What does the name 'Thermopylae' mean in English?

What does the name “Thermopylae” mean in English? It means “Hot Gates.” The name comes from the Greek words thermos, meaning “hot,” and pylai, meaning “gates” or “passes.” It refers to the area’s hot sulfur springs, which still exist near the modern site in central Greece.

Thermopylae was not simply a battlefield name. In antiquity, it was a narrow coastal passage linking northern and central Greece. Because the route was hemmed in by steep mountains and the Malian Gulf, a relatively small defending force could block a much larger army. That geography explains why Leonidas and his Greek allies chose it as their defensive position in 480 BC.

The phrase also carried mythological associations. Greek tradition connected the “gates” with an entrance to Hades, the underworld. One myth said that Heracles used the area’s waters while trying to cleanse himself after being poisoned by the Hydra; the waters were said to have become hot as a result.

The ancient pass has changed substantially. Sediment deposited by the Spercheios River has pushed the shoreline several kilometres away, so the landscape visitors see today is broader than the narrow passage defended in the battle.
