Gateway Arch -- St. Louis, Missouri (1965)

"Relevant, beautiful, perhaps inspired would be the right word" was how one judge described Saarinen’s winning submission in 1948 to build the centerpiece of the Jefferson National Expansion Memorial, the St. Louis Arch. Standing as the nation’s tallest man-made monument, the 630-foot-high curve of concrete and stainless steel stands as a focal point of the St. Louis riverfront and poignant symbol of national confidence and innovation. Both Eero and his father submitted designs, and a mix-up meant the family temporarily thought the elder Eliel had won. Photo courtesy Wikipedia.  Photo 4 of 10 in Design Icon: Architect Eero Saarinen
