The excavation area is situated at Lacco Ameno, on the island of Ischia in the Bay of Naples. Work took place in the park of the pre-existing Villa Arbusto. In antiquity, this was perhaps a suburban part of the settlement, on the slope overlooking the necropolis, close to the metallurgical centre in the locality of Mazzola. The structures of the Pithacusan settlement are at the centre of the project, that is to say, the first traces of the Greek colonists in the west and the contacts and integration of the Pithecoussai in the Mediterranean.

Thus far, two walls and a compact fill have been exposed. Wall A, running NE-SW, is built of at least three courses of large stones (foundations) and then small stones bonded with clay that could be part of the standing structure. The stones were only worked on the south face. The rear part of the wall consisted of a compact mass of small pebbles and small tile fragments. The fill was formed by large and small stones and may have formed a layer underlying an artificial terrace.

Wall B was certainly a terrace wall. It was on a higher level than wall A; it ran north-south as far as a corner and three courses of large stones survive. The pottery found in the spaces between the stones dates to the Late Geometric period (LG II).

A large amount of archaeological material was recovered during excavation and cleaning. These included tiles, impasto pottery, Greek pottery and imitation Phoenician pottery, two fragments of louteria, a loom weight, small bones, lumps of baked clay, and small iron fragments.
The new and old trenches revealed terrace walls and Greek pottery dating to between the 8th and 6th centuries B.C. To date, the finds suggest two interpretations for the area: a sacred site or residential area.
