Highlights of the park include the Princeton Battlefield site; the Clarke House Museum (see below); Mercer Oak, a tree which stood in the middle of the battlefield; the Ionic Colonnade designed by Thomas U. Walter (architect of the US Capitol Building); and a stone patio marking the grave of 21 British and 15 American soldiers killed in the battle. A poem was written for the site by Alfred Noyes, Poet Laureate of England.
