This prostyle temple, (having a porticow hose columns, usually four in number, extend in a linea cross the front only), which is in Corinthian style, has 4 columns at the portico.
The temple, which has a podium, has been intact to this day as far as the eaves level. The exit steps at the front are completely ruined now. The cornices are pieredand the collapsed blocks are still in their original places. At the front is the monumental altar. The inscription copied by Sterret in 1888 reads as follows:
"His wife, the daughter of Hoplan, Anna the nun and her sons Tlaomas and Antiokhos had the temple with all its statues, stoas, workshops and ornaments built and dedicated to the semi-god emperors Zeus Megistos- Serapis."
The temple must have been built between 180-210 A.D during the Severus period.
