Build in 1866 for Ernst Schowengerdt and his wife Elesebet (Hukreden), this residence was continuously owned and occupied by them or their descendants until the death of Margaret Carol Schowengerdt, along with the associated real estate, was transferred to the Warren County Historical Society through the Margaret Schowengerdt Trust. The house was designated as a National Historic Place by the U. S. Department of Interior in 1980.
