Gateway Arch

The Gateway Arch is a striking 630-foot-tall stainless steel monument in St. Louis, Missouri, symbolizing the city's role as the "Gateway to the West." Designed by architect Eero Saarinen and completed in 1965, it reflects America's westward expansion and exploration. Its sleek, curved shape forms a hyperbolic paraboloid, and visitors can ascend to an observation deck inside for panoramic views of the Mississippi River and surrounding area. As an engineering marvel, the Arch combines aesthetic appeal with structural innovation, making it a renowned cultural and architectural landmark.
