The medieval Rudkhan Castle (Ghale Roodkhan) is located 25km southwest of the city of Fooman in Iran’s Gilan Province in the heart of the forest. Made from brick and stone, the castle covers 50,000 square meters and is 900 meters above sea level. Its architects have benefited from natural mountainous features in the construction of the fort. It is built on two tips of a mount with a total of 65 towers surrounding it, while the walls run 1,500 meters in length. 42 towers still stand intact. It is a military complex which had been constructed during the Seljuk Dynasty by followers of the Ismaili sect. The castle sits at the two peaks of a mountain at elevations of 715meters and 670meters, with an area of 2.6 hectares (6.4 acres). The Rudkhan Castle River originates in the surrounding heights and flows from south to north. It takes around two hours to cross a mountainous winding route with dense forests. To reach this castle people walk a three kilometer distance on foot, then climb around 2,000 steps. The first thing that one notices about the castle is its big entrance gate.
