Castle has rampart and some towers and has some spaces such as room of soldiers, food storage, water reservoir, etc. The foundation of castle is established during Sasanide era and was bought and repaired by Ismailia during 5th and 6th centuries of Hegira. The castle is one of the castles in the 6th and 7th centuries and belongs to Ismailia but there is a significant difference between this castle and other Ismailia castles. It enjoys two architectural methods of aristocratic buildings and ordinary buildings. The castle is highly important because it can be a very efficient pattern to study architecture and social relations in an urban-based group habitat.
