In the 8th century BC, the Medes constructed a city and named it
“Hegmataneh” or “Ecabatana” which means “the place of gathering” in ancient
Persian. Hegmataneh is known as the first Capital of Iran which is related to
Deioces (Diako), the Mede king. According to Herodotus, this ancient city
including palaces, treasuries and caserns has been constructed on top of a hill
surrounded by 7 concentric high walls. The most important monument built in
Hegmataneh had been a glorious and strong palace, including seven castles in
different colors like white, blue, silver and purple. The people left their own
houses and built new ones around this giant palace.
