The 18-tonne statue is the tallest statue made of Ashtadhatu (eight metals), according to Indira Gandhi National Centre for Arts (IGNCA).
The eight metals used in its construction are copper, zinc, lead, tin, silver, gold, mercury and iron.
The statue has been sculpted by sculptor Radhakrishnan Sthapaty of Swami Malai in Tamil Nadu and his team in a record seven months.
34 generations of Mr Radhakrishnan have been making idols since the Chola Empire period.
It has been constructed using the lost-wax casting method to make finely detailed single-piece sculptures.
This process ensures there are no welded parts in the Nataraja statue.
More than 100 artists spent nearly 3.25 lakh man hours to complete the different processes involved in the lost-wax casting method to create the hollow statue.
The statue was finished at the cost of approximately ? 10-12 crore ahead of the G20 summit.
This iconic project is carried out by the Ministry of Culture team IGNCA.
