Unisphere

The Unisphere is a spherical stainless steel representation of the Earth in Flushing Meadows–Corona Park in the borough of Queens in New York City, New York, United States. The globe was designed by Gilmore D. Clarke as part of his plan 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".

The Unisphere measures 140 feet high and 120 feet in diameter. It sits atop a 20-foot-tall tripod base with over 500 steel pieces representing the countries, as well as three steel rings representing the first artificial satellites orbiting Earth.
