The Gateway Arch is a 630-foot-tall (192 m) monument in St. Louis, Missouri, United States. Clad in stainless steel and built in the form of a weighted catenary arch,[5] it is the world's tallest arch[4] and Missouri's tallest accessible structure. Some sources consider it the tallest human-made monument in the Western Hemisphere.[6] Built as a monument to the westward expansion of the United States[5] and officially dedicated to "the American people", the Arch, commonly referred to as "The Gateway to the West", is a National Historic Landmark in Gateway Arch National Park and has become a popular tourist destination,[4] as well as an internationally recognized symbol of St. Louis.

The Arch was designed by the Finnish-American architect Eero Saarinen in 1947, and construction began on February 12, 1963 and was completed on October 28, 1965,[7][8] at an overall cost of $13 million[9] (equivalent to $95.9 million in 2023).[2] The monument opened to the public on June 10, 1967.[10] It is located at the 1764 site of the founding of St. Louis on the west bank of the Mississippi River.[11][12][13]
