It is the largest building in the Agora, 147 m wide and 17.5 m deep, oriented east-west, with Doric colonnade on each of its four sides.
It is assumed that at the two corners of the monument the intercolumniations were covered with high, thin panelling like that of the interior ionic colonnade, which separated the Stoa into two passageways of equal width
The Stoa was built o poros stone.
Only the metopes o the frieze were of marble; together with the terracotta sima they bore a painted decoration.
In the east section, steps and three column drums are preserved in their original position.
Visible at the west are its solid foundations of red conglomerate stone.
In Roman times the flat terrace at its north was used as the shortest way of crossing the Agora from east to west.
It was destroyed by fire in A.D. 267.
