The St. Louis Gateway Arch, situated in Missouri, stands out as an exceptional landmark due to its dimensions: reaching a height and width of 630 feet each, rendering it a flawlessly symmetrical edifice. Crafted by Eero Saarinen and finalized in 1965, the Arch was erected to commemorate the nation’s westward expansion. Its form, recognized as a weighted catenary arch, produces a sophisticated and sweeping outline that conveys an impression of ascending while gracefully bending. As the loftiest arch globally and the tallest man-made monument in the Western Hemisphere, this iconic structure holds a distinguished status.
