One of Kentucky’s most historic horse farms, with connections to the late co-founder of Ryanair, is heading to auction this fall with a listing price of $57.5 million.
The 951-acre property, better known as Castleton Farm, dates back to 1793 when future U.S. senator John Breckinridge purchased land outside Lexington. He handed the property down to his daughter, whose husband David Castleman built the 1840s Greek Revival mansion that still stands on the property today. At the time, the estate also adopted the name honoring Castleman’s family.

Under the ownership of Wall Street financier James Keene, the property turned into a horse farm in the 1890s. It quickly rose to prominence as a Thoroughbred nursery, producing racing champions like Domino, Sysonby and Ben Brush. The property later expanded to include both Standardbred and American Saddlebred horses in 1945 while automotive pioneer John Dodge’s daughter Frances Dodge Johnson operated the facility.

Irish businessman and Ryanair co-founder Tony Ryan purchased the property in 2001 for $14 million, according to the Wall Street Journal. His family carried out extensive renovations to the estate, including new barn roofs and other improvements.

When Tony died in 2007, the ownership of Castleton Farm transferred to his son, Shane Ryan. He has since operated the property as a horse-breeding farm. However, he is now looking to sell the property because he is spending more time in Europe and his kids are not as interested in horses, listing agent Ken Donworth of Bluegrass Sotheby’s International Realty told the Journal.
