Designed by Henry Whitestone for J. B. Wilder, the residence was built in 1874, and Wilder named Bashford Manor after an ancestral home in Maryland. In 1887 George J. Long purchased the farm and turned it into a nationally known racing stable. It was among Kentucky's top thoroughbred horse farms until the horses were sold in 1922. Three Kentucky Derby winners, Azra (1892), Manuel (1899), and Sir Huon (1906), were born here. The peacock blue and yellow silks were carried by two Derby winners, Azra and Sir Huon. Two Kentucky Oaks winners, a Preakness winner, and a Travers winner were also born on this farm. The barns were razed in 1970 and the mansion in 1973, and only the original carriage house remains.
