Coolmore Ireland
Coolmore was originally a relatively small farm dedicated to general agriculture, but came into the Vigors family in 1945 when a training operation was established there. It was inherited by
Tim Vigors, famous fighter pilot in the
Battle of Britain
The Battle of Britain, also known as the Air Battle for England (german: die Luftschlacht um England), was a military campaign of the Second World War, in which the Royal Air Force (RAF) and the Fleet Air Arm (FAA) of the Royal Navy defended ...
and in the Far East. Having left the air force, he firstly joined Goffs bloodstock auctioneers before setting up his own bloodstock agency in 1951. He moved to Coolmore in 1968 and began transforming it into the well known stud farm it is today.
Vigors went into partnership with his friend
Vincent O'Brien, a leading racehorse trainer, and
Robert Sangster, the Vernons pools magnate. He later sold his interest to O'Brien and his son-in-law,
John Magnier. Eventually, Magnier became sole owner, and built the farm into a multi-national, multibillion-euro operation.
The farm currently occupies over 7000 acres.

In the mid-1970s, Coolmore became very active in the American sales market, displaying particular interest in the offspring of
Northern Dancer
