Unisphere

The Unisphere is a spherical stainless steel representation of the Earth at Flushing Meadows–Corona Park in Queens, New York City, New York. The globe was designed by Gilmore D. Clarke for the 1964 New York World's Fair. Commissioned to celebrate the beginning of the space age, the Unisphere was conceived and constructed as the theme symbol of the World's Fair. The theme of the World's Fair was "Peace Through Understanding", and the Unisphere represented the theme of global interdependence, being dedicated to "Man's Achievements on a Shrinking Globe in an Expanding Universe".

Clarke devised plans for the Unisphere while aboard an airplane in 1960. New York City Department of Parks and Recreation commissioner Robert Moses, who had already rejected two plans for iconic structures at the 1964 fair, approved Clarke's proposal in early 1961. After further refinements, the Unisphere was constructed by American Bridge Company, a division of U.S. Steel, from March to August 1963. Over 51 million people visited the Unisphere during the World's Fair, after which it became a permanent attraction of Flushing Meadows–Corona Park. The Unisphere became an unofficial symbol of Queens after the World's Fair. In the 1970s, the Unisphere was not maintained and became visibly dirty; it was restored in the early 1990s. The Unisphere was made a New York City designated landmark in 1995 and, after another period of disrepair, it was restored in the early 2010s.
