 The remains of Heraea are visible on a hill west of the village of Agios Ioannis (St. John), bounded on either side by a ravine, and sloping down towards the river.These ruins extend along the summit of the hill and the slope towards the river; but they are inconsiderable, and have for the most part been cleared away in consequence of the fertility of the land.The wine of Heraea was celebrated in antiquity, and was said to make women fruitful.
