Why it's listed

Rising about 35 feet above the Deep River near Cumnock, this stone blast furnace was built between 1862 and 1864 by the Endor Iron Company to produce pig iron for the Confederacy. It is roughly 32 feet square at the base and is laid without mortar from rough-cut reddish-gray local stone. Each side has a round-arched opening with a keystone, and the corners, arches and keystones have dressed, beveled edges. Inside, part of a double-ring fire brick flue survives. The furnace belonged to what appears to have been the largest iron mining and processing venture ever tried in North Carolina. After the war, new owners converted it to a hot blast and added a rolling mill and foundry by 1872. Smaller-than-expected ore deposits and unfinished river navigation works hindered the business, and the furnace had stopped operating by 1874. It is now the only intact structure from the enterprise and a reminder of the region's mid-nineteenth-century industrial boom.

Significance in brief: It is the only intact structure left from what was evidently the largest iron mining and processing operation ever attempted in North Carolina. It was built to supply iron to the Confederacy and is among the best-preserved nineteenth-century smelting furnaces in the state. Its monumental size and fine stonework are also noted.
