The Statue of Liberty was sculpted between 1875 and 1884 under the direction of French sculptor Frédéric-Auguste Bartholdi, who began drafting designs in 1870. Bartholdi and his team hammered roughly 31 tons of copper sheets onto a steel frame. Before being mounted on its current pedestal, the statue stood over 151 feet (46 metres) tall and weighed 225 tons.
