Alamut

Name of a mountain fortress in northern Iran. Situated about forty-five kilometres northeast of the city of Qazwin, Alamutinfo-icon was built on the summit of an inaccessible rock in the central Alborz mountains. According to legend, an eagle indicated the site to a Daylami ruler, whence its name in the Daylami dialect, derived from aloh (eagle) and amukht (taught). The fortress was constructed by a Justanidinfo-icon ruler of Daylaminfo-icon in 860. Subsequently the area came under the influence of Zaydi 'Alid rulers. The Ismaili leader Hasan-i Sabbah seized the fortress in 1090 and made it the headquarters of his Nizari Ismaili state. The fortress became the focal point of Sabbah's challenge to Seljukinfo-icon authority in Iran. The Mongols took Alamut in 1256 and partially demolished it, also burning its famous library. It was restored under the Safavidsinfo-icon, who used it as a prison until the seventeenth century. After that, Alamut was abandoned and it was gradually destroyed by the elements and local inhabitants searching for treasures.
