This Seljuk fortress is located in a village with the same name, covering an area of about 2.6 hectares. Some believe the fortress was made by Sassanid and as a protection against Arab’s attack. There was an inscription on the gate, from the Safavid era that shows the fortress was reconstructed by the order of Sultan Hessam. Later Muzzafar sultan used it as a center of opposition against Safavid King. The fortress has two sections:
• Arg (citadel) – the residence of Ruler and his family (his Harem) • Armory – barracks, and military areas
The citadel was made from bricks at the western part of the fortress and in two stories. This part of the fortress has 12 entrances, springs, water reservoirs, bath, restroom, alcove, and residential units. The Armory was built on the eastern side, guardhouses were built in 2 stories and towers with holes all around to give better control of surrounding. Bath, prison, restroom, and emergency exits were all located in the eastern part of the fortress. The place is famous for its strong fortification, and the fact it has never concurred.
