The Qabrestān hill is located in the town of Saggez Ābād, in the province of Boyinzahrā (Qazvin region) and since the fifth millennium BC or even before it has been a place of abode or a cemetery.
This hill, with an area of about 10 hectares, considered one of the primordial hills of Iran, located on the plateau of Qazvin, consisted of two residential-industrial parts belonging to the Copper Age and a cemetery dating back to the Iron Age .
In this area there were some residential buildings, workshops for working with terracotta and iron. Among the characteristics of the terracotta of this region there is the extreme delicacy in the technique of realization and in the beautiful drawings traced on the surface as: motives of flora and fauna in an abstract way that demonstrate the presence of a culture and a prosperous civilization of the area .
Because of the shallow depth of the graves in this area and the fact that they are in the cultivated fields, the burials have suffered extensive damage and most of the remains of the bones of the corpses are completely rotten and can not be harvested.
It seems that almost in the period in which the settlement in the Zāghe hill ended, or around the fifth millennium BC, it began that in the Qabrestān hill.
It is one of the three primordial hills including the Zāgheh hill and the Qorreh hill (hill of Saggez Ābād); they are located at a small distance from one another and the Qabrestān hill is considered one of the oldest archaeological sites in the world.
