Museum complex consists of four buildings: the Andrew Johnston House, the Doctor's Office, the Research Library and the Museum. The "country home estate" of Andrew Johnston (circa 1829) typifies Federal-style architecture of the nineteenth century. It is furnished with many pieces of original furniture, including some that predate the Civil War. Dr. Harvey Green Johnston I built the Doctor's Office in 1857. It was used by area physicians for nearly a century. During the Civil War, the office served as temporary headquarters for two future presidents--Rutherford B. Hayes and William McKinley. Research Library has records on local history and genealogy. County history exhibits found in the Museum, include Native American artifacts, Revolutionary and Civil War relics and the bank and post office from the town of Eggleston, Va.
