Frühhelladikum
Dutch excavations (University of Amsterdam) point to first settlement of the acropolis hill in the (Final) Neolithic period. In the Early Helladic period the site must have contained an administrative centre of some kind, judged by the sealing fragments that can be compared by those found in Lerna. Habitation continued towards the end of the Middle Helladic period, but no Mycenaean finds have been found yet. First signs of renewed habitation date from the Iron Age. The site is left again in the Roman period.
