A partnership of the National Monument Services of the Department of Housing, Local Government and Heritage and the Office of Public Works, looks after the national monuments in State care. The conservation and presentation of these monuments is project-managed by the OPW with responsibility for the archaeological aspects of projects resting with the Department. The consent of the Minister for Culture, Heritage and the Gaeltacht is required for any works at or in proximity to national monuments in State care.
The country is divided into six works districts, each with a team of specialist craftsmen and general operatives reporting to a district works manager, under the general direction of a senior conservation architect.
