St. Louis: Gateway Arch (Instantaneo)
The Gateway Arch is a 630-foot (192 m) monument in St. Louis, Missouri.
Clad in stainless steel and built in the form of a flattened catenary arch, it is the tallest man-made monument in the United States, Missouri’s tallest accessible building, and the world’s tallest arch.
Built as a monument to the westward expansion of the United States, it is the centerpiece of the Jefferson National Expansion Memorial and has become an internationally famous symbol of St. Louis.
