One of the important caravanserais located in Semnan province and south of Garmsar is "Ain al-Rashid" which is located a short distance from Ghasr-e Bahram caravansary.
The castles of Bandar Langeh region were generally built for the life of local rulers. Kalat Castle was also built for the life of Sheikh Suleiman al-Hammadi.
Entering the castle requires a half-hour walk and you have to climb the mountain. Parts of the route are a bit difficult and not suitable for children and the elderly.
