The N.Y. State Pavilion: This spectacular building was designed by Philip Johnson. The guidebook description:

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 plastic and hung from sixteen 100-foot columns.

The translucent panels were removed as a safety hazard.
