The Kailasa Temple, Ellora caves that can never be built once again on Earth !!The largest Monolithic Structure of the World. 164 ft long, 108 ft wide & 100 ft high, Entire Temple from top to bottom was cut out from solid basalt bedrock!These were not made only with chisels & hammers. But advanced Bharatiya Technology was used. Lots of knowledge was lost in the burning of Nalanda University...!!
