Gateway Arch National Park

Gateway Arch National Park, 90.9 acres (36.8 hectares), St. Louis, Mo., est. 1935 as Jefferson National Expansion Memorial, designated a national park and renamed 2018. Located on the Mississippi, the park commemorates the Louisiana Purchase and St. Louis's role as the gateway to the West. The Gateway Arch, from which the park takes its name, is a stainless steel arch, 630 ft (192 m) high and the same distance from leg to leg at its base, with an observation deck inside at the top. It was designed by Eero Saarinen and erected in 1963–65. Other sites included in the park are the Old Courthouse (1839–64), where the Dred Scott Case was tried, and the Museum of Westward Expansion.
