Last year, archaeologists started their excavations in the historic Ecbatana (Hegmataneh) hill in Iran's Hamedan province, looking for evidence of Median civilization which is believed to have populated this area sometime between 728 BC and 550 BC. Instead, excavations in the lower layers of this hill resulted in the discovery of a number of historic remains which archaeologists believe to have belonged to the Parthian Empire (248 BC–AD 224) and surprisingly no single evidence from the Medians was found, making archaeologists suspicious of the existence of the Medians in this hill at all.
