 An ancient settlement, which survived until early Byzantine times, was located on the southern coast of the Bay of Pteleos near the modern village of Achilleion, where a mosaic floor and remains of two early Christian basilicas have been found.The medieval settlement was located on the northern part of the Bay, near the modern village of Pigadi, and is attested for the first time in 1192, when "wine from Pteleos" (οἶνος Πτελεατικός) is mentioned as being traded in Constantinople.After the Fourth Crusade (1204), the area passed under the control of the Frankish Kingdom of Thessalonica, but in 1218 it was recovered by the Despotate of Epirus.
