Stoa of Zeus Eleutherios
Lying just south of the railroad tracks, along the west side, are the remains of the Stoa of Zeus Eleutherios (Freedom) (Figs. 8, 9). This cult of Zeus was established after the battle of Plataia in 479 B.C., when the Greeks drove the Persians out of Greece.
Though dedicated to a god, the building takes the form commonly used for a civic building: a stoa (colonnade or portico), with two projecting wings. Built of marble and limestone in the years around 425 B.C., the stoa had Doric columns on the exterior and Ionic columns within. According to Pausanias it was decorated with paintings done by Euphranor, a famous 4th-century artist, and the shields of those who died fighting for the freedom of Athens were displayed on the building. Rooms were added to the back of the stoa in the Early Roman period and may have housed a cult of the Roman emperors.
