The Unisphere is a spherical stainless steel representation of the Earth in Flushing Meadow-Corona Park, in the City of New York borough of Queens. It measures 140 feet high and 120 feet in diameter.
The globe was designed by Gilmore D. Clarke as part of his plan for the 1964 New York World's Fair.
During the 1964 fair dramatic lighting at night gave the effect of sunrise moving over the surface of the globe. Also, the capitals of nations were marked by lights. One of these lights is placed at the location of the Kahnawake Indian Reservation, which the Mohawk ironworkers requested to be placed there in honor of their labor.
In 1966, after the conclusion of the fair, US Steel donated $100,000 to make the globe permanent at Flushing Meadows-Corona Park.
