TWA Flight Center -- New York, New York (1962)

Dubbed the “Grand Central of the Jet Age” by critic Robert A.M. Stern, Saarinen’s curvaceous terminal was a paean to the romance of flight. The sloped concrete roof recalls two flapping wings, while contours constantly bend and flow into each, creating a fluid collection of terminals, staircases and forms. “We wanted passengers passing through the building to experience a fully-designed environment, in which each part arises from another and everything belongs to the same formal world," said Saarinen. After being shuttered for years, the space is set to be turned into a luxury hotel. Photo courtesy Wikipedia.  Photo 7 of 10 in Design Icon: Architect Eero Saarinen
