Thermopylae

Thermopylae (Greek, “hot gates”), narrow mountain pass that in ancient Greece led from the north to the south. This pass between Mt. Oeta and the Maliac Gulf was the scene of a famous battle from the Persian Wars (480 B.C.) that the Spartans lost against the invading Persian forces. Although this area is a marshy plain rather than a mountain pass, it contains hot springs as it did in ancient times.
