Retuertas horse (also known as Caballo de las Retuertas or
Caballo de las Retuertas de Donana) are a rare horse indigenous to the
Andalusia region of Spain. They are believed to closely resemble the ancient
Iberian horses that populated Spain before being domesticated. They are now now
found only in the Donana National Park in the provinces of Huelva and Sevilla,
and in The Biological Reserve "Campanarios de Azaba" in Espeja
(Salamanca province) a part of which is the research reserve of the Consejo
Superior de Investigaciones CientÃficas, the Spanish National Research Council.
According to a genetic study by the CSIC, the Retuertas horse is one of the
oldest European breeds.
