The first official meeting of An Taisce, The National Trust for Ireland, takes place on July 15, 1948, at the Royal Irish Academy‘s headquarters, Academy House on Dawson Street, Dublin.

An Taisce is established on a provisional basis in September 1946 and incorporated as a company based on an “association not for profit” in June 1948. It is a charitable non-governmental organisation (NGO) active in the areas of the environment and built heritage in the Republic of Ireland. It considers itself the oldest environmental and non-governmental organisation in the country and is somewhat similar to the National Trust of England, Wales and Northern Ireland but based more directly on the National Trust for Scotland. Its first president is the prominent naturalist Robert Lloyd Praeger.

An Taisce is a membership-based charity, rather than a state or semi-state organisation, or quango, but it does receive government and European Union funding for specific programmes, such as Blue Flag beaches, and Green Schools private-sector funding for, for example, the Irish Business Against Litter surveys, and a mix of State and private funding for the annual National Spring Clean. An Taisce has for decades also had a statutory role in certain planning and environmental processes in the country.

The work of the organisation includes policy recommendation and campaigning in the built and natural heritage areas, the holding in trust of relevant properties, and environmentally relevant education. It has a number of local associations, which may assist in caring for properties, and monitor planning in their areas.

A public meeting to consider the need for a national trust is held in the Mansion House in September 1946, convened by the Royal Irish Academy, the Royal Society of Antiquaries of Ireland, An Óige, the Geographical Society of Ireland, the Dublin Naturalists’ Field Club and the Irish Society for the Preservation of Birds. The meeting resolves to create such a body, and elect both a provisional committee, and a council of 16 plus 4 co-opted members, who secure bankers, auditors and solicitors. After extensive debate, the two-part name is chosen and application is made to form a not-for-profit company. Special approval is sought from the Minister for Trade and Commerce for charity-appropriate memorandum and articles, adhering to the “association not for profit” section of the then Companies Act, with a prohibition on distribution of surpluses, and for permission to omit the word “Limited” from the company name.

An Taisce is an indirect successor to the all-Island National Trust Committee which had ceased to exist in 1946 after the passing of the Northern Ireland National Trust Act.

The organisation is duly incorporated as a company limited by guarantee on June 28, 1948. The initial constitution is modelled on that of the National Trust for Scotland. The first official meeting of the company was held on July 15, 1948, at the Royal Irish Academy’s headquarters, Academy House on Dawson Street, and the first annual general meeting is convened on September 23 of the same year, with formal greetings from the National Trust and the National Trust for Scotland.

Notable founder directors and council members include Robert Lloyd Praeger, James Sleator, Michael Parsons, 6th Earl of Rosse, Patrick G. Kennedy, Arthur Cox, George Francis Mitchell and, co-opted, Cearbhall Ó Dálaigh, Seán MacBride and Colm Ó Lochlainn. Praeger was elected as the first president of the organisation and Professor Felix Hackett as chairperson. Praeger makes an opening address which is subsequently broadcast nationally by Raidió Éireann.

An Taisce’s headquarters are in Dublin’s oldest surviving guildhall, the Tailors’ Hall, which it helped to restore.
