Pagae, in the site of modern Kato Alepochori, was the harbor of ancient Megara at the Corinthian Gulf. The historian Thucydides refers to the strategic role of the town during the Peloponnesian War.

“...remoteness has preserved for us a Greek fortified town

in better condition and greater completeness than any other...

a place, for those who have seen it, to marvel at and return to”

The archaeological site of Eleutherai encompasses part of the lowland and rocky hill, where the ancient fortress, known as Gyftokastro, stands. Eleutherai was allegedly the birthplace of Dionysus, who founded the homonymous city and was thus called Dionysus Eleuthereus. Originally a Boeotian city, Eleutherai went over to Athens in the sixth century BC. Strategically located on the borderline of the Athenian territory, with control over the narrow passage between Athens and Thebes and overlooking the plain of Oinoe, Eleutherai was part of the Athenian defence network in the fourth century BC.

On the north slope of the peninsula, near the small Christian temple of the Holy Trinity, walls of the late archaic period are preserved, probably associated with a watchtower. During the Roman period, two Farmhouses were built in the same area. The largest of the two was set greatest on and around the archaic structure, thus he more modest farmhouse stands at the NW of the archaic structure
