Both the house and the historic siegeearthworks were restored in 1976. The Moore House is located in the eastern part of the park and is where surrender negotiations took place in 1781. Nearby, the state-operated American Revolution Museum at Yorktown and the Yorktown Riverwalk Landing area are located.
