This historical complex has been situated on a natural base along with unique characteristics. The complex contains the castle of Izadkhast, one caravanserai and the Safavid-period bridge. The works inside of the castle belong to different periods from Sassanids to Qajars. The most important section of the complex is the castle that has been built on singular bedrock in a sand construction and close to the valley of Izadkhast. The bedrock has protected the castle from the foreigners’ attacks. A bridge and a gate in the most accessible part of the complex made it possible to connect with the surrounding areas. The smallness of the rock led to agglomeration of built rooms. Hence, the smallness of rooms resulted in increase of floors.
