Gateway Arch

The nation's tallest monument at 630 feet, the Gateway Arch has beckoned visitors since June 1967. The Gateway Arch commemorates Thomas Jefferson and the role St. Louis played in the westward expansion of the United States. A visit to St. Louis isn't complete without standing at the Arch's base and playing professional photographer, but the view from the outside is only half of the experience. Attractions within the Arch include the Journey to the Top (the last tram leaves one hour before closing), educational programs, award-winning documentary movie, and a gift shop.
