The Gateway Arch reflects St. Louis’ role in the Westward Expansion of the United States during the nineteenth century. The park is a memorial to Thomas Jefferson’s role in opening the West, to the pioneers who helped shape its history, and to Dred Scott who sued for his freedom in the Old Courthouse. Jefferson National Expansion Memorial consists of the Gateway Arch, the Museum of Westward Expansion, and St. Louis’ Old Courthouse. Ranger led tours of the Old Courthouse are led everyday on varying schedules. Please check with the information desk for exact times of tours.
