Endor Iron Furnace near Cumnock, North Carolina, was built to exploit iron deposits along the Deep River and operated as a blast furnace from 1861 to 1864, then briefly again from 1870 to 1871. Constructed between 1862 and 1864 of soft local reddish-gray stone, it survives as a substantial example of nineteenth-century ironmaking, about 32 feet square at the base and 35 feet high. During the American Civil War, it produced pig iron for the Confederate Army, linking it directly to the region’s wartime industry. Its later preservation reflects both its unusual survival and its importance in North Carolina’s industrial past.
