Dunlap coke ovens

The Dunlap coke ovens are the remnants of a coke production facility near Dunlap, in the U.S. state of Tennessee. Built in the early 1900s, the facility consists of five batteries of 268 beehive ovens, which operated under various companies until the early 1920s. The ovens are now listed on the National Register of Historic Places, and are maintained by the Sequatchie Valley Historical Society as part of Dunlap Coke Ovens Park. The rise of the steel industry during the Industrial Revolution brought about an exponential increase in the demand for coke, a fuel derived from the carbonization of coal that was used primarily in the production of pig iron. The Dunlap coke facility, which converted coal mined atop Fredonia Mountain into coke for use in blast furnaces in nearby Chattanooga, brought drastic change and modernization to Dunlap and the central Sequatchie Valley, the economy of which had long been based on subsistence agriculture. While the ovens themselves are all that remain from Dunlap's coke production operations, the Sequatchie Valley Historical Society has redeveloped the coke ovens area into a substantial public park and museum.
