The Bhangarh Fort is a 17th-century fort built in the Rajasthan state of India. It was built by Bhagwant Das for his younger son Madho Singh. The fort and its precincts are well preserved.
According to legend, a sadhu named Baba Balak Nath lived within the fort area, and it was his injunction that any house built in the precinct of the fort should not be taller than his own, and if the shadow of any such house fell on his, it would result in destruction of the fort town. According to another tale, a wizard adept in black magic named Sinhai fell in love with Ratnavati, a beautiful Bhangarh princess with many suitors. One day, the wizard followed her to the marketplace and offered her a love potion; however, she refused it, throwing it onto a large rock that consequently rolled onto the wizard and crushed him to death.
