This James River plantation was the birthplace of William Henry Harrison, ninth U.S. President and Benjamin Harrison V, a signer of the Declaration of Independence. It also lays claim to hosting America's first Thanksgiving in December of 1619, long before the Pilgrims arrived. It played a major role in the Civil War, as the headquarters and supply base for McClellan's Union Army. The plantation features five terraced gardens leading from the house to the James River that
were dug by hand before the Revolutionary War, and the mansion built in 1726, which is still family-owned.
