Fortifications of Mount Oneion, Corinthia

Abstract

Recent investigations on the Isthmus of Corinth by the Eastern Korinthia Archaeological Survey (EKAS) have revealed a series of relatively humble fortifications situated along the ridge of Mt. Oneion, which forms the southern boundary of the Isthmus. These Late Classical-Early Hellenistic walls, along with a nearby series of later Venetian fortifications, were designed to block access to the south through several low passes. Controlling the passage of northern armies through the Isthmus to the Peloponnese was clearly a long-term strategic concern for diverse regional powers.
