A legacy equestrian estate and storied stud farm in Lexington, Kentucky, that has nurtured champions across three breeds for almost 300 years is being sold by the family of Ryanair co-founder and billionaire, Tony Ryan.
As much of a trophy estate as it is a billionaire-owned trophy cabinet, the centuries-old, 950-acre estate, known as Castleton, has bragging rights to several championship-winning horses and is celebrated in the racing world for breeding and raising some of the most famous horses in the sport, including standing top sire Domino.

According to listing agent Bluegrass Sotheby’s, Castleton is one of the most photographed estates in the US, having been used in several equestrian-themed films. It is available for the first time in 25 years.

Modern functionality, historic sporting legacy
Castleton’s equestrian facilities, residences and landscape has evolved over centuries rather than decades.
As functional as it is historic, the estate operates as a self-sufficient compound with ten residential homes across the property ranging in size and architectural complexity, including staff quarters and managers’ accommodation.
At the heart of Castleton stands a landmark, 7-bedroom Greek Revival mansion spanning 13,500 square feet.

The property also includes several distinctive architectural features, including a round stone tower, tree-lined drive, covered bridge and a rare equine cemetery serving as a visual archive of provenance and purpose.
A much-loved nursery for best-in-class horses, equestrian infrastructure is at the heart of the estate, offering new stewards exceptional, hard-to-replicate facilities on which to build on and expand as a multi-generational horse-breeding business.
At the time of sale, the horse farm offers an unmatched scale of infrastructure that spans 16 barns ranging from 4-stall setups to a substantial 30-stall facility, totaling 268 stalls





An estate revealing layers of American history
Castleton reveals successive layers of American history rather than representing a single architectural period. Its pedigree is long and illustrious.
Established in 1739 when Kentucky functioned primarily as a rich hunting ground, the stud farm and estate has passed through the hands of powerful senators, Wall Street financiers, entrepreneurs, banking dynasties and industrial-era heirs.
In the early 1890s, Wall Street tycoon James R. Keene acquired the farm and purchased additional land to bring the operation to almost 1,000 acres. Keene usually referred to the farm as “Castleton Stud”, and under his direction, it became one of the greatest Thoroughbred operations of its day
In 1945, the estate expanded its equestrian operations to include Standardbred and American Saddlebred horses. Frances Dodge Johnson, the daughter of automotive pioneer John Dodge, operated the facility during this period.

Over the years, the farm grew into a large-scale equestrian property while retaining its historic buildings and landscape.

Castleton goes under the hammer
In 2001, the estate passed into the hands of Ireland’s seventh-richest man, who would bring it into its sharpest iteration.
Ryanair co-founder and billionaire Tony Ryan purchased the estate for $14 million in 2001, becoming the sixth steward to carry on the horse-breeding legacy. Ryan renamed it Castleton Lyons after his Irish estate Lyons Demesne.
He carried out extensive restoration that included renovating barns, planting more than 2,000 trees and restoring the mansion. After Ryan died in 2007, his son Shane Ryan continued to run it as a Thoroughbred breeding operation and is now looking to sell due to personal and travel commitments.
Commenting on the sale, Shane Ryan said that he welcomes the next in line with the keys to “to wrap their arms around this place and truly enjoy it.”

The 951-acre equestrian property will go under the hammer in October as the final lot at the invitation-only Keeneland Championship Sale – an auction held annually during the week of the Breeders’ Cup in Lexington.
The estate will be sold at auction in conjunction with Bluegrass Sotheby’s International Realty.
Shannon Arvin, Keeneland’s president and CEO, said: “Every year we ask ourselves how we can push the Championship Sale forward, giving our guests an unforgettable event and buyers something they can’t find anywhere else.
“We’re excited to work alongside Sotheby’s on this once-in-a-generation offering and honoured to be part of the next chapter for the farm and the Ryan family’s legacy.”

Castleton is America’s ultimate, one-of-one legacy equestrian assets with unmatched pedigree and exceptional gravitas in horseracing and breeding circles.
