About
About Aigosthena – Fortified Harbour of Megaris, Porto Germeno
Aigosthena guards the mountain pass between Boeotia and Megaris with the best-preserved 4th c. BCE walls in Greece (8 towers, SE tower 18 m tall with original roof). Harbour below SE tower preserves a 60 m mole at −1 m to −2 m and quay blocks enclosing a 1 ha basin that exported Megarian wool and Kithairon timber. The walls (2nd c. BCE, 1.2 km circuit, 2.3 m thick) in trapezoidal ashlar incorporate the harbour tower. The mole is local limestone headers with central rubble; beachrock at +0.3 m shows ~+1.3 m rise since Hellenistic. Excavated by Field (1940s) and Ober (1980s); walls restored 2011.
Why it mattersOnly Greek harbour fort with intact tower roof; shows Hellenistic border-pass harbour coupling fortification to mole.
