Thermopylae is primarily known for the battle that took place there between the Greek forces including the Spartans and the Persian forces, spawning the famous epitaph beginning with "Go tell the Spartans". It is on the only land route large enough to bear any significant traffic between Lokris and Thessaly.

For this reason the area has been the site of several battles.

He sent two eagles flying from the eastern and western extremities, and the path of the eagles crossed over Delphi where the omphalos, or navel of Gaia was found.
