Washington’s Headquarters Museum

From www.nps.gov:

During two critical winters of the Revolutionary War, 1777 and 1779–80, the countryside in and around Morristown, New Jersey, sheltered the main encampments of the American Continental Army and served as the headquarters of its commander-in-chief, General George Washington.

General Washington twice chose Morristown due to its strategic location, including proximity to New York City, defensible terrain, important communication routes, access to critical resources, and a supportive community. The park encompasses ground occupied by the army during the vast 1779-80 encampment, and the site of the fortification from the 1777 encampment. The Ford Mansion, where Washington made his headquarters, is an important feature of the park and recalls civilian contributions to the winning of independence.
