Dupont invested a substantial amount of money to make the property a leading breeding and training farm for his Thoroughbred racehorses.
The State of Maryland purchased Fair Hill in 1974, converting the then 5,700-acre (23 km2) property into an equine training complex and a natural resource center.
Barns here at Fair Hill were individually named after some of the du Pont thoroughbred champions such as Parlo, Chevation and Fairy Chant.
The campus also includes 3,000 acres (12 km2) of grasslands and woods which can be used by trainers who wish to take their horses out on trails.
Fair Hill's grade one successes include the Kentucky Derby (Barbaro, Animal Kingdom), the Breeders' Cup Turf (Better Talk Now), Breeders' Cup Distaff (Round Pond), the Arlington Million (Kicken Kris), the Barbaro Stakes at Delaware Park (Xchanger) and (Chelokee), and the Queen Elizabeth II Challenge Cup Stakes (Film Maker).
