Unakoti hill lies about from 178kms to the northeast of Agartala and 8 kms to the east from Kailashahar. The Unakoti hill rock cut carvings are the largest bas- relief sculptures in India. There is a huge variety of rock cut images belonging to the 11 to 12th Centauries AD, intricately carved and finely executed. It is virtually an open air art gallery. It is also a Shaiva pilgrimage dating back to the 7th to 9th Centuries AD.
Unakoti means one less than one crore. According to the legend, once Lord Shiva was going to Kashi on pilgrimage accompanied by one crore Gods and he decided to make night halt at this place. According to the story, the next morning none of the Gods except Lord Shiva woke up early in the morning to proceed on the pilgrimage. Enraged, Lord Shiva cursed the other Gods to become stone images. Hence the large number of stone carvings at this site. There is also a strong evidence of Buddhist presence at this site. There is also a central Shiva head and an imposing Ganesha statue which is 30 feet in height. The rocky wall contains carved images of Hindu Gods and Goddesses like Durga and Vishnu.
