It is also home to the Museum of Westward Expansion, which honors pioneers Meriwether Lewis and William Clark and houses rare artifacts from their time.The Old Courthouse, another famous St. Louis landmark, is famous for its role in the Dred Scott trial -- a landmark Supreme Court case. The decision also deemed unconstitutional the Missouri Compromise, the first attempted congressional solution to the slavery debate.
