History and boundaries

Dún Laoghaire (2020–present)

The constituency was created in 1977, succeeding the earlier Dún Laoghaire and Rathdown constituency which had been created in 1948. The constituency is in the eastern coastal area of Dún Laoghaire–Rathdown county (part of County Dublin till 1994), including the town of Dún Laoghaire and the villages of Ballybrack, Blackrock, Booterstown, Cabinteely (east of the N11 road), Dalkey, Deansgrange, Glasthule, Killiney, Loughlinstown, Monkstown, Sallynoggin, Shankill, and Stillorgan.
