Nahargarh Fort is an 18th-century fort in Jaipur, Rajasthan, built by Maharaja Sawai Jai Singh II in 1734 for defending the city. Originally named Sudarshangarh, it was renamed to honor the spirit of Nahar Singh Bhomia. It is known for its unique water harvesting system, including step wells, and was once a royal retreat for the queens. Today, the fort is a popular tourist destination, featuring a wax museum, and is famous for its views of the city, especially at sunset.
