“The Gateway to the West” is commemorated at the Gateway Arch National Park in St. Louis, Missouri. This stainless steel structure stands 630 feet tall and is the tallest man-made monument in the Western Hemisphere. The museum below displays the story of Native Americans, pioneers, and explorers that paved the way for America during the westward expansion dating back to 1764. The Gateway Arch sits riverfront along the Mississippi River and offers riverboat cruises.
