Alamut Castle

Alamut (Persian: الموت‎, meaning "eagle's nest") is a ruined mountain fortress located in the Alamut region in the South Caspian province of Qazvin near the Masoudabad region in Iran, approximately 200 km (130 mi) from present-day Tehran.In 1090 AD, the Alamut Castle, a mountain fortress in present-day Iran, came into the possession of Hasan-i Sabbah, a champion of the Nizari Ismaili cause in 1090 AD. Until 1256, Alamut functioned as the headquarters of the Nizari Ismaili state, which included a series of strategic strongholds, scattered throughout Persia and Syria, with each stronghold being surrounded by swathes of hostile territory. Alamut, which is the most famous of these strongholds, was thought impregnable to any military attack and was fabled for its heavenly gardens, library, and laboratories where philosophers, scientists, and theologians could debate in intellectual freedom.The stronghold survived adversaries including the Seljuq and the Khwarezmian empires. In 1256, Rukn al-Din Khurshah surrendered the fortress to the invading Mongols, who dismantled it and destroyed its famous library holdings. Though commonly assumed that the Mongol conquest obliterated the Nizari Ismailis presence at Alamut, the fortress was recaptured in 1275 by Nizari forces, demonstrating that while the destruction and damage to the Ismailis in that region was extensive, it was not the complete annihilation attempted by the Mongols. However, the castle was seized once again and fell under the rule of Hulagu Khan’s eldest son in 1282. Afterward, the castle was of only regional significance, passing through the hands of various local powers.
Today, it lies in ruins, but because of its historical significance, it is being developed by the Iranian government as a tourist destination.
