In the fall of 1791, Washington learned of the newly patented automated milling system invented by Oliver Evans. Evans received U.S. Patent #3 for his groundbreaking system, which moved wheat and flour throughout the mill without the need of manual labor. Washington purchased a license for the patent and had the milling system installed in his gristmill. Today, this milling system is faithfully interpreted, fully-functioning, and open to guests on a seasonal basis.
The first mill was built of logs from the site. Millstones were cut from granite boulders found in the area of what is now Fifth Avenue at Rayen Avenue. This mill operated from 1799 to 1822.In 1823 the original mill was replaced by a second mill.Built by Eli Baldwin, this frame structure served only as a gristmill.
