Constructed for the 1964 New York World's Fair, the Unisphere is a 120 foot stainless steel globe, the world's largest, designed by the landscape architect Gilmore D. Clarke to fit into his larger plan for the park. The globe is circled by three orbital rings representing the orbits of Yuri Gagarin, John Glenn, & the Telstar satellite. This globe replaced the older Perisphere which was constructed in the same location for the 1939 World's Fair but scrapped at the end of the event.
