The interior of the temple is composed of a naos with a pronaos that is mirrored by the opisthodomos at the back - both distyle in antes. The interior of the naos has flanking stairways that were built into the wall which helped separate the naos from the pronaos.
The northern colonnade with the architrave and part of the frieze is completely preserved, while the colonnades on the other three sides have only survive in part. While much of the temple is intact, four columns are missing and nine severely damaged.
