and is a registered historic landmark in both Virginia and Chesterfield County. Ampthill (Chesterfield County, Virginia) Ampthill Plantation was located on the south bank of the James River about four miles south of the head of navigation at modern-day Richmond, Virginia. Built by Henry Cary, Jr. about 1730, it was just upstream of Falling Creek. It was later owned by Colonel Archibald Cary, who maintained a flour mill complex and iron forge at the nearby town of Warwick. Mary Randolph was born there in 1762. In 1929 the manor house at Ampthill was dismantled and moved to a site on Cary Street Road in the West end of Richmond where it still stands today. The former plantation property is now occupied by a DuPont plant.
