Ocracoke Light
Various claims have been made about the light, including "the Ocracoke Light is the second oldest operating lighthouse in the nation," from the National Park Service. The original 1795 construction a mile away would qualify only as fifth oldest and the current 1823 tower is about twelfth oldest.
