Thermopylae

Thermopylae ( /θərˈmɒpɨliː/; Ancient and Katharevousa Greek Θερμοπύλαι, Demotic Θερμοπύλες: "hot gateways") is a location in Greece where a narrow coastal passage existed in antiquity. It derives its name from its hot sulphur springs. "Hot gates" is also "the place of hot springs and cavernous entrances to Hades".

Thermopylae is primarily known for the battle that took place there between the Greek forces including the 300 Spartans and the Persian forces, spawning the famous epitaph beginning with "Go tell the Spartans". It is also the locality of the city Anthela (Ἀνθήλη), where the first Amphictyony is mentioned.
