Originally a grain mill, the Darden Mill was an important part of the industrial railyard. Built in 1902 by the Elkins Milling company, the steam-powered roller miller was converted to electric in 1910. Products such as flour, cereals, and animal feed were shipped by rail. Ralph Darden operated the mill as the Darden Company (DARCO), selling feed and supplies from 1919 to 1943. After a fire in 1937 destroyed the upper floor, the building was repaired to the shape it has today. The original timber-framed posts and beams remain visible in the mill. In 2003, Citizens for Historical Opportunity, Preservation, and Education in Randolph County (C-HOPE) rescued the building from demolition and rehabilitated it. The restored historic building now plays a part in the transition of the railyard from industrial to tourism and community use.
