The archaeological remains of ancient Hegmataneh are located in northwestern Iran. Continuously inhabited for nearly three millennia, Hegmataneh provides important and rare evidence of the Medes civilization in the 7th and 6th centuries BCE and later served as a summer capital of Achaemenid, Seleucid, Parthian, and Sasanian rulers.

Brief synthesis Hegmataneh is amongst the ancient cities of the Middle East perceived as the capital of the Medes Empire and continued to be one of the most important government seats through the Achaemenid, Parthian, Sasanian, and Islamic periods. The site's name is interpreted as taken from the term “Hangmata”, meaning “gathering place”. In ancient sources, Hegmataneh is mentioned under different names, such as “Ecbatana, Egbatana” in Greek and “Ecbatana, Ecbatanis Partierum” in Latin. Herodotus refers to a gathering of the Medes wherein Diaco (Dayukku) was appointed king.

The archaeological remains of town planning and architecture of the Parthian period, as well as the presence of artefacts made for the royal palaces in Susa and Persepolis, testify to the craftsmanship of the masters of Hegmataneh and the transfer of knowledge from Hegmataneh to other major ancient cities.
