Newington Archaeological Site preserves the remains of a historic plantation at King and Queen Courthouse, Virginia, best known as the birthplace and childhood home of Carter Braxton, a signer of the Declaration of Independence. Although the plantation house and a later reconstruction were both lost to fire by the first decade of the 20th century, the site still contains the mansion location, outbuilding foundations, cellars, and an 18th-century stone building. Its landscape retains a cemetery, historic road, and falling-garden terraces. Archaeological evidence also reaches far earlier, with Native American deposits from the Woodland period dating from about 1200 BC to AD 1600.
