The most magnificent castle in the Alamut Valley is the Alamut Castle, which is built on top of a high rock reaching 2163 m above sea level near the Gazor Khan Village. The rock is 200 m high and covers an area of 20 hectares (49 acres); with its steep slope and deep and dangerous ravine, the rock is practically inaccessible and forms a part of the fort’s structure. Currently, only ruins of the fort and some towers are apparent, and it is only through archaeological excavation that the main portions can be discovered.[2]
