London Purchase Farm

The London Purchase Farm, also known as the John Chapman House, is a two-and-one-half story stone house on Eagle Road in Upper Makefield Township, Bucks County, Pennsylvania. Its name recalls a tract of 5,000 acres bought by the London Land Company of Pennsylvania in 1699. The oldest part of the manor house dates to about 1735, the barn has a date stone of 1783 and the carriage house one of 1794, and the property is now about 70 acres with a main house, barn, carriage house, guest house and pond. In late December 1776, before the Battle of Trenton, the house served as headquarters for General Henry Knox and Captain Alexander Hamilton of the Continental Army. It is a contributing property of Washington's Crossing, listed in 1966, and was listed individually on the National Register of Historic Places in 1974 for its significance in military history. The house is most closely tied to the physician and later Federalist congressman John Chapman.
