Qaleye Dokhtar, located on the top of a high mountain, is 12 kilometers away from the west of Boshrooyeh and is adjacent to Boshrooyeh aqueduct and “Dahaneh” historical watermill. It is bound by an almost impassable precipice from three directions and can only be climbed from it southern side. This citadel has several places including wide and roofed corridors, circular garrets, halls, spacious rooms, and cisterns. It is among the healthiest citadels in this province. The main material for this building contains fine and carved rocks and a special plaster mortar. Based on its name, it was probably founded in Sassanid era but had been used in the Islamic era as well.
