The Walmart Heritage Museum Lab is a temporary exhibit lasting until Spring of '25. The Classic Walmart Museum on the Square is under renovations, so they've moved down the street about 2.5 blocks and are located in the Ledger building across the main entrance. You can enter from Main Street. Discover the history of Sam Walton, Walmart, and view various oddities from over the years. This is something of a test lab where they are working on improvements for the upcoming renovated museum on the Square.
