Alamut is a medieval mountain fortress complex in Qazvin province, Iran, notable as the headquarters of the Nizari Ismailis during the medieval period. The site survives as a series of ruins perched on a steep rock above the Alamut Valley.

Visitors encounter the remains of defensive walls, foundations, water cisterns and terraced outworks on the rocky spur that once held the castle. The site offers hiking approaches through the valley and views across the surrounding Alborz foothills.

The fortress was captured by Hassan-i Sabbah in 1090 and became the principal stronghold of the Nizari Ismailis until the mid-13th century. It was dismantled during the Mongol campaigns of 1256, after which the site fell into ruin.

Alamut sits in the Alamut Valley in the southern Alborz mountains of Qazvin province in northern Iran. The ruins are set above a steep valley landscape and are accessed by local roads and mountain trails.

  • Nizari Ismaili headquarters: Seized by Hassan-i Sabbah in 1090, the site served as the main stronghold of the Nizari Ismailis during the 11th to 13th centuries.
  • Destruction by the Mongols: The fortress was destroyed in 1256 during the Mongol campaigns that dismantled many regional strongholds in the Alborz mountains.

What to See #

  • Alamut Castle (ruins): The ruined hilltop fortress complex includes surviving stone walls, foundations, cisterns and terraced outworks positioned on a rocky spur above the valley. Much of the visible fabric today dates from medieval repairs and Nizari Ismaili occupation.
  • Alamut Valley: The Alamut Valley itself is a steep, often forested valley in the southern Alborz mountains that contains the routes and trails used to approach the fortress. The valley remains a primary context for visits and treks to the ruins.
