Eero Saarinen's soaring stainless steel Gateway Arch on St. Louis's riverfront memorializes the city's role in westward expansion. Visitors can ascend the 630-foot arch and see extensive exhibits on American Indians, Thomas Jefferson, Lewis and Clark, and others in the underground Museum of Westward Expansion. In the nearby Old Courthouse a slave named Dred Scott sued for his freedom in 1846.
