The Trust was formed in 1917 to cater for injured soldiers returning from The Great War.
The British government was responsible for running the care facilities from its inception until 1979, when the Irish state took on those responsibilities. Veterans and their spouses continue to have priority of access to admission to the facilities.
The Board of Trustees, since various compulsory purchase orders of its land for the M50 Motorway and LUAS line has a modest investment fund. This fund is used to support veterans of the British Armed Forces living on the island of Ireland, who are injured or made ill as a result of their military service. The Trustees recently extended this to cover veterans who more broadly may be suffering from ill-health.
In 2017, reflecting the centenary the Trust amended its deeds to provide support to veterans of the Irish Defence Forces.
