“...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”  

                                                                                E.F. Benson, 1895

Habitation continued into Early Christian times, as evidenced by the 5th century BC five-aisled basilica in the lower town of the fortress of Aigosthena. In the 11th century the chapel of Virgin Maria or Agia Anna was built over the ruins of the basilica of ancient building material.

The Church of Agios Athanasios belongs to the architectural type of the simple four-column cruciform inscribed domed church. The dating of the fresco of Agia Kyriaki in the first half of the 13th c. provides an ante quem dating of the monument.

During the Byzantine and post-Byzantine period, the area of the acropolis of the Fortress of Aigosthena hosted the Monastery of Agios Georgios, from which the ruins of monks are preserved, as well as the katholikon, dedicated to Agios Georgios.

The Church of Agios Georgios is located at the site "Orkos" or "Abatzades" in Eleonas, very close to the tunnels of the ancient aqueduct that fed the "Fountain of Theagenes", in the city of Megara. The church dates back to the 12th century and today survives in a semi-ruined condition.

The Church of the Metamorphosi Sotira, in Eleonas of Megara, known to the local community as "Christos", is the most important and best-preserved Byzantine church in the wider area of the city of Megara.

The Eleonas of Megara is spread out overgrown with centuries-old olive trees, among which are still preserved the Byzantine churches of Eleonas that the travelers of the 17th century saw on their journey.

«Returning to Megara, we took our horses and went three or four miles north,
to a ruined town called Paleochori, where we saw six or seven churches,
built, as I found out, from the ruins of some older buildings.
In there we found ancient inscriptions»
