According to the Kalika Purana, in the beginning of the creation Siva sprinkled ashes (bhasma) at this place and imparted knowledge to Parvati (his consort).

The presiding deity of the temple is Umananda (Tatrasti bhagavan sambhu- ruma- nandakarah Prabhu).

The surroundings of the temple and the divine but understated beauty of the island make it a haven for nature lovers.

Brick temple of Umananda was built in 1694 CE by the Bar Phukan Garhganya Handique by the order of King Gadadhar Singha (1681–1696), one of the eldest and strongest rulers of the Ahom dynasty.

Later, it was reconstructed by a rich local merchant who chose to inscribe the interior part of a Siva temple with Vaishnavite slogans.

[2] The temple has inherited some rock-cut figures, which speak passionately of the masterly skill of the Assamese craftsmen.

Representations of Surya, Ganesha, Shiva and Devi (with a scorpion as emblem) in addition to those of Visnu and his ten incarnations (avatar) are found here.
