History Dún Laoghaire–Rathdown County Council came into being on 1 January 1994. Dún Laoghaire–Rathdown County Council is a successor to local government structures that have existed in the area since 1834. The Council was established under the Local Government (Dublin) Act 1993 by the merger of the Corporation of Dún Laoghaire and that part of Dublin County Council that chiefly corresponded to the former Rathdown No 1 Rural District. The two sides of the county have distinct histories in terms of local government structures. On the Dún Laoghaire side of the county, the Borough of Dún Laoghaire had been established by the Local Government (Dublin) Act 1930 as a successor body to urban districts of Dún Laoghaire, Blackrock, Dalkey, and Killiney and Ballybrack. Those Commissioners for Kingstown were established in 1834 and were subsequently renamed Kingstown Urban District Council and then Dún Laoghaire Urban District Council. On the Rathdown side of the County, Dublin County Council and Rathdown No. 1 Rural District Council were established under the Local Government (Ireland) Act 1898. Rathdown No. 1 Rural District Council was abolished by the Local Government (Dublin) Act 1930. On its formation, the Town Hall in Dún Laoghaire became the headquarters of Dún Laoghaire–Rathdown County Council. It was subsequently renamed County Hall.
