Koroni was founded as Korone by Epimelidies in 365 BC who in turn came from Koronea in Boeotia.
He built it upon a still more ancient town called Asine.
The ancient town is to the south west of the modern off the Vasilitsi road (the southernmost village of Cape Akritas).
In antiquity Korone was independent and minted its own coins.
It joined the Achean league in 184 BC but was caught up in the struggle between the Spartans and native Messinians and attacked many times.
