PM Narendra Modi inaugurated the Statue of Unity or Sardar Patel’s statue, the world’s largest statue, on the statesman's 143rd birth anniversary in Gujarat. The statue has been dedicated to Sardar Vallabhbhai Patel, fondly known as the Iron Man of India. The statue stands in the midst of the Narmada River, on the islet of Sadhu Bet. Sardar Patel is credited for unifying all of the 562 princely states in pre-independence India to form what is today the Republic of India. The statue is made up of 1,700 tonnes of bronze, 1,850 tonnes of bronze cladding, 70,000 metric tonnes of cement and 24,500 metric tonnes of steel.
