The Statue of Liberty was first publicly displayed in 1876 at Philadelphia’s Centennial Exposition, when the right arm and torch were exhibited. In 1878, the head was displayed at the Paris World Fair. France presented the statue, called "Liberty Enlightening the World," to the United States in 1886. The United States supplied the pedestal. The statue is a representation of Libertas, the Roman goddess of freedom.
Sculptor Frederic Auguste Bartholdi, designer of the statue, made the woman's face in the likeness of his mother, Charlotte. The framework for the statue was developed by Gustave Eiffel, who later created the Eiffel Tower.
While the interior structure of the statue is iron, the outer surface is copper which, over time, has turned green from oxidation. Three hundred different kinds of hammer were used to work the copper. In 1984, the original torch was replaced by a copper one coated in 24k gold leaf.
The entire Statue of Liberty, from its base to the tip of the torch, is 305 feet 1 inch tall. It has a waistline measurement of 35 feet, a nose 4 feet 6 inches long and an index finger 8 feet in length. The statue wears sandals equivalent to a U.S. women's size 879.
To reach the crown, visitors must climb 354 steps. The circlet has 25 windows and seven spikes. These points symbolize the world's seven continents and oceans, which emphasizes liberty across the globe.
