An ancient royal city that once served as a fortress may have been re-discovered nestled in a Middle Eastern mountain range.
Archaeologists believe the lost city of Natounia in modern-day Iraqi Kurdistan could be among the excavations and aerial mapping carried out on the fortress of Rabana-Merquly, a major centre of the Parthian Empire some 2,000 years ago.
Until now, the only evidence of the city came from text on a handful of coins dating back from the first century BC found in modern-day Nusaybin in Turkey.
