Surrounded by the main business district of Morristown is a parklike area about 2½ acres in size. Here was the old Morristown Green of eighteenth century times. On the green itself, then crossed by roadways, stood the Morris County Courthouse and Jail, where both civil and military prisoners were confined during the Revolutionary War. About a dozen other buildings faced toward the green, among them the Arnold Tavern (No. 5), the Presbyterian and Baptist Churches (p. 9), and, in the winter of 1779-80, a large structure where Continental Army supplies were stored. Extending from the southwest side of the green was a broad, open space about 150 feet in depth and 250 feet long. This was often used for drill and parade purposes by both Continental troops and militia.

SITE OF ARNOLD TAVERN, WASHINGTON’S HEADQUARTERS, 1777. Facing the northwest side of Morristown Green, about 100 to 150 feet from the present Washington Street corner, is the site of the Arnold Tavern, which, according to local tradition, served as Washington’s headquarters in the winter of 1777 (p. 5). Built some years before the Revolutionary War, this structure was originally quite pretentious and handsomely furnished. During the nineteenth century it was converted into stores, and, in 1886, removed to another part of Morristown. Fire completed destruction of the building some 25 years later.

Continuing from the south end of Court Street is a road leading upward into the Fort Nonsense Area of the park. There, at the top of a steep hill (the northern terminus of Mount Kemble), visitors may see a restored earthwork originally built at Washington’s order in 1777. How the name “Fort Nonsense” came into being is unknown. It does not appear in any available written record before 1833, nor has anyone yet authenticated the oft-repeated story that the Commander in Chief’s reason for constructing this work was merely to keep the American troops occupied and out of mischief. Washington’s real intention is disclosed by an order of May 28, 1777, issued as the Continental Army moved to Middlebrook (p. 11). In this he directed Lt. Col. Jeremiah Olney to remain behind at Morristown, and with his detachment “and the Militia now here ... Guard the Stores of different kinds ... Strengthen the Works already begun upon the Hill near this place, and erect such others as are necessary for the better defending of it, that it may become a safe retreat in case of Necessity.” Other orders confirm the conclusion that Fort Nonsense was actually built to serve a very practical purpose.
