Where is Hasanlu?
Teppe or Tappeh Hasanlu is one of the important archaeological site of Iran. It is counted as an ancient city located in northwest Iran (in the province of West Azerbaijan), a short distance south of Lake Urmia. The nature of its destruction at the end of the 9th century BC essentially froze one layer of the city in time, providing researchers with extremely well preserved buildings, artifacts, and skeletal remains from the victims and enemy combatants of the attack.
Hasanlu Tepe is the largest site in the Gadar River valley and dominates the small plain known as Sulduz. The site consists of a 25 m high central "citadel" mound, with massive fortifications and paved streets, surrounded by a low outer town, 8 m above the surrounding plain. The entire site, once much larger but reduced in size by local agricultural and building activities, now measures about 600 m across, with the citadel having a diameter of about 200 m.
The site was inhabited fairly continuously from the 6th millennium BC to the 3rd century AD. It is famous for the "Gold Bowl" found by a team from the University of Pennsylvania led by Robert Dyson.
