Close to Megara (approximately 3 km. in the east) and 1 km. from the Byzantine church of Hagios Georgios lies the church of Hagios Demetrios. It is also cross-vaulted (like the neighboring Hagios Georgios) dated to the 13th – 14th century.
The church has undergone many modifications both externally and internally.
