There are such caravanserais in Iran and in many provinces of central Iran, the most important of which is the Marnjab caravanserai, which is located in Isfahan province and on the edge of the beautiful Marnjab desert.
"Manijeh Zij" or "Manijeh Castle" is one of the ancient relics left near the city of Sarpol-e Zahab, which is located 15 km from this city in a village called Patagh.
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.
