The battle was fought in a narrow pass in central Greece, where the 300 Spartans and their allies held off the much larger Persian army for three days. The Spartans fought bravely and inflicted heavy casualties on the Persians, but they were eventually overwhelmed by sheer numbers.
The Battle of Thermopylae is considered one of the most heroic battles in history, and it is remembered as a symbol of Greek courage and resistance against foreign invasion.
