This magnificent Georgian mansion, its various outbuildings and dependencies, and the historic ground which surrounds it represent a small preserve in which the entire scope of Virginia heritage can be understood and appreciated. Today Chatham is part of Fredericksburg & Spotsylvania National Military Park. The buildings and grounds are open daily 9:00-4:30. Five of the ten rooms contain exhibits and the rest of the building as well as the outbuildings are park offices.
