The Statue of Liberty, officially named the Statue of Liberty Enlightening the World, is situated on Liberty Island, at the entrance to New York Harbor. The Statue of Liberty, inaugurated in 1886, was a gift from the French to the United States to mark the centennial of the American Declaration of Independence. It was made by the French sculptor Bartholdi, in collaboration with French engineer Gustave Eiffel. They designed the massive structure using thin pounded copper sheets covering a steel framework. The statue measures 93 metres from the ground to the top of the torch. The robed female figure represents Libertas, the Roman goddess of freedom. As one of the most well-known landmarks in the world, the Statue of Liberty is synonymous with freedom and liberty.
