World's tallest statue '' Statue of Unity'' in honor of Indian patriot Sardar Patel,

Patel's statue -  ‘Statue of Unity’ on Sadhu Bet Island, Gujarat .en.wikipedia.org
The Statue of Unity , the world's tallest statue is a  deserving tribute to the Indian statesman and founding father, Sardar Vallabhbhai Patel (1875–1950) in the state of Gujarat, India. With a height of 182 metres (597 ft), it is located on a river island - Sadhu Bet Island near the Sardar Sarovar Dam on the river Narmada in Kevadiya colony, 100 kilometres (62 mi) southeast of the city of Vadodara. This giant statue was dedicated to  the nation on 31 October 2018 by PM Modi who was the brainchild behind this mammoth project. While CM of Gujarat Mr. Modi made an announcement about this project on 10 October 2010. The statue and its surroundings occupy more than 2 hectares (4.9 acres), and are surrounded by a 12 km2 (4.6 sq mi; 3,000 acres) artificial lake formed by Garudeshwar dam on the Narmada river downstream. The total project cost was around Rs. 2980 crores

An interesting fact is this huge project was completed within a short span of time -mere 33 months - indeed, a world-record-breaking time. Majestically standing above the quiet waters of the Narmadha river, PM Modi's long-cherished vision was made into reality by the Sardar Vallabhbhai Patel Trust (SVPRET) and Sardar Sarovar Nigam Ltd (SSNNL) by following innovative engineering techniques and to surmount the challenges. With the spirit of dedication  and right approach, they overcame the hurdles and made this statue a unique one  in the world. A true honor to a great freedom fighter, befitting his tall stature and and dedicated patriotic role in India's freedom struggle against the wily British.

Patel's statue is twice the height of the Statue of Liberty  on the Liberty Island off New York. Surprisingly, 210000 cubic meters of concrete, 6500 tons of structural steel, 18500 tons of re enforcement steel, besides 1700 tons of bronze went into the construction of this statue. Yet another interesting feature of this statue is  there is a viewing gallery at 134 meters high above the ground and it can accommodate 200 people at a time. This is not tried in any giant statues in India before. Two express elevators are in service to take the visitors to the top and base.  The statue is built to withstand winds of up to 130 kilometres per hour (81 mph) and earthquakes measuring 6.5 on the Richter scale. This is aided by the use of two 250-tonne tuned mass dampers which ensure maximum stability.  It was designed by a well-experienced Indian sculptor Ram V. Sutar.

Known as the architect of independent India, Patel played played no less role in freeing India from the oppressive British rule. He was solely responsible for building a united India by undertaking the most difficult job - integrating more than 550 Princely States who had an option to join either the Indian Union or Pakistan or remain independent. PM Modi said, '' The Statue of Unity (of Patel) is a symbol of both the unity of heart and geographical  integrity of our mother land.It is a remainder that  divided, we may not be even able to face ourselves. United, we can face the world and scale the heights of growth and glory .... He saved India from Balcanization."

Armed with political acumen, integrity and good administrative skill, never had Patel failed to pay due attention to the poor and marginalized people. As he happened to be a man of action and, not of words, the farmers, traders and industrialists had deep trust in him. His political  and military strategy  along with his innate ability and sagacity  to implement them were in full display during the integration of Hyderabad province comprising 80,000 sq. miles  when the Nizam was was misled by certain anti-Indian Union activists. Patel launched what was called ''Operation polo'' to convince Nizam to join the Indian Union and not to fall prey to Pakistan's false promises and diabolism. In this case, a bit of coercion and military action was inevitable.  As for the princely state of Travancore, the then Dewan Dr. Sir. C.P. Ramaswami Aiyar and the ruler initially hesitated to join the Indian Union and later  came around and joined the Indian Union.  Thus Patel placed a major role in the integration of this states and a couple of states in Gujarat.

Post-Independence period was a turbulant one and on purpose the British left India in the lurch. But for Patel's  timely political  action and foresight, the Dominion of India would not have become a reality and it was indeed a distinguished accomplishment in modern Indian history without causing any complex political  or social problems leading to unrest, revolt and bloodshed. With respect to Kashmir Nehru and his cronies bungled it when they got the first distress call from the then Hindu Maharajah. The action came late from Nehru's side and Pakistan already intruded Kashmir and  held part of Kashmir illegally. As of now the Kashmir problem still persists with no solution insight. If patel were in Nehru's position, Kashmir won't not have become a contentious issue. His two letters to Nehru pointed out threats from China in the frontier states and India's internal security. 

Patel  had political differences with Nehru and was at loggerheads with him on many political matters, but his ego and self-esteem never stood between them, as protecting the larger interest of the Congress party was more important to him than other issues. Being a man of large heart,  to save the image of the party, he withdrew his candidacy for Congress President's post in favor of Nehru in 1946, thus proving his loyalty to Gandhiji. He never lived for himself nor did he live for his personal esteem or economic gain. He lived for his mother land, its Democratic process and growth. 
Lord Mountbatten, the last Gov. Gen. of India remarked about Patel, ''By far the most important achievement of the present government is the unification of the states into the Dominion of India. Had you failed in this, the results would have been disastrous  ...'' 

A strong and united India owes a debt of gratitude to this man of nerve and steel whose patriotic zeal and persuasive skill made the Princely states join the Indian Union. 

This project won appreciation as well as criticism, especially from the media and other party leaders. It is  alleged that people's hard-earned money is being wasted on projects like Statue of Unity though several villages of the area and other places  are still devpoid of basic facilities like schools, hospitals and drinking water.
