Many stories are popular in ancient texts about Nageshwaranath temple which is situated on the bank of Saryu River. One such story tells once the younger son of Lord Rama Kusha was bathing in the river Saryu and he lost his amulet. Kusha did a lot of effort to find the amulet but he couldn't find it. Kusha thought the reason behind losing amulet is a bad omen. This made him depressed. But, he did not know that a Nag Kanya who loved him had picked the amulet. By returning the amulet to Kusha, the Nag Kanya won his admiration. The Nag Kanya was a true devotee of Shiva, so King Kusha built the Nageshwarnath Temple at Ayodhya.
As per another belief, the temple won the test of time until the reign of Chandragupta II who was also known as Vikramaditya. But, the rest of the city was in shables. Also, the Nageshwarnath Temple had become the means by which Vikramaditya was able to locate Ayodhya and then he rebuilt the temple. The importance of visiting this temple becomes more at the time of Shivaratri as here the festival is celebrated with great pomp. If you visit Ayodhya, don't miss to visit this beautiful temple.
