Archaeological artefacts demonstrate that the village district has been continuously occupied from the Roman and Byzantine periods to the modern era. Protected archaeological sites are located at the sites of Paleokastro and Gournarakia.
The village area of Petroto in the Argithea region was said to be inhabited by the ancient Pelasgians, and later settled by the Athamanens. The region was also once a settlement of the ancient Alopians and Ethiopes who were vanquished by the army of the Roman Empire.
