Nahargarh Fort was built in 1734 by Maharaja Sawai Jai Singh II, founder of Jaipur, on the Aravalli hills, as a retreat place. Nahargarh Fort is connected to the Jaigarh Fort through its fortifications. It is believed that the construction of this fort was obstructed by the spirit of a Rathore prince, Nahar Singh Bhomia. However, the spirit was pacified when a temple dedicated to him was built inside the fort. Sawai Ram Singh renovated this fort in 1868.
