The rocky hill of Kastron was first settled at the end of the Neolithic
era and was continuously inhabited until the 5th cent.A.D. although in the meantime
it was destroyed and abandonned for some time. The preserved structures and the
fortification date to the archaic, classical and hellenistic times (6th - 1st
century. B.C.).
The fortification walls were always visible and Korsiai are mentioned
by travelers. Excavation research was conducted in the early /80s by a canadian
archaeological mission.
The most important monuments of Acropolis of Ancient Korsiai are:
•The existing fortification walls, which protect the acropolis
and the town of ancient Korsiai. They were built in the 4th cent. B.C. Two building
phases can be discerned.
•The Temple of Hera, rectangular building to the north of the
acropolis, outside the fortifications. The earliest evidence for the cult of Hera
at Korsiai dates to the Archaic period (6th cent. B.C.).
•The so-called "industrial area" which was found on a flat terrain
to the south of the town outside the walls. What remains comprises mainly cisterns
of various sizes. Considering also the big number of weights found it is deduced
that the area was a textile workshop.
