From the 1965 Official Guide Book to the New York World's Fair, describing the New York State Pavilion:
"Above a huge "Tent of Tomorrow," housing state exhibits and shows, rise three towers, one of them an observation tower 226 feet high.
Various displays are sheltered under the world's largest suspension roof, made of translucent colored plastic and hung from sixteen 100-foot concrete columns. On the main floor the Texaco Oil Company has inlaid a mammoth map of the state in terrazzo, and here visitors assemble to watch school and community groups perform. Near-by is a movie theater-in-the-round."
The structure was kept after the fair closed, but no uses were ever found for it. Now it lies in repose, too expensive to rehabilitate, too expensive to tear down.
