Alamut (), also called Rudbar (), is a region in Iran including western and eastern parts on the western edge of the Alborz (Elburz) range, between the dry and barren plain of Qazvin in the south and the densely forested slopes of the Mazandaran province in the north. Starting from Qazvin toward Alamut, passing through the first range of hills, curvatures, forms, are significant themes in nature's composition of this area. The famous Ismaili castle of Alamut and numerous others are in this area, which served as the heartland of the state founded by Hassan-i Sabbah.
