This Saturday, South Knox’s Marble Springs, the homeplace of one of Tennessee’s most dynamic but complicated founders, John Sevier, will celebrate its annual Sevier Day, just before Gov. Sevier’s 279th birthday. (Did you know he was half Spanish?) At 3:00 that day, our Jack Neely will be talking not just about Sevier’s own life, but also about the complicated heritage of his home within the context of the history of South Knoxville and 20th-century tourism. In the last 200 years, this once-remote complex of cabins has been utterly forgotten, mostly destroyed, subject to surprising proposals (like moving the cabins to downtown Knoxville) but eventually exalted as a statewide shrine. Free event.
