Heritage conservation has been in place in Ireland since the formation as the state, with structures protected under local, national and international legislation.
National legislation In the 1930s, a national policy was adopted in the form of the
National Monuments Act, which established preservation orders, listed national monuments, and outlined standards, prohibitions, and regulations of archaeological objects. The National Monuments Service, an agency of the
Office of Public Works, is responsible for National Monuments. As of 2020, the National Monuments Service had responsibility for the conservation of approximately 1,000 individual structures at over 760 different sites.
Local legislation The Planning and Development Act 2000 establishes that each regional planning authority (administered by
county and city councils in Ireland) is responsible for maintaining a
Record of Protected Structures. These structures may be protected for conservation from an architectural, historical, archaeological, cultural, social or technical perspective. Owners or occupiers of a listed protected structure are obliged to prevent the structure from becoming endangered through damage or through neglect. As of 2020, the various Records of Protected Structures contained over 40,000 structures nationally.
International conventions Ireland has been a member of
UNESCO, the United Nations Educational, Scientific and Cultural Organization, since 1961. As of 2020, there are two
UNESCO World Heritage Sites in the Republic of Ireland. These structures are in the
Brú na Bóinne complex in County Meath and on
Skellig Michael in County Kerry.
Non-government agencies A number of non-government and voluntary organisations (including
An Taisce (the National Trust for Ireland), the
Dublin Civic Trust, the
Irish Landmark Trust, and the
Mining Heritage Trust of Ireland) undertake architectural conservation projects on a non-statutory basis. == Environmental conservation ==
