Teppe Hasanlu is an archeological site of an ancient city, located 12 km from the city of Naghade besides Hasanlu village, at a short distance south of Lake Urmia.
This is the largest site in the Gadar River valley. The site consists of a 25m high central "citadel" mound, surrounded by a low outer town, 8m above the surrounding plain. The entire site, once much larger but reduced in size by local agricultural and building activities, now measures about 600m across, with the citadel having a diameter of about 200 m.
Near the hill, there was a museum where you can see some archaeological discoveries excavated from this region.
