The Iveagh Trust /ˈaɪviː/ is a provider of affordable housing in and around Dublin, Ireland. It was initially a component of the Guinness Trust, founded in 1890 by Edward Guinness, 1st Earl of Iveagh, great-grandson of the founder of the Guinness Brewery, to help homeless people in Dublin and London. It is not otherwise related to the brewery company.
The Guinness Trust extended its objectives outside London in 1962 and today operates in all parts of England as a member of the Guinness Partnership, a group of housing associations. However, the Iveagh Trust became a separate organisation in 1903 with responsibility for activities in Ireland. It was given a statutory legal basis by the "Dublin Improvement (Bull Alley Area) Act" of 1903. Today it is run as a charity under Irish law and liaises with such bodies as Dublin City Council and the Homeless Agency.
In today's central Dublin several original buildings in the area of St. Patrick's Cathedral, Patrick Street and Christ Church Cathedral are still managed. Following a report by Dr. John Lumsden, they were built between 1896 and 1945 by the Iveagh Trust, including formerly the Iveagh Public Baths and the Iveagh Market building on Francis Street. Lord Iveagh also made donations to St Patrick's Cathedral and created the St Patrick's Park gardens in 1901 between the cathedral and the Iveagh Trust buildings. Today's buildings were therefore only a part of a larger urban renewal plan, at a time when Dublin was infamous for its poverty and its unsanitary tenements.
