vestiges of a castle built in the centre of the village of Psinthos. The visible ruins of a two-storey building with ground floor vaults were part of a larger defensive complex whose building material -and possibly another part- have been incorporated into the structure of the neighbouring parish church a few yards to the north. Although the present state of the ruins and the lack of systematic research cannot allow further discussion, it is probable that the castle's function was the protection and control of economic activity in a particularly fertile agricultural area.
