The Casper and Abraham Shafer Gristmill complex is the most intact surviving nineteenth century gristmill complex in Sussex County. The property includes the existing mill and a full hydro system, which features a nearly quarter-mile-long headrace. The system was built in 1844 on the ruins of an earlier gristmill that was destroyed by fire. Casper Shafer, among the first European settlers of Stillwater and a member of the New Jersey Provincial Congress, constructed the gristmill in 1764. This replaced a still earlier mill that Shafer had built in the early 1740s about 1,500 feet or less to the northeast from the current mill building.
