Long Walls
Long walls (analogous to the Athenian Long Walls) connecting to Nauplion were begun "circa" 421 B.C. by Athenian masons. At one point, in fear of a threatened Spartan invasion, the Argives committed unskilled men, women and slaves to work on the wall; despite these efforts, the wall was only half-completed when Argos was attacked by King Agis II of Sparta, whose men pulled down all the walls.
