Museum at the Gateway Arch
A free underground museum examining St. Louis, Indigenous nations, empire, river commerce, migration, and the contested idea of western expansion.
Artwork inspired by Eero Saarinen
The museum beneath the Arch uses maps, objects, media, and large-scale environments to cover colonial St. Louis, Tribal homelands, the fur trade, U.S. expansion, slavery, river commerce, migration, and the making of the monument.
It gives essential context before a tram ride because the Arch’s elegant symbolism can otherwise flatten conflict into inevitability. Admission to the museum is free, while the small tram capsules, documentary films, river cruises, and other experiences have separate tickets and constraints.

Good to know
