The Gateway Arch rises 630 feet above the west bank of the Mississippi River in St. Louis, Missouri — the tallest man-made monument in the United States and one of the most graceful structures in the world. Officially part of what was long called Jefferson National Expansion Memorial (now renamed Gateway Arch National Park), the stainless steel catenary arch was designed by architect Eero Saarinen and completed in 1965 as a monument to Thomas Jefferson’s vision of western expansion and the role St. Louis played as the gateway to that expansion. From the ground, the arch looks almost impossibly slender and precise; from the top, where small windows frame the Mississippi Valley in every direction, you understand why people travel from around the country just to stand in its uppermost chamber.
Riding the Tram to the Top
The tram system inside the Gateway Arch is one of the more unusual visitor experiences in the national park system. Rather than a conventional elevator, each leg of the arch contains a series of interconnected capsule-shaped tram cars that travel along a curved track following the arch’s interior curve from ground level to the observation chamber at the apex. Each tram car holds five passengers and takes about four minutes to reach the top. The observation chamber at 630 feet contains 16 small windows on the east and west sides, each offering views across the Mississippi toward Illinois on one side and into downtown St. Louis on the other. The chamber is narrow — roughly 65 feet long and just over 7 feet wide at its widest — so it can feel crowded when busy. Tram tickets require advance reservation; book through recreation.gov before your visit, especially for summer or holiday weekends.
The Museum of Westward Expansion
Directly beneath the arch, accessed through the underground visitor center on the park grounds, the Museum of Westward Expansion traces the history of American expansion from the Louisiana Purchase through the settling of the West. The museum was redesigned and significantly expanded in a major renovation completed in 2018, creating a modern, thematic experience built around original artifacts including a Conestoga wagon, Native American cultural objects, explorer equipment, and extensive documentary materials on Lewis and Clark’s Corps of Discovery. Interactive elements and oral history components give the museum a contemporary feel while the artifact collections retain their historical weight. Plan at least an hour; the full museum at a deliberate pace takes 90 minutes or more. Museum admission is included with tram tickets but can also be purchased separately if you prefer not to ride to the top.
The Old Courthouse: Justice and History
The Old Courthouse, located two blocks west of the arch, is part of the national park and worth a significant portion of your visit. This was the site where Dred Scott — an enslaved man who had been taken to free states and territories — sued for his freedom in 1846 in the case that eventually reached the Supreme Court and whose 1857 decision denied citizenship rights to African Americans, helping to accelerate the nation’s path toward Civil War. The courthouse’s interior dome is an extraordinary piece of nineteenth-century civic architecture, and the exhibits inside trace the Dred Scott case and broader themes of justice, freedom, and American law with care and historical depth. Admission to the Old Courthouse is free; it’s open during regular park hours.
The Grounds and the Mississippi Riverfront
The park grounds between the arch and the river are a broad, landscaped corridor that has been redesigned in recent years to improve connections to the Mississippi riverfront. Walking the riverside path at sunset, with the arch towering behind you and barge traffic moving on the river ahead, is one of St. Louis’s best urban experiences. The riverfront has excursion boat companies operating from the levee below the arch, offering one-hour sightseeing cruises on the Mississippi that provide a completely different perspective on both the arch and the river. Paddle-wheeler architecture, a nod to the nineteenth-century riverboats that made St. Louis a commercial hub, characterizes most of the tour boats.
Practical Visitor Information
Gateway Arch National Park is located in the heart of downtown St. Louis, easily accessible by car (with multiple nearby parking garages), light rail, and taxi or rideshare from anywhere in the metro area. The underground visitor center has restrooms, a café, and the museum gift shop. The park is open year-round with the tram operating daily except Thanksgiving, Christmas, and New Year’s Day. Summer visits are busiest; weekday mornings in spring and fall offer the shortest tram waits.
