Aegosthena, settlement and fortified place in the territory of *Megara, at the easternmost point of the Corinthian Gulf. The remnants of the Spartan army which was defeated at *Leuctra joined a relieving force at Aegosthena on their way back to Sparta (Xen. Hell. 6. 4. 26). The fortifications are (despite earthquake damage in the early 1980s) among the best preserved in Greece, but the history of the site is ill known, and their date is uncertain: they were probably not much, if at all, before 350, but may be 3rd-century. Aegosthena went into the *Achaean Confederacy when Megara joined in 243/2 bce, and over to *Boeotia in 224; it remained Boeotian when Megara returned to Achaea. Under Rome it was an autonomous *polis. See fortifications (Greek).
