The ancient city, known as Xarab-I Kilashin was discovered on Monday as part of a major archaeological research which started back in 2012, BasNews reported, adding that the research covers an area of 3,000 square kilometers.
One of the expedition leaders, Rafał Koliński, told IBTimes UK that the archeological team was surprised by the size of the settlement as most other ancient cities discovered around the same area are considerably smaller in size.
Xarab-i Kilashin is arranged in a semi-circle stretching for a diameter of about 300 meters, said Koliński who works at the Institute of Archeology at the Adam Mickiewicz University in Poznań.
The expedition is expected to continue researching the area on both banks of the Great Zab River, 50 km north of the Kurdistan Region's capital city, Erbil. Around 12,000 artifacts were discovered, including pottery and terracotta stamps used mainly for decorating tissues.
For many years the Kurdistan region was an off-limits territory for archaeologists, mostly because of political instabilities in the past, but also due to the presence of the so-called Islamic State (IS).
