AGIOS EFSTRATIOS (Island) NORTH AEGEAN
  We have got no evidence about the period of time the castle was built - besides Agios Ephstratios has never been the object of systematic archaeological research. Except the lower parts of the wall, the reservoir of the water-supply and a trench in the east are still extant. The natives attributed it to Genoese and moreover to them they attributed the well which existed near today's school - Chora's well, as they used to call it. It was about a monumental construction with pillar all around and with a stone basin for the animals' watering.
