Built in stages between 1834 and 1862, the Bunker Hill House, earlier known as the Bunker Hill Tavern, stands as one of Ohio's best representations of Federal-Greek Revival style pike town architecture, a form closely tied to pre-Civil War horse-powered turnpike travel and lodging. It served as a way station for pioneers heading west, for drovers taking animals to Cincinnati stockyards, and as a stagecoach stop on the Eastern Stage Coach Company's Cincinnati Omnibus Line, which operated daily between Cincinnati and Richmond, Indiana. Tavern operations ended in 1858 as turnpike travel declined after the completion of a nearby railroad through Camden, and in 1862 a general store was opened there to supply the area's growing population. That store closed in the early 1900s with the coming of the automobile, which made travel to larger and more distant stores practical. The building was listed on the National Register of Historic Places in 2001 and was designated a Historic Ohio Underground Railroad Site by the Friends of Freedom Society. Among those there who helped runaway slaves reach freedom was Gabriel Smith, known as Old Gabe, a free black man and Underground Railroad conductor who belonged to nearby Hopewell Church, whose network aided escaping slaves. His room at the Bunker Hill House was a small closet under the stairway in the summer kitchen leading to the servants' quarters, and runaway slaves moved secretly along adjacent Four Mile Creek and entered the back of the building for refuge on their journey toward Canada and freedom.
