The building, with 20th century anastylosis, measures 67 x 25.34 m, with a peristais of 6 x 15 Doric columns and a cella with pronaos and opysthodomus, is located over a three-step basement. It is the first example (later become common in the Agrigento temples) of pylons inserted between the pranos and cella, housing the stair which allowed inspections of the roof. The columns are rather high and have wide capitals. On the eastern side are remains of the large altar.
