Gateway Arch and Old Courthouse, St. Louis, Missouri

The Gateway Arch, a stainless steel catenary curve, stands behind the Old St. Louis County Courthouse in St. Louis, Missouri. Completed in 1965, the Gateway Arch was designed by Eero Saarinen to commemorate the westward expansion of the United States. The Old Courthouse, completed in 1862, is a National Historic Landmark that served as the site of the Dred Scott case and Virginia Minor's lawsuit for suffrage. Today, both structures are part of the Gateway Arch National Park.
