|Summary:||Temple; at the western end of the Sanctuary of Amphiaraios.|
|Date:||ca. 300 BC - 200 BC|
Doric temple, hexastyle in antis with a cella opening northeast onto the pronaos. Inside the cella, 3 aisles created by 2 rows of columns, 5 columns to a row. At the rear of the temple a door led to a small adyton.
The temple replaced an earlier, smaller one just to the north, on the terrace where later dedications stood. Immediately in front of the temple were the altars, a sacred spring and a curved seating area (probably for attending ceremonies). Dinsmoor reconstructs the temple with a two-columned rear entrance instead of an adyton.
