13. Thermopylae Pass
The Thermopylae Pass is a narrow mountain pass in central Greece, renowned for the Battle of Thermopylae in 480 BCE. During this battle, a small Greek force, including 300 Spartans led by King Leonidas, held off a much larger Persian army for three days. The pass’s strategic location made it a critical chokepoint in Mediterranean history, exemplifying the significance of controlling narrow passages in warfare. (worldhistory.org)
