Washington's Headquarters State Historic Site, also called Hasbrouck House, is located in Newburgh, New York overlooking the Hudson River. George Washington lived there while he was in command of the Continental Army during the final year of the American Revolutionary War; it had the longest tenure as his headquarters of any place he had used.
In 1961 the house was designated a state historic site. It is also the oldest house in the city of Newburgh, and the first property acquired and preserved by any U.S. state for historic reasons.
