Morristown National Historical Park consists of four non-contiguous areas: Washington’s Headquarters Museum, Fort Nonsense, Jockey Hollow, and the New Jersey Brigade Area (which includes the Cross Estate and Gardens). 

For two critical winters of the American Revolution, 1777 and 1779-80, General George Washington chose the Morristown, New Jersey area as the Continental Army’s main winter encampment. Because of its strategic location, the area continually served as the military capital throughout the war. During the 1779-1780 Jockey Hollow encampment, over 10,000 soldiers endured the war's most severe winter.

Established in 1933, Morristown National Historical Park preserves, protects, and maintains the landscapes, structures, features, archeological resources, and collections of the Continental Army winter encampments, the headquarters of General George Washington, and related Revolutionary War sites at Morristown for the benefit and inspiration of the public. The park interprets the history and subsequent commemoration of these encampments and the extraordinary fortitude of the officers and enlisted men under Washington’s leadership.
