There are mainly three tales regarding the establishment of Unakoti hill. The first is, once Lord Shiva was travelling to Kashi with many gods and goddesses and sleepover here on the way. The next morning, none except Lord Shiva woke. Angered by this, Lord Shiva petrified all except himself. Second one is about a mad sculptor, Kallu Kumar. He wanted to go to Kailash and for that Lord Shiva asked him to sculpt 1 crore deities overnight. By dawn, he had carved one short of crore and thus left back on earth. The Last story also concerns Kallu Kumar. By Lord Shiva dream order, Kallu sculpted 1 crore deities, with the last one being himself. Angered by his arrogance Lord Shiva punished him by not rewarding him.
Traveling to Unakoti hill is easy from Agartala, Tripura or Silchar, Assam.
