidence recovered in the lot to the north suggest the presence of a village in the vicinity. The early Bronze Age phase was better articulated. A ditch, probably used as a drainage channel for surface water, and five circular pits (diam. 1.70 m) were identified. Animal bones and whole vases, deposited according to a ritual that is often seen on other sites in the same zone, were found on the bottom of the wells.
