Perhaps the main reason for heading to Salamína is for the boat trip itself, through an extraordinary industrial seascape of docks and shipworks. The waters you cross were the site of one of the most significant sea battles of ancient times; some would say of all time, given that this was a decisive blow in preventing a Persian invasion and allowing the development of Classical Athens, and with it modern Western culture.
In 480 BC, the Greeks were in full retreat from the vast Persian army under Xerxes, following the defeat of the Spartans at Thermopylae. Many Greek cities, including Athens, had been sacked and burned by the invaders – indeed smoke from the ruins on the Acropolis probably formed a backdrop to the Battle of Salamis. The Greeks had roughly 370 triremes supplied by around twenty cities, the bulk from Athens, Corinth and Aegina; the Persian fleet was twice the size, with heavier ships, but even more diverse, with many from subject nations whose loyalty was questionable.
Through false information and strategic retreats, the Greeks managed first to tire many of the Persian crews – who rowed all night to cut off a non-existent escape attempt – and then to lure them into the narrow strait off Salamína. Crowded in and unable to manoeuvre, and with the wind in the wrong direction, the Persians found themselves at the mercy of the more nimble Greek triremes, and the battle eventually became a rout. Some two hundred Persian ships were sunk, against forty-odd on the Greek side, and few of their heavily armoured crews or marines survived.
