ST. LOUIS GATEWAY ARCH
Jefferson National Expansion Memorial consists of the Gateway Arch, the Museum of Westward Expansion, and St. Louis' Old Courthouse. During a nationwide competition in 1947-48, architect Eero Saarinen's inspired design for a 630 foot stainless steel arch was chosen as a perfect monument to the spirit of the western pioneers. Construction of the Arch began in 1963 and was completed on October 28, 1965, for a total cost of less than $15 million. The Arch has foundations sunk 60 feet into the ground, and is built to withstand earthquakes and high winds. It sways up to one inch in a 20 mph wind, and is built to sway up to 18 inches. Fees are charged to ride the unique tram system to the top. Acreage: 90.96.

The Museum of Westward Expansion, located below the Arch, is as large as a football field and contains an extensive collection of artifacts, mounted animal specimens, an authentic American Indian tipi, and an overview of the Lewis and Clark expedition.
