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]] at [[Flushing Meadows–Corona Park]] in [[Queens]], New York City, United States. The Perisphere was a tremendous sphere, {{convert|180|ft}} in diameter, connected to the {{convert|610|ft|adj=on}} spire-shaped Trylon by what was at the time the world's longest escalator. The Perisphere housed a [[diorama]] by [[Henry Dreyfuss]] called ''Democracity'' which, in keeping with the fair's theme "The World of Tomorrow", depicted a utopian city-of-the-future. The interior display was viewed from above on a moving sidewalk, while a multi-image slide presentation was projected on the dome of the sphere. After exiting the Perisphere, visitors descended to ground level on the third element of the Theme Center, the Helicline, a {{convert|950|ft|m|adj=mid|-long}} spiral ramp that partially encircled the Perisphere.

The name "Perisphere" was coined using the Greek prefix ''peri-'', meaning "all around", "about", or "enclosing". The name "Trylon" was coined from the phrase "triangular pylon".<ref>{{cite web|url=https://whenworldwasfair.wordpress.com/tag/trylon/|title=1939-40 NY World's Fair found in Seattle|website=whenworldwasfair.wordpress.com|date=22 June 2015|access-date=11 January 2022}}</ref>
