Lauderdale County was formed, from lands that were once part of the Chickasaw Nation, in February 1818, when Alabama was still a territory. A visit to the county seat, Florence, provides an opportunity see the largest Indian mound in the Tennessee Valley, experience a historic stagecoach tavern, learn about blues musician W.C. Handy, and tour the only dwelling in Alabama designed by Frank Lloyd Wright. Joe Wheeler State Park, which is on the Tennessee River near Rogersville, offers hiking, fishing, and other recreational activities. Wilson Dam, also on the Tennessee River, is designated as a National Historic Landmark.
