The Horse Trust (formerly The Home of Rest for Horses until September 2006) is an equine charity in the United Kingdom, based at Speen near Princes Risborough in Buckinghamshire. It was founded in 1886 to help the working horses in London, making it the oldest horse charity in the world. Upon the decline of the working horse in the 1960s it widened its remit to include education and research, becoming the largest provider of equine welfare grants in the United Kingdom.
The Horse Trust's Home of Rest for Horses operates at its Westcroft Stables in the Chiltern Hills between High Wycombe and Aylesbury, in Buckinghamshire. As of 2010 it provides lifetime sanctuary for more than 100 horses, donkeys and ponies.
The Horse Trust has four main programmes of activities - providing lifetime sanctuary for retired horses, ponies and donkeys, promoting horse welfare, funding research into horse health and welfare, and educating people about horse health and ownership.
The Horse Trust provides lifetime sanctuary for around 100 retired horses, ponies and donkeys at its Home of Rest for Horses in Speen, Buckinghamshire.
Residents at the sanctuary come from varied backgrounds including the mounted police force, the mounted Army regiments, the Royal Mews and Riding for the Disabled.
Over the years, the Home of Rest has housed a number of famous horses, including Sefton (horse), a horse injured by the IRA's Hyde Park bombing on 20 July 1982 and Monarch, who led the team of horses that pulled the Queen's coach during the 2002 Golden Jubilee celebrations.
The Horse Trust funds research into equine welfare and works with the RSPCA to help rehome abandoned or neglected horses, ponies and donkeys. In January 2008, it took in a number of severely neglected horses from Spindles Farm, which The Independent described as "one of the worst cases of animal cruelty in recent history".
The Horse Trust funds non-invasive research into equine diseases, such as strangles, sweet itch, colic, grass sickness and cardiology. It also funds clinical training scholarships in various areas including surgery and anaesthesia.
