"Nooshijan Hill" can be considered the oldest sanctuary of Aryans within the borders of the country, located 20 kilometers far from Malayer. Nooshijan hill is one of the unique works of the pre-Achaemenid Empire civilizations in Iran; the remnants of the third Iron Age (about 900-600 AH) and the Medes civilization. Therefore, Nooshajan hill is about 2800 years old. Nooshijan probably means "the place of drink" or "the place of Anoosh"; and "Nush or Anush" appears to be the name of a woman who ruled the area.
Nooshijan hill was identified in 1946. During the period of 1946 to 1959, excavation and restoration operations on the hill were carried out by the British Institute of Iranian Studies, led by David Stronach, during the six archaeological periods. The achievements of these activities are the identification of the three periods of ancient architecture belonging to the period of the "Medes, Achaemenians and Parthians", the most important and ancient part relates to the residence of the Med's tribes on this hill from the second half of the 8th century B.C to the first half of the sixth century B.C. The works of the two other periods are in more surface layers that have been removed after scientific studies.

Nooshijan complex is 80 meters long, 30 meters wide and the highest part is 37 meters high. Architectural artifacts related to the Median period in the Nooshijan Hill, based on David Stronach's documentation, are:

1- The old monument of the western frontier called the first fire temple

2- Columned saloons named Apadana

3- Central Temple or Second Fireplace Rooms and Warehouses

4- Tunnel

5- Fence and Fortress

Stronach believes that Nooshijan fortress was one of the defensive fortresses of the central state of Medes, built to defend western borders against the invasion of powerful Mesopotamian tribes, including the Assyrian state. The existence of two fire temples in this place confirms that in addition to military purposes, religious practices and prayers also took place in this place. Also, in Nooshijan, examples of the first human money were found, and the name of these money samples was Siglo.  The money had been made from silver, which dates back to the Medes period. The money was in the form of loops or spiral rings of silver rings and their application refers to the local geography of the Medes.
