Probably built in the first decade of the 1800s, it rises two and a half stories under a gabled tin roof with interior end chimneys, and has a five-bay west facade with a center entry and porches on both levels. A one-story concrete block addition sits on the north side. The building served as an inn and layover for stagecoaches on the Brookville, Indiana-Cincinnati route. Livestock pens once held farmers' animals headed to market, and the owners ran a nearby toll gate and a post office. In 1847 it became the home of John Bennett, a politician and lobbyist. Morgan's Raiders struck it in July 1863, and local tradition says Abraham Lincoln stayed there. The form describes the two-story brick design as unusual for the rural area.","period_of_significance":"c. 1800-1810","architect_builder":null,"architectural_style":"Federal","criteria":[],"status_note":"Described as in fair condition; the data sheet entry lists it as currently vacant, and the nomination form marks it as unoccupied.
