The Gateway Arch is perhaps the tallest man made monument in the USA. The arch measures approximately 630 feet long and about 630 feet from end to end horizontally at the base on the ground level. This imposing structure is representative of the Westward Expansion of the USA and is the centerpiece of the Jefferson National Expansion Memorial and has become an internationally famous symbol of St. Louis.
The arch sits at the site of St. Louis' foundation on the west bank of the Mississippi River.


The credit for the design and engineering of this imposing structure goes to the American duo Eero Saarinen and Haanskarl Bandel. The designers adopted the flattened catenary shape to design this monument in clad stainless construction. Construction began in February 1963 and was completed in October 1965 and was opened to the public in June 1967. It is estimated that the Arch is more than 40,000 tonnes in weight.
