The Lexington Historical Museum was built out of the former building for the Cumberland Presbyterian Church in Lexington. It features a wide range of preserved historic items and memorabilia, including the sword that Colonel James Mulligan gave up during his surrender during the First Battle of Lexington. It also includes exhibits regarding the 19th-century steamboat trade in Lexington, as well as the river bluff coal mines in the area, the Pony Express and Osage Nation Native American tribe.
