Hasanlu
Located in modern Iran, in the province of Western Azerbaijan to the southeast of Lake Urmia, Hasanlu is an ancient city with a long history of habitation. Since its beginnings in the 6th millenium BCE to its final abandonment in the 3rd century BCE, Hasanlu has occupied an important location along trade routes that allowed it to expand greatly in its later history. It features a citadel mound with a complex of monumental buildings, as well as a lower surrounding town with craft production areas. It is perhaps most important because it appears to have been destroyed very suddenly, preserving a great deal of material from one particular period.
