Like some sort of Island of Misfit Toys, an entirely different New York City could be created purely out of the structures that were designed for the city but never built. Buckminster Fuller’s giant Dome Over Manhattan, I.M. Pei’s Hyperboloid, or Frank Lloyd Wright’s plans for Ellis Island would, individually, have significantly altered the City That Never Sleeps. Together, however, these projects, and hundreds of others that were never realized, would have created a New York City that is drastically different from the one that exists today.
