The ancient Gozarkhani citadel dating to the Achaemenid period entered the list of the national cultural heritage monuments. The citadel is located on a sedimentary mountain overlooking the Gozarkhani village in Firouzkouh in northeastern Tehran.

Remnants of several rooms and reservoir for food can be seen in the main part of the citadel.

The middle part of the citadel used to house guards and the army. The upper part of the citadel was where the ruler used to live.

Tens of architectural works and thousands of porcelains from the 13th, 14th and 15th centuries dot the eastern slope of the mountain atop which the citadel sits.
