Gateway Arch National Park preserves the iconic 630 foot stainless steel arch symbolizing westward expansion. Located in St. Louis, it commemorates the citys role as a gateway to the American frontier. Visitors ride a unique tram system to the top for sweeping views of the Mississippi River and downtown. The park also includes the Old Courthouse, where pivotal Dred Scott trials took place.
Its blend of architecture, history, and riverfront scenery makes it one of the most urban national parks. The Arch remains a powerful symbol of exploration and national identity.
