Johnsonville State Historic Park is named for former President Andrew Johnson and Union Military Governor during the Civil War. This 2000-acre park located in Humphreys County, commemorates the site of the Battle of Johnsonville and the historic town site that existed from 1864-1944 prior to the formation of Kentucky Lake.
