A 951-acre Kentucky horse farm with roots stretching back to 1793 is headed for the auction block this fall, listed at $57.5 million. Castleton Farm, long associated with Ryanair co-founder Dr. Tony Ryan, will be sold as the final lot of Keeneland's third annual Championship Sale on October 28, just days before the 2026 Breeders' Cup World Championships.
The listing, first reported by WDRB, confirms the farm spans 951 acres and will change hands through an unusual pairing of Keeneland's auction platform and traditional luxury real estate marketing. Bluegrass Sotheby's International Realty has listed the property at $57.5 million, and according to TrueNicks, the arrangement marks an unprecedented collaboration between Keeneland and a real estate agency for selling equine real estate. The property includes a 13,500-square-foot 1840 Greek Revival mansion, ten additional residential homes, 16 horse barns with a combined 268 stalls, a covered bridge, ornate iron entrance gates imported from London, and a historic equine cemetery, per the same report.
From Cabell's Dale to a Racing Dynasty
The land's story predates the farm's current name by decades. Virginia native John Breckinridge, who later served as a U.S. Senator and U.S. Attorney General, purchased 2,467 acres in 1793 and named the tract Cabell's Dale after his wife's family, according to the Paulick Report. The property was renamed Castleton in the 1840s by owner David Castleman, the outlet notes.
Decades later, the farm became a cornerstone of American Thoroughbred breeding. From 1893 to 1911, Wall Street financier James R. Keene ran Castleton as one of the nation's premier Thoroughbred nurseries, breeding or standing 1896 Kentucky Derby winner Ben Brush, undefeated champion Colin, Commando, and Peter Pan, according to BloodHorse. Keene's operations produced 113 stakes winners during his tenure, the outlet reports.
The farm's story didn't stay confined to Thoroughbreds. In 1945, Dodge automotive heiress Frances Dodge Johnson acquired Castleton and converted it into a world-renowned harness racing and show horse operation, with World Champion Five-Gaited stallion Wing Commander transferred to Castleton alongside multiple Hambletonian and Little Brown Jug winners, per the same account. The property went on to operate primarily as a Standardbred nursery for more than 50 years under the Van Lennep family, according to Racing Post.
The Ryan Family Era
Irish aviation entrepreneur and Ryanair co-founder Dr. Tony Ryan purchased Castleton Farm around 2000, renaming it Castleton Lyons after his Irish estate Lyons Demesne and funding extensive renovations to return the land to Thoroughbred breeding, BloodHorse reported at the time. Current president Shane Ryan took over operations following his father's death in 2007, the outlet notes.
Under the Ryan family's stewardship, Castleton Lyons bred or stood top Thoroughbreds including three-time Eclipse Award winner Gio Ponti, prominent stallion Malibu Moon, Grade 1 winner Jack Christopher, and 2017 Kentucky Derby starter Gormley, according to TrueNicks. Homebred stallion Gio Ponti earned more than $6.16 million on the track, per the outlet's reporting.
The farm has also carved out a cultural niche beyond the racetrack. The Dr. Tony Ryan Book Award offers a $10,000 purse and Tipperary crystal trophy for excellence in Thoroughbred racing literature. The award reception is traditionally held in the loft of the farm's historic stallion barn, the outlet notes. The 2005 DreamWorks equestrian drama Dreamer, starring Kurt Russell and Dakota Fanning, was filmed in Lexington.
A Novel Sale Format for Breeders' Cup Week
Castleton's sale will unfold within a sales structure that is itself still new. Founded in 2024, the invitation-only Keeneland Championship Sale is an annual auction held on the Wednesday prior to the Breeders' Cup World Championships, typically offering elite race prospects, stallion shares, and breeding rights, according to The Pressbox. This year's edition, the third in the sale's history, will close with Castleton as its headline lot.
Whether a new owner will keep Castleton Lyons running as a commercial Thoroughbred operation or repurpose portions of its nearly 1,000 acres remains an open question, one that will likely hinge on who steps up when the gavel falls on October 28.
