The Statue of Unity is the world's tallest statue with a height of 182 metres (597 ft). It honours Vallabhbhai Patel, one of the most prominent leaders in India's struggle for independence, and India's first Deputy Prime Minister. The statue is located on a river-island facing the Narmada Dam (also called as Sardar Sarovar dam) near Rajpipla, 100 kilometres southeast of the city of Vadodara in the Indian state of Gujarat. The monument along with its surroundings occupies an area of over 20,000 square metres (220,000 sq ft), and is surrounded by a 12 km2 (4.6 sq mi) artificial lake. It was built by Larsen & Toubro, who received the contract for US$420 million for the design, construction and maintenance in October 2014. The construction was started on 31 October 2014 and completed in mid-October 2018. It was designed by Indian sculptor Ram V. Sutar, and was dedicated by Indian Prime Minister Narendra Modi on 31 October 2018, the 143rd anniversary of Patel's birth.
