The Rock House is an eighteenth-century stone dwelling and the only surviving house associated with the Colonial Wrightsboro Settlement, founded in 1768. Built by Thomas Ansley, it used weathered granite quarried in its natural form from the nearby geographical fall line, along with pine timbers and cypress shingles, giving the house a distinctive Georgia character. Its architectural style resembles stone houses in the Delaware Valley of New Jersey, from which Ansley migrated, and it is the earliest dwelling in Georgia with its original architectural form intact. Ownership passed to Nicolas C. Bacon in the eighteen forties and in the eighteen fifties to the Johnson family, who maintained it as a working plantation until the twentieth century. The Johnson heirs, Effie Johnson Usry and Mary Ruth Johnson McNeil, gave the house to the Wrightsboro Quaker Community Foundation, Inc. in 1966, and it was restored in 1981.
