[5] Kangavar was mentioned by Isidore of Charax in the 1st century AD, by the name of "Konkobar" or "Concobar" (Greek: Κογκοβάρ) in the ancient province of Ecbatana (modern Hamedan).

)[7] In the early 20th century, Kangavar was held in fief by the family of a deceased court official, forming a separate government.

[9] Excavation first began in 1968, by which time the "large structure with its great columns set on a high stone platform"[10] had been associated with a comment by Isidore of Charax, that refers to a "temple of Artemis" (Parthian Stations 6) at "Concobar" in Lower Media, on the overland trade route between the Levant and India.

[citation needed] Although a general plan of the complex has been compiled, it is still not sufficient to learn about the function and shape of the terrace and the buildings that stood there.

Isidorus described obviously another temple of the first century AD, somewhere in the region of Congobar (Kangavar) or at the place of the later platform, which, according to the results of the excavation, seems to be built up in Sasanian times.
