Chatham Manor is one of the most historic homes in America. Chatham was built between 1768 and 1771 by William Fitzhugh and is located on the Rappahannock River in Stafford County Virginia. The home lies directly across the river from city of Fredericksburg, Virginia. During the Battle of Fredericksburg, Chatham served as Union headquarters for General Burnside. After the battle, Chatham served as a hospital and assisting with the wounded were Clara Barton and poet Walt Whitman.
