The acropolis zone has been the excavation focus of the Greek team. In 2002, the southern approach to a large Hellenistic house was excavated in hopes of establishing the connection between this structure and the surrounding complex, dated to the same period. An entryway leading to a portico of the house was discovered which had been built atop older structures. Numerous other architectural elements belonging to the dwelling were brought to light which allowed the confirmation of various hypotheses concerning the presence of an upper storey and the placement of windows on the second floor.
Later excavations shifted to the areas surrounding a large Hellenistic oil mill. These were carried out in part to facilitate the setting up of a permanent structure which will cover the large building. Three probes were excavated along the east wall of the mill which revealed only partial remnants far too incomplete for synthetic interpretation. What could be determined is that these fragments represent buildings that were already in place at the location when the oil mill was built and were either demolished or reused in the construction of the mill.
More recently three trenches were opened to the east of the large Hellenistic house. Most walls found at this stage belong to structures dated to the first half of the 4th century BCE and appear to be associated with a building lying under the later mansion. One wall was certainly contemporary with the villa, although its function remains uncertain (possibly a terrace wall). Excavations at the back of the mansion were completed in 2008 and reached a depth of 10 m. Here a stele was discovered inscribed with the name of Zeus, referring to him descending in thunder and lightning, a form identical to that of a stele found nearby ten years earlier. These inscriptions are interpreted as showing the extent to which the inhabitants of Argilos were concerned with thunderbolts, thunder, and lightning.
