Shamīrān

Shamiran is a mountain fortress in Tarom, overlooking the valley of the Qezel Uzan, the river that becomes the Safidrud farther downstream. The castle was a seat of the Justanid rulers and later counted among the fortresses occupied by the Ismailis. Its position in the rugged country between the plateau and the Caspian lowlands gave its defenders command of an important river passage.
