Gateway Arch – St. Louis, Missouri
The Gateway Arch gracefully rises 630 feet (192 m) above the west bank of the Mississippi River. It salutes the westward expansion of the United States and is the focal point of the Jefferson National Expansion Memorial. The Arch was designed by Finnish-American architect Eero Saarinen in 1967. It began welcoming visitors to the observation area in 1967. Designed as an inverted weighted catenary curve, it directs the forces of thrust directly through its legs into its foundation. Built from 142 prefabricated stainless steel sections, its double-walled skins were filled with concrete after installation.
