Unakoti Central Shiva Head (30-ft Bas-Relief, 8-9th c.).
Unakoti is in Kailashahar (146 km from Agartala) on a road that punishes vehicles, and most Tripura itineraries cap at Agartala+Neermahal. The site is on UNESCO's World Heritage tentative list (since 2022) but not yet inscribed, so international guidebooks treat it as second-tier.WHY NOBODY KNOWS
A rock-cut Shiva bust 30 feet tall — including a 10-foot embroidered headdress — carved directly into the cliff face at the Unakoti complex, the largest single bas-relief image in India. Datable to 8-9th century CE on stylistic grounds (Pre-Manikya rule, contemporaneous with Pala-era Bengal sculpture). The Unakoti name means "one less than a crore" (99,99,999) and refers to the legend that Shiva and a party of gods/goddesses rested here en route to Kashi; those who failed to wake at dawn were turned to stone. The central Shiva head (Unakotiswara Kal Bhairava) is flanked by Durga on a lion and a second female figure on the other side.
