💡 Did You Know…?
Legend has it that the name Eurialo derives from the pointed shape of the rock, similar to a nail (in Greek ‘eurialos’). During excavations, catapult projectiles and remains of war machines were found, concrete testimonies of the sieges it endured. The central cistern, still visible, ensured water supply during long sieges. A little-known detail: some tunnels were so narrow that only one person could pass through at a time, making the defense even more effective.
