Its scale, symmetrical facade and pilasters are cited, along with the classical portico added about 1900. Reviewers also noted its association with several locally prominent businessmen and politicians.","narrative":"Whitehall is a large Greek Revival farmhouse on a knoll north of Yellow Springs, Ohio. Construction began in 1842 under Aaron Harlan, who had gained the land through his marriage to the widow of David Chambers Baum. The project was so ambitious that neighbors called it Harlan's Folly. Harlan served in the Ohio Legislature, the Ohio Senate and Congress, was an ardent abolitionist, and hosted political gatherings at the house, including one tied to the founding of the Ohio Republican Party in 1854. Later it became the Allen Stock Farm, and its owners changed the roof to a hipped form and added brackets in 1866. A pedimented Ionic portico was added about 1900. The five-bay facade, brick pilasters, stone foundation and walnut-finished interior reflect its classical design. A later correction limited the nominated area to the house and its immediate surroundings, since the other farm buildings were not considered historically significant.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Greek Revival (Classical)","criteria":[],"status_note":"Condition is marked excellent and altered; the property is occupied as a private residence.
