Point de repère sphérique futuriste Unisphere

The Unisphere is a spherical stainless steel representation of the Earth, located in Flushing Meadows–Corona Park in the borough of Queens, New York City. The sphere, which measures 140 feet (43 m) high and 120 feet (37 m) in diameter, was commissioned as part of the 1964 New York World's Fair. The Unisphere is one of the borough's most iconic and enduring symbols.

Flushing Meadows–Corona Park, often referred to as Flushing Meadows Park, or simply Flushing Meadows, is a public park in the northern part of Queens, New York City. It is bounded by I-678 (Van Wyck Expressway) on the east, Grand Central Parkway on the west, Flushing Bay on the north, and Union Turnpike on the south.

The Trylon and Perisphere were two monumental modernistic structures designed by architects Wallace Harrison and J. Andre Fouilhoux that were together known as the Theme Center of the 1939 New York World's Fair. The Perisphere was a tremendous sphere, 180 feet in diameter, connected to the 610-foot (190 m) spire-shaped Trylon by what was at the time the world's longest escalator.
