During inspections while levelling was undertaken in the development area of Fiè di Sopra, ancient occupation levels came to light. These was composed of layers of compact black and grey clays, visible in various sectors of the building site, which produced fragments of prehistoric pottery and flakes of flint. Given the potential presence of archaeological deposits, test pits were dug in the area that was still untouched by the earth movers. No ancient structures or finds appeared in the eastern sector where work is planned for the town aqueduct. Further south, low level frequentation of the area is attested by a thick dump of ancient agricultural soil, which produced artefacts datable to various periods (flint flakes, fragments of pottery which could be either Eneolithic or early Bronze Age and fragments of Iron Age pottery). Several ancient structures emerged in the southwest sector. These was composed of a wall, probably constructed on a pre-existing, possibly Roman foundation and several small dry-stone walls, consolidated in parts with clay, datable to the Iron Age. These protohistoric walls may be interpreted as foundations of structures perhaps forming the boundary of an area situated to the west, which in antiquity was used either for agriculture or as a settlement area. It is difficult to come to a conclusion about what they truly represent due to the limited extent of the excavation and the difficulty of dating the occupation level.
