Mehrnegar Castle

Mehrnegar Castle, also known by its old name "Mehrin", stands in Semnan Province, in the mountains north of Damghan. It lies along the Cheshmeh Ali road, between the villages of Astaneh and Ahuanu. The castle was built on top of the region's rocky heights, and its mountain location and wide views over the surroundings meant it was long used as a strategic base. The exact date of construction is unknown, but because its location and structure resemble those of other mountain fortresses, it is thought to have been one of the strongholds associated with the Ismailis.

Today the structure of Mehrnegar Castle survives only as remains of stone walls and buildings, yet even these show its military and lookout importance in the past. Its position on a route linking the mountain areas, close to attractions such as Cheshmeh Ali, made the area a place for passing through and controlling important routes. The setting around the castle, with its high mountains, natural valleys and the green garden lanes of the surrounding villages, creates a very beautiful landscape that combines history and nature.

To reach Mehrnegar Castle, drive from Damghan towards the Cheshmeh Ali road, and once you reach the area of the Astaneh villages, continue on foot as a hike. The visit and hike usually take about one to one and a half hours. The best times to visit are spring and autumn, when the weather in the region is more favourable. Because the castle sits in a natural, mountainous environment, it is very important to follow the principles of responsible nature tourism and keep the area clean.
