This  new display serves as a historical gateway into the formative years of Greene County, Tennessee. It chronicles the transition of the region from a rugged frontier to a cornerstone of the 16th state in the Union.​ At the heart of the exhibit is the pivotal role played by local frontiersmen in the American Revolution. It highlights the Battle of Kings Mountain (1780), where the "Overmountain Men"—many from the Greene County area—marched across the Appalachians to deliver a decisive blow against British loyalist forces. This victory is presented not just as a military feat, but as the catalyst for the region’s distinct identity.
