Unakoti, Archaeological site in Unakoti district, India

Unakoti is a Shaivite rock-carving site on the Raghunandan hills in Unakoti district, Tripura. Its central work is the Unakotiswara Kal Bhairava, a Shiva head about 30 feet high with a 10-foot headdress, flanked by Durga on a lion and another female figure. Nearby are three half-buried Nandi bulls and a rock panel with rows of small carved figures.

The bas-reliefs are dated on stylistic grounds to the 7th–9th centuries CE, during the pre-Manikya period, and were patronised by the Deva dynasty of Sribhumi in Samatata. The only inscription at Unakoti, on a Chaturmukhalinga image, records in 11th–12th-century Bengali characters a certain Sri Jayadeva, probably a pilgrim. The site was added to the UNESCO tentative list in December 2022.

In local Kokborok the site is called Subrai Khung, and tribal tradition credits the carvings to Kallu Gurjar, a devotee of Parvati. Each April the Ashokastami Mela draws thousands of pilgrims, with a smaller festival held in January. The only inscription, in 11th–12th century Bengali characters, names a pilgrim, Sri Jayadeva.

The site spreads across several hillsides and can be explored on foot, though sturdy shoes are recommended since paths are uneven. The best time to visit is during cooler months when the weather is drier and more comfortable for walking.
