Kentucky Horse Park will be home to the first 'Festivale' of Endangered Equines.
The September 5-7 festival will draw more than 125 horses and ponies of 15 different breeds.
It is being hosted by the conservation organisation Equus Survival Trust and sponsored in part by KEEP (Kentucky Equine Educational Project).
The event will focus on raising awareness within the general public and encourage networking among breeders and associations.
The exhibition theme, "Celebrate the Differences" is designed to encourage visitors to explore and cherish the differences in these endangered historical breeds.
Admission to the event is included with admission to the Kentucky Horse Park.
Activities include an endangered breed pavilion, demonstations, booths, youth activities, a drill team performance, lectures, a silent auction, and clinics with Lendon Gray (dressage) and Muffy Seaton (driving).
