The Gateway Arch is the most iconic symbol of St. Louis and a lasting tribute to America’s westward expansion. Rising 630 feet over the city, this stainless-steel monument stands as the tallest arch in the world and draws millions of visitors each year.

Located on the banks of the Mississippi River, the Gateway Arch forms the centerpiece of the Gateway Arch National Park—formerly known as the Jefferson National Expansion Memorial. In this guide, we will help you discover the rich history, architecture, and experiences the Arch has to offer.

The History Behind the Gateway Arch

The idea for the Gateway Arch originated in the 1930s as part of a broader vision to revitalize St. Louis’s riverfront and commemorate its role in the nation’s westward expansion. It honors President Thomas Jefferson, who oversaw the Louisiana Purchase, and pioneers like Meriwether Lewis and William Clark, who began their famed expedition from this very region.

Construction began in 1963 and was completed in 1965, designed by renowned Finnish-American architect Eero Saarinen, whose vision helped the structure become a global icon. In 1987, the Arch was designated a National Historic Landmark, further solidifying its importance in American history.

Architectural Marvel: Design and Construction

The Gateway Arch is a weighted catenary curve, an engineering feat rarely seen in modern monuments. Standing 630 feet tall and 630 feet wide at its base, it is both elegant and structurally resilient—able to withstand earthquakes, high winds, and time itself.

Made of stainless steel and reinforced concrete, the Arch was assembled using a triangular segment design, hoisted into place with precision. At its peak is a viewing area that can be accessed by a unique tram ride system—offering breathtaking views of downtown St. Louis and the Mississippi River.

This design reflects Saarinen’s commitment to modernism and minimalism, and today, the Arch is considered one of the greatest achievements in 20th-century architecture.

Gateway Arch National Park: What to See and Do

The Gateway Arch is part of a 91-acre national park managed by the National Park Service (NPS). The site includes multiple attractions that educate and entertain.

1. The Tram to the Top

Visitors can ride a one-of-a-kind tram to the top of the Arch, where an observation deck offers panoramic views stretching up to 30 miles on clear days. It’s an unmissable experience for photographers, architecture fans, and families alike.

2. The Museum at the Gateway Arch

Fully renovated in 2018, the Museum at the Gateway Arch provides a state-of-the-art look at 200 years of American history. Exhibits explore the expansion of the West, the role of Native Americans, and St. Louis’s development as the Gateway to the West.

3. Riverboat Cruises

The Gateway Arch Riverboats offer scenic cruises along the Mississippi River. These narrated tours provide historical context and a unique angle of the Arch and St. Louis skyline.

4. Old Courthouse

Another historic highlight, the Old St. Louis Courthouse, is where the first two trials of the Dred Scott case were held—one of the most significant legal battles in American civil rights history. The courthouse is part of the Arch’s national park grounds and is also administered by the NPS.
