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.
Ghasr-e Bahram Caravansary is located in the middle of a vast plain and there are no other artificial structures around it for a relatively long distance.
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.
Morche Khort Castle is actually the old place of the village where the inhabitants lived. The existence of towers, fortifications and strong walls is due to the need for security.
