Princeton Battlefield State Park Overview

The famous Mercer Oak once stood in the middle of the battlefield not far from the spot where General Hugh Mercer fell during the Battle of Princeton.

In one of the fiercest battles of the American Revolution, American troops under General George Washington surprised and defeated a force of British Regulars on the morning of January 3, 1777. American soldiers, pushed back by a strong British assault, were rallied by Washington who rode his horse between the British and American lines, leading his men to his first field victory over British troops. The Battle of Princeton capped 10 days of maneuvering and fighting, including three battles, which began with Washington’s famous December 25, 1776 crossing of the Delaware.

Thomas Clarke, a Quaker farmer, acquired 200 acres in 1772 from his older brother William. He subsequently built a house and lived there with his sisters Sarah and Hannah as well as Susannah, a black woman enslaved by the Clarke Family. The Clarke farm includes the original two-story half-Georgian frame house and enlarged wing, the carriage barn and smokehouse. The house, consisting of seven rooms, is furnished in the period of the Revolution. Much of the original flooring, moldings and windows remain.

Clarke House Hours: Wednesdays through Saturdays from 10 a.m. to noon and 1 p.m. to 4 p.m. and Sundays from 1 p.m. to 4 p.m.

On January 3, 1777, the peaceful winter fields of Thomas and William Clarke’s farms were transformed into the site of what is considered to be one of the fiercest fights of its size during the American Revolution. During this desperate battle, American troops under General George Washington surprised and defeated a force of British Regulars. Coming at the end of "The Ten Crucial Days" which saw the well-known night crossing of the Delaware River and the two battles in Trenton, the Battle of Princeton gave Washington his first victory against the British Regulars on the field. The battle extended over a mile away to the College of New Jersey (now Princeton University).

The historic Mercer Oak, believed to have been present during the Battle of Princeton, once stood on the battlefield near what is now Mercer Road. It collapsed from old age in March 2000. An offspring grown from an acorn of the Mercer Oak in 1981 now thrives next to the large stump of the original tree.

Education Programs
Visitors may partake in various educational programs held throughout the year.

History/Nature Tours
Visitors may tour a number of the historical monuments located within the park, including: Princeton Battlefield, the Clarke House Museum, the Mercer Oak, the Ionic Colonnade and the medallion, a stone patio marking the approximate gravesite of 21 British and 15 American soldiers killed in the battle.

Colonnade and Gravesite
The Ionic Colonnade was originally the facade of a Philadelphia home, later called St. George’s Hall, designed by Thomas U. Walter in 1836. It was re-erected in the park in 1959 as the entrance to the common grave of 21 British and 16 American soldiers killed in the Battle of Princeton. A poem written for the grave by Alfred Joyes in 1916, then a visiting Princeton professor and later Poet Laureate of England, is inlayed in bronze over the grave.

The Princeton Battle Monument
The monument is located on state park property at the corner of Stockton Road and Nassau Street in Princeton borough. Built on the site of British defensive works it was designed by renowned sculptor Frederick MacMonnies and dedicated in 1922 by President Warren G. Harding.

The Stony Brook Friends Meetinghouse
Adjacent to the park, is the still active Friends Meetinghouse. Originally built in 1726, it was rebuilt in 1760 following a fire. Used as a barracks during part of the British occupation of Princeton in 1776, it also sheltered the wounded after the battle. The graveyard contains many unmarked graves of local Quakers as well as soldiers killed in the battle and the grave of Richard Stockton, signer of the Declaration of Independence.

Cross-Country Skiing
The park’s open lawns and numerous trails along the Institute Woods are suitable for cross-country skiing in the wintertime.

Hiking
A paved and gravel path travels the perimeter of the park. Adjacent to the park, the Institute Woods is comprised of a 589-acre mixed hardwood, wetlands and agricultural land with a variety of trails that are suitable for hiking. There are no specific ADA trails but most are level to slightly graded. Hiking trails lead to the Delaware and Raritan Canal.

The park’s open fields as well as adjacent wetlands are ideal for observing birds in their natural habitat.
