On June 28, 1863, a brigade of Confederate soldiers advanced on York. In an attempt to undo Confederate troop movement eastward across the Susquehanna River, the townspeople of York, who were loyal to the Union, did the only thing they could. They torched the Wrightsville Bridge, a covered bridge that provided them important social and economic links to Lancaster County and points east. The Burning of the Bridge Diorama, housed in a building that stands a stone's throw from the river, tells the story of the night the bridge was set ablaze. Destruction of the bridge was a strategic act that prevented Confederates from crossing the river. In so doing, the South's attention turned toward the town of Gettysburg and, thus, altered the Civil War's outcome.
