Was home to a number of well-known ironmasters from the 1740s to the late 19th century. During the American Revolution,
Robert Erskine managed ironmaking operations from Ringwood, and became
George Washington's first geographer and Surveyor-General, producing maps for the
Continental Army; Washington visited the Manor House several times. Ringwood iron was used in the famous
Hudson River Chain, and for tools and hardware for the army. One of the Manor's last owners was
Abram S. Hewitt, ironmaster, educator, lawyer, U.S. Congressman, and mayor of
New York City. The Manor is part of a
National Historic Landmark District and is open for tours from Wednesday through Sunday year round from 10 am to 3 pm. == Shepherd Lake Recreation Area ==
