The name Agnigarh suggests a fire fort. People often come here for picnic or simply to enjoy the scenes and sights. There is a very famous legendary story behind this place. This renowned mythological place is connected with the romance of Prince Aniruddha and Princess Usha. Aniruddha was the grandson of Lord Krishna, whereas Usha was the daughter of Banasura, the famous Asura king and prime devotee of Lord Shiva. It is believed that Agnigarh is the very place where a fortress was built by the Asura king, to keep his daughter in isolation. Currently Agnigarh is present in Tezpur in the form of a small hill facing River Brahmaputra. This hill provides a complete view of the city. It is also surrounded by a clean and green park displaying certain sculptures related to the couple along with giant mushrooms and a waterfall.
