|Summary:||Stoa; in the northeast corner of the Agora.|
|Date:||ca. 525 BC|
17.72 m x 7.18 m; Doric outer colonnade column diameter: 0.58 m; intercolumniation: 1.92 m; Doric inner colonnade column diameter: 0.42 m; intercolumniation: 5.76 m (in rebuilding decreased to 3.2 m).
Small two-aisled stoa opening east, 8 Doric columns in antis on the east, 4 Doric interior columns.
After construction ca. 525 B.C., much of the stoa was rebuilt in the 5th century, probably to repair damage suffered in the Persian invasion of 480/79 B.C. Ca. 300 B.C., 2 small prostyle wings were added. The stoa is named for the office of the king archon, who was responsible for many of the city's legal and religious matters, and copies of the law codes were displayed in the building. Immediately east of the building is the large, rectangular oath stone, 2.95 m x 0.95 m, where council members took an oath to guard the laws of the city.
