The Dummett Sugar Mill in Volusia County, Florida, consists of ruins that are associated with the circa 1825 sugar factory with rum distillery that was part of an operation owned by Thomas Dummett. Using a boiler that Dummett purchased from Barbados, the mill is thought to have been the first steam-operated mill in the region. The ruins today are managed by the Florida Department of Environmental Protection/Florida Park Service, and consist of the foundation, northern wall of the structure, two chimneys, portions of the kettle structure, and water supply features. The mill was constructed from coquina and brick, with the bricks used to line the heating areas of the mill. The north wall contains masonry arches as an architectural support mechanism for stress-relief on the structure.
