Alamut Castle was a Levantine Assassin fortress located in Persia, modern day Iran, during the 11th and 12th centuries. The fortress was destroyed in 1256 by the Mongol Empire, in retaliation for the assassination of Genghis Khan by Darim Ibn-La'Ahad and Qulan Gal, after which the region was abandoned.
The fortress of Alamut was, unbeknownst to the Assassins at the time, built atop the site of a small Isu temple, which contained dozens of Memory Seals. Under the leadership of Hassan-i Sabbāh, Alamut became the site of intense activity for the Assassins. During the medieval period, the castle functioned as a major stronghold for the Order, alongside the fortress at Masyaf.
By 1227, Altaïr Ibn-La'Ahad, his son Darim, the wife of his late son Sef, and his grandchildren sought refuge in Alamut, after Abbas Sofian staged a coup to take over the Assassin Order. Altaïr remained in exile in the fortress for almost two decades, during which time he made several discoveries, in addition to creating a number of inventions through the knowledge he gained from the Apple of Eden.
Altaïr also discovered the remains of the First Civilization temple, and took six Memory Seals with him, later using five of them as keys necessary to open his library underneath the fortress of Masyaf.
In 1256, Assassin control of the fortress was lost to the invading Mongol Empire, and its famous library was destroyed by fire, on the order of Ata-Malik Juwayni, a servant of the Mongol court.
- "Alamut" is a Persian word meaning "Eagle's Nest".
- It is also the name of the novel that partly inspired the Assassins Creed franchise.
