The Statue of Unity is a colossal statue of Indian statesman and independence activist Sardar Vallabhbhai Patel, who was the first Deputy Prime Minister and Home minister of independent India and adherent of Mahatma Gandhi during the non-violent Indian Independence movement.
The project was first announced in 2010 and the construction of the statue started in October 2013 by Larsen & Toubro with a total construction cost of ₹2,989 crore (₹29.89 billion; US$437 million). It was designed by Indian sculptor Ram V. Sutar, and was inaugurated by Indian Prime Minister Narendra Modi on 31 October 2018, the 143rd anniversary of Sardar Patel's birth.
Narendra Modi first announced the project to commemorate Vallabhbhai Patel on 7 October 2013 at a press conference to mark the beginning of his 10th year as The Chief Minister of Gujarat. At the time, the project was dubbed, "Gujarat's tribute to the nation".
A separate Society named Sardar Vallabhbhai Patel Rashtriya Ekta Trust (SVPRET) was formed under the chairmanship of the Chief minister, Government of Gujarat, to ensure seamless execution of the entire project.
An outreach drive named the Statue of Unity Movement was started to support the construction of the statue. It helped collect the iron needed for the statue by asking farmers to donate their used farming instruments.By 2016, a total of 135 metric tonnes of scrap iron had been collected and about 109 tonnes of it was used to make the foundation of the statue after processing. A marathon titled Run For Unity was held on 15 December 2013 in Surat and Vadodara in support of the project.
The Statue of Unity is the world's tallest statue at 182 metres (597 ft). It rises 54 metres (177 ft) higher than the previous record holder, the Spring Temple Buddha in China's Henan province.The previous tallest statue in India was the 41 m (135 ft) tall statue of Lord Hanuman at the Paritala Anjaneya Temple near Vijayawada in the state of Andhra Pradesh. The statue can be seen within a 7 km (4.3 mi) radius.
The monument is constructed on a river island named Sadhu Bet, 3.2 km (2.0 mi) away from and facing the Narmada Dam downstream.The statue and its surroundings occupy more than 2 hectares (4.9 acres), and are surrounded by a 12 km (7.5 mi) long artificial lake formed by the Garudeshwar weir downstream on the Narmada river.
The statue is divided into five zones of which only three are accessible to the public. From its base to the level of Patel's shins is the first zone which has three levels and includes the exhibition area, mezzanine and roof. The first zone also contains a memorial garden and a museum. The second zone reaches up to Patel's thighs, while the third extends up to the viewing gallery at a height of 153 metres. The fourth zone is the maintenance area while the final zone comprises the head and shoulders of the statue.
