|Summary:||Two-aisled stoa; in the northwest corner of the Agora.|
|Date:||ca. 425 BC - 410 BC|
43.56 m x 10.73 m; projection of wings: 5.86 m; width of wings: 10.6 m. Doric outer column diameter: 0.79 m, intercolumniation: 2.01 m (wings), 3.02 m (center); Ionic inner column diameter: 0.69 m, intercolumniation: 6.04 m.
Doric exterior, Ionic interior with projecting wings at both ends. Opened to the east.
Dedicated to Zeus Eleutherios (Freedom), a cult founded after the Persian War. It was unusual for a religious building to take the form of a stoa rather than a temple, and considering its central location it is likely that the building also served other civic purposes. Possibly one of the accomplishments of Mnesikles, the architect of the Propylaia.
