Legend has it that Kush lost his armlet, while bathing in the Saryu, which was picked up by a Nag-Kanya, who fell in love with him. As she was a devotee of Shiva, Kush erected this temple for her. It is said that this has been the only temple to have survived till the time of Vikramaditya, the rest of city had fallen into ruins and was covered by dense forests. It was by means of this temple that Vikramaditya was able to locate Ayodhya and the sites of different shrines here. The festival of Shivratri is celebrated here with great pomp and splendour.
