Although built in the Roman period under Hadrian (2nd century AD), the temple clearly displays Greek features. It is a pseudo-dipteral octastyle (8x15), measuring 32.96 x 36.92m. The naos is a tetrastyle prostyle, and the opisthodomos is a distyle in antis. While the outer pteroma comprised of Ionic columns, the columns in front of the naos and the opisthodomos were of the Composite order. (Video)
