The Unisphere is a spherical stainless steel representation of the Earth in Flushing Meadows–Corona Park, in the New York City borough of Queens. The sphere, which measures 140 feet (43 m) high and 120 feet (37 m) in diameter, was designed by Gilmore D. Clarke as part of his plan for the 1964 New York World's Fair.
The Unisphere sits atop a 20-foot-tall (6.1 m) base with over 500 steel pieces representing the continents, as well as three steel rings representing the first artificial satellites orbiting Earth. Around the Unisphere is a reflecting pool measuring 310 feet (94 m) in diameter and surrounded by 48 pairs of fountainheads.
Commissioned to celebrate the beginning of the space age, the Unisphere was conceived and constructed as the theme symbol of the 1964–1965 New York 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 was restored after the conclusion of the World's Fair, but fell into disrepair in the 1970s, and was restored in the early 1990s. The Unisphere was made a New York City designated landmark in 1995.
