Dating back to the first millennium, the region was first excavated by Nassereddin Shah of Qajar dynasty.

Khorheh was for a long time believed to hold the last remains of a fire temple belonging to the Seleucids dynasty, but according to the latest discoveries, it appears to be a mansion built in the first century B.C. and used as a mansion until Arsacid dynasty.

Because of similarities to the Greek architecture foreign and domestic archaeologists reckon the place to be a temple.

According to the head of excavation group the importance of the excavation results from the unknown architect of Arsacid dynasty and the few monuments built.

The mansion consists of two interior (seraglio) and exterior parts separated completely by a door, signifying the main architectural significance of the Arsacid dynasty.

The exterior part of the mansion was used for formal visits and gatherings, and family members used to live in the interior part of the building.

The edifice was also used in the Sasanian dynasty and later turned into a symmetry in the Ilkhanid era.
