The house, now a museum maintained by Bethany College (founded by Campbell in 1840), was designated a National Historic Landmark in 1994.

[2][3] The Campbell Mansion is located a short way east of Bethany, on property that is partially crossed by West Virginia 67.

It originally had a porch on the west side, which was enclosed by Alexander Campbell in 1819, adding a second story to provide dormitory space for his seminary.

[3] Alexander Campbell was a native of Ireland who came to the United States in 1809, where he joined his father Thomas as a religious minister in western Pennsylvania.

Campbell founded Bethany College in 1840, and served as its president until his death; its graduates seeded many new schools and churches across the country.
