The Indian Emblem of India is the symbol of the Republic of India, formally called 'National emblem'. It has four lions. The idea for this coat of arms was taken from the Sarnath Lion Capital that was built by Indian emperor Ashoka. It's a pillar in the city of Sarnath. Ashoka built it around 250 BC using a single piece of polished sandstone. The symbol is invariably used on all types of currency notes, passports and coins of India. In the two dimensional view of this symbol, one can see 3 heads (the fourth being hidden from view). It was adopted on 26 January 1950, the day that India became a republic.
