The ancient site of Hegmatāneh is located in the city of Hamedān (homonymous region), dates back to the Middle Ages and was built by Deioce, first king medus in the year 728 of the lunar Hegira. Some attribute its construction to Fraorte, the third king of this dynasty.
Hegmatāneh, capital of the Medes, was the summer residence of the Achaemenids and the average satrapy from the latter to the Sassanids.
This oval-shaped hill with a surface area of more than 30 hectares, with the local hill name Hegmatāneh, has other names such as: "Ekbātān (Ecbatana)" and "Qasr-e haft hesār" (palace with seven walls).
The architects of this historic city designed it and built it as seven joined fortresses and one inside the other with a particular function (the royal palace was inside the seventh) and it seems that the residential buildings of the people were close to these fortresses.
This city has walls of adobe with a diameter of about 10 meters with huge towers at specific distances, passages at equal and parallel intervals with similar and symmetrical building units.
The main structure of Hegmatāneh is built in adobe raw and some parts in brick. This complex has an entirely advanced and well organized irrigation network. The hill of Hegmatāneh in the last 100 years has been repeatedly researched by local and foreign archaeologists who during the excavations have brought to light valuable and unparalleled historical works and documents that mostly date back to the period of the Achaemenids and of their ancestors;
among these we can mention the golden plate of Arshām (part of the private collection of the American Marcel Vidal), the Āryārāmaneh gold plate (in the museum of Berlin), that of Darius II (in the archaeological museum of Iran), the golden cup (rithon with the head of a lion, in the same Iranian museum), a bowl of Xerxes, a broken jug, a plate belonging to the Achaemenid epoch and a cup, all in silver, the base of a stone column dating back to the reign of Artaxerxes II with an inscription decorated in cuneiform characters, special jars for food and water, a skeleton of human beings and many other precious finds.
The museum, which exhibits various objects of cultural and historical interest from different eras, is located at the center of the archaeological site of Hegmatāneh.
