Arch Museums
Very good museum under the Gateway Arch. Purchasing tickets for the trip to the top of the Arch are found at the National Park site or purchase at the site. You must also visit the museum. The movies are very good, esp the one on the building of the Arch. The Gateway Arch is an amazing structure, sitting right on the Mississippi River in downtown St Louis, MO. Children love the Arch and will talk about it for years after your visit esp if you purchase a minature arch to take home. Adults appreciate the magnificent structure and the photo opportunities from the windows at the top of the Arch.
