Nahargarh Fort, formerly known as Sudarshan Garh is situated 6 km north west of the city, atop Aravalli hill at an elevation of 600ft . The fort was originally built in 1734 by Jai Sawai Singh and later further additions were made to it by the succeeding rulers. The name Nahargarh (means the abode of tigers or tiger fort) is derived after the death of Rathore prince, Nahar Singh. It is said that the spirit of the prince used to haunt the site during the construction and in order to please the spirit the fort was named after him. The fort was extended in 1868 and in 1880 it was altered as a monsoon retreat by Maharaja Sawai Madho Singh. At present a great part of the original structure are in ruins, but the new additions added to the fort in the 19th century by Sawai Ram Singh II and Sawai Madho Singh II are well-preserved. The fort offers a breathtaking view of the surrounding area, especially the Mansagar lake and the Jal Mahal Palace. The fort is open daily from 10a.m to 6p.m.
