Burwell-Morgan Mill, also known as the Millwood Mill, is a historic grist mill located at Millwood, Clarke County, Virginia. It was built about 1785 by Gen. Daniel Morgan and Lt. Col. Nathaniel Burwell, who both served in the American Revolution. Burwell was the project's financier and Morgan managed the construction. The project overseer was L.H. Mongrul, whose initials and the date 1782 are carved in a stone in the mill's wall. The mill operated until the 1950s. In 1964 it was donated to the Clarke County Historical Association, which finished restoration in 1970 and operates the mill as a museum.
