Fort Donelson National Battlefield, Tennessee
Fort Donelson in Dover, Tennessee, falls on the edge of the path of totality during the Aug. 21 solar eclipse, during which viewers will experience approximately 45 seconds of darkness. Viewing opportunities will be available from the main lands of the park and from the Dover Hotel (Surrender House), overlooking the Cumberland River. Totality will start at 1:25 p.m. local time.
The Confederacy established Fort Donelson during the American Civil War. The Dover Hotel was built between 1851 and 1853, accommodated riverboat travelers before and after the war, and served as Gen. Simon Buckner's headquarters, according to the NPS website.
The park will also host special solar eclipse programs throughout the summer, including a presentation by NASA solar system ambassador Theo Wellington on June 13 and a Junior Ranger activity on June 17 for children ages 5 to 9.
