The 'Statue of Unity’ to honour Sardar Vallabhbhai Patel, India’s first deputy prime minister, will stand at 597ft when completed in 42 months, almost 100ft taller than China’s Spring Temple Buddha, the world’s current tallest statue at 502ft. It will be almost twice as high as the Statue of Liberty in New York, which is 305ft. Nelson’s Column in Trafalgar Square stands at 170ft.
