The Museum of Westward Expansion

The Museum of Westward Expansion, a part of the Jefferson National Expansion Memorial National Park, is located below the Gateway Arch. And by "below" we mean "underground"! The museum is the size of a football field and it is all under the Arch grounds. It features artifacts from the Lewis and Clark Expedition, letters and documents about the Louisiana Purchase, exhibits on the native Americans that lived in the Mississippi River Valley, as well as photos and a documentary movie on how the Arch was built. Special exhibits and events change seasonally.
