On the slopes of Mount Tangab and Near the Tizreh river, a castle was built to defend the Sassanian cities against enemies, which called Qal'eh Dokhtar.
Qal'eh Dokhtar is located near the Firuzabad city of Fars province. This castle was a defensive fortress and a significant obstacle to prevent the enemy from crossing the Tangab valley. Qal'eh Dokhtar was built on King Ardashir's I order, the founder of the Sassanid dynasty in 224 AD. He built this castle before the war with the Parthian King, Artabanus V, and to dominate Fars.
The shape of the castle is Trapezoid. The area of Qal'eh Dokhtar is about 2,300 square meters and made of rubble, chalk, and Sarooj. Qal'eh Dokhtar has a dome that designed unique, but now a little bit of it remains. There is a cave in this castle. In line with what had been said, this cave was linked Qal'eh Dokhtar to Palace of Ardashir to receive essential supplies and soldiers at the imprisonment time. This castle is made up of three levels. After entering the castle, there is a spiral staircase that leads to a courtyard. There are two yards in this castle. In the upper yard, there is a part called Mahtabi.
