Ancient Greece - Peloponnesian War

While not technically within Sparta, Acrocorinth, the fortified citadel of Corinth, was crucial during the Peloponnesian War because of its strategic location. This significant fortress played a vital role in defending the Peloponnesian League against Athens, serving as a critical point to control access between the Peloponnesian coast and the rest of Greece.
