The Archaeological site of Eleutherai (pronounced Elefthere, where -e- as in -bet-) is located by the Old National road Athens-Thebes (Athina-Thiva), right to the north of the junction to Villia. It contains part of a cultivated plain and a rocky hill on top of which the ancient fortress controls the narrow pass leading from Boeotia (Viotia) to Attica. From this point there is an unbroken view toward the ancient passage to the west and over the plain of Oinoe to the southeast. Tradition has it that the ancient city of Eleutherai was established by Dionysos, born himself there, thus given the name Dionysos Eleuthereus.
Its dating between 370 and 360 B.C. places it in the Athenian defence system that was evidently constructed along the borders of Attica during the 4th century B.C. More citadels forming this line of defense were Aigosthenion, Rhamnous and Phyle, together with watchtowers, signalling posts, temporary fieldworks and walled camps.
