The entire Mandir was cut out from solid basalt bedrock, from top to bottom.
Nearly 4 lakh tons of stone was dug to create this marvel. Surprisingly no debris is found up to 100 kms radius of the Mandir. These were not made only with chisels and hammers. But advanced Ancient Bharatiya Technology was used.
The Kailasa temple (Cave 16) is the largest of the 34 Buddhist, Jain and Hindu cave temples and monasteries known collectively as the Ellora Caves, ranging for over two kilometres (1.2 mi) along the sloping basalt cliff at the site. Most of the excavation of the temple is generally attributed to the eighth century Rashtrakuta king Krishna I (r. c. 756 – 773), with some elements completed later. The temple architecture shows traces of Pallava and Chalukya styles. The temple contains a number of relief and free-standing sculptures on a grand scale equal to the architecture, though only traces remain of the paintings which originally decorated it.
