Avia, Messenia

In the location where Paliochora is located today, the Homeric city of Ire (Ιρή) is supposed to have stood (Iliad I 150 and I 292). The 2nd century traveller Pausanias mentioned in his Description of Greece that the city Ire was renamed Abia by Cresphontes, king of Messene, after Abia, the nursemaid of his great-grandfather Hyllus, son of Heracles. Abia was disputed between the Messenians and the Spartans. Abia became a member of the Achaean League in 181 BCE. In the city was a temple of Asclepius. It continued to be a place of some importance down to the reign of Hadrian, as we learn from an extant inscription of that period.[4] After Pausanias' time, Abia was not mentioned in sources. It was probably destroyed during barbarian invasions.

In the early 15th century, the Venetians built the castle of Mantineia at the location of the ancient city. It was the seat of the barony with the same name. Mantineia was abandoned by its inhabitants to escape pirate raids, and they settled in the inland village of Megali Mantineia. The ruined castle town received the name Palaiochora. In 1775, the Church of the Dormition was built at the site of the temple of Asclepius.

From the mid-19th century, the inhabitants of Megali Mantineia began to settle in the beach area again, in the settlements Palaiochora, Archontiko and Kopanoi (the modern Akrogiali). Palaiochora became the seat of the community of Megali Mantineia in 1924. In 1926 both the settlement Palaiochora and the community were renamed to Avia. In 1998, the community Avia merged with 7 other communities to form the new municipality Avia, with its seat in Kampos.
