A Doric peripteral temple, 6 x 12 columns, double cella, with Ionic tetrastyle prostyle pronaos and opisthodomos. In the east cella was an interior colonnade of 6 columns, 3 on each side, dividing the cella into 3 aisles. The west cella was divided into 3 chambers, with 2 approximately square rooms at its east end leaving a 3rd, larger rectangular anteroom entered directly from the opisthodomos.
On the same location as probable earlier Geometric and late 7th century temples of Athena. This temple of 529 - 520 B.C. was damaged by the Persians in 480/79 B.C. and much of the material was reused (and is still visible) in the Themistoklean wall on the north of the Acropolis. Dinsmoor suggests that the western cella and opisthodomos remained and were used as a treasury until ca. 450 B.C. Travlos has reconstructed the pronaos and opisthodomos as distyle in antis.
