Stoa Amphiaraion (also known as the Enkoimeterion) is located on the east side of the Sanctuary of Amphiaraios, southeast of the Theatre.
Before its destruction, two small rooms were separated from the rest of the stoa by two columns with a screen between them and a bench running the length of the back wall.
Pilgrims would migrate to the stoa and sleep there, awaiting an oracle's advice.
This stoa likely replaced an existing one, located further southwest on the terrace where the later row of dedications stood.
