The carvings at Unakoti relate to the Hindu pantheon. It is the largest bas-relief structure in India. The images found at Unakoti are of two types namely rock - carved figures and stone images. Among the rock cut carvings, the central Shiva head and gigantic Ganesha figures deserve special mention. The central Shiva head known as ‘Unakotiswara Kal Bhairava’ is about 30 feet high including an embroidered head-dress which itself is 10 feet high. On each side of the head dress of the central Shiva, there are two full size female figures - one of Durga standing on a lion and another female figure on the other side. In addition, three enormous images of Nandi Bull are found half buried in the ground.

The rock cut images of Unakoti include Mataikatar, or the Great God. However, a number of detached stone sculptures recovered from the site resemble the 11th- 12 century style and probably mark a change to the standard Brahmanical iconographic norms.

Every year a big fair popularly known as ‘Ashokastami Mela’ is held in the month of April which is visited by thousands of pilgrims.
