A short walk south of central Princeton, the battlefield is now a state park of open fields, low stone walls, and the original Quaker meeting house — the structure used as a field hospital after the fighting — still standing on the edge of the site. Two flanking colonnades on the north lawn (the Ionic Mercer Oak Memorial Colonnade) mark the centre of the battlefield. The visitor centre in the Clarke House interprets the engagement well in about thirty minutes.
The site is good for a quiet walk even if you are not a Revolutionary War enthusiast — the topography of the original fields is largely preserved, and the famous Mercer Oak (under which General Hugh Mercer was fatally bayoneted) stood here until it fell in 2000. A sapling grown from the original is now planted near the original site. Free; open daylight hours.
