The Kailash is one of the largest rock-cut ancient Hindu temples located in Ellora, Maharashtra, India. A megalith carved out of one single rock, 164 feet deep, 109 feet wide, and 98 feet high, it is considered one of the most remarkable cave temples in India because of its size, architecture and sculptural treatment one of the biggest monilithic structures on the planet.
The Kailasanatha temple is one of the 34 cave temples and monasteries known collectively as the Ellora Caves and it has the largest cantilevered rock ceiling in the world. Its construction is generally attributed to the 8th century Rashtrakuta king Krishna I. The temple architecture shows traces of Pallava and Chalukya styles.
Archaeologists have confirmed that over 400,000 tons of rock had to be scooped out, which would have taken not years, but centuries of human labor. Historians have no record of such a monstrous task, and they think that it was built in less than 18 years.
