Dublin City Council, to the
west by the county of
South Dublin and to the south by County Wicklow.
University College Dublin

that comprise the "
Dublin Region": the three smaller counties into
County Dublin was divided in 1994, which along with the city of
Dublin. Located to the south-east of the capital city of Dublin, the
county town of
Dún Laoghaire–Rathdown is Dún Laoghaire. It was
created in 1994 by merging the areas under the jurisdiction of the
Dún Laoghaire and the south-eastern part of the former
Dublin County Council. Additionally, the powers of the former
Deansgrange Joint Burial Board were subsumed into the new authority.
Since 2015, the county lies within the Eastern & Midland Regional
Authority, one of three such subdivisions of the state.

Terminology and etymology
The name Rathdown is an anglicisation of the Irish "Ráth an Dúin",
meaning "ring-fort of the fort" and
Dún Laoghaire means "Laoghaire's
In Ireland the word "County" has traditionally come before rather than
after the county's name: thus "County Clare" in Ireland as opposed to
"Clare County" in Michigan, US. However, the counties created after
1994 often drop the word "County" entirely or use it after the name:
for example, internet search engines show many more uses on Irish
sites of "Dún Laoghaire–Rathdown" than of either "County Dún
Laoghaire–Rathdown" or "
Dún Laoghaire–Rathdown County". There
appears to be no official guidance on the matter and the local
authority uses all three forms.
There is no "Rathdown" town in the county. The modern county follows
virtually the same divisions as the medieval half-barony of Rathdown,
a subdivision of County Dublin.
While it is the smallest county in Ireland in terms of area, it is
also the county with the longest name. Furthermore, the official legal
name of the county, in English, is spelt without a síneadh fada on
the "u" in the Irish-language part of the name, "Dún Laoghaire"
(although the current style within the county council is to use the
síneadh fada on the name in both Irish and English). The reason
for this is that the titles of the new
councils were never examined at committee stage in the Houses of the
Oireachtas, and were last altered under the 1991 Local Government Act
which was rushed into effect. Both parliamentary debates and Dublin
County Council’s own reorganisation report published in 1992
concluded that the name Dun Laoghaire-Rathdown was "unacceptable". A
one-year proviso contained in the 1993 Local Government (Dublin) Act
for changing the name of the county at local level was allowed to
expire by the new council. The legislation permits the elected members
of the council to make representations for additional legislation
altering the name of the county.
The motto on the insignia of the County Council reads, Ó Chuan go
Sliabh, Irish for "From Harbour to Mountain". The crown in the device
is that of King
Lóegaire mac Néill
Lóegaire mac Néill (Laoghaire, the High King of
Ireland in the fifth century, who resided in the area).

Dún Laoghaire–Rathdown County Council
Dún Laoghaire–Rathdown County Council is the local authority for
the county. There are six Local Electoral Areas (LEAs) for the county
which return a total of 40 councillors as follows: Killiney-Shankill
(6), Blackrock (6), Dundrum (7),
Dún Laoghaire (8),
In 1986, the "administrative county" of
Dublin was divided into three
"electoral counties": Dún Laoghaire-Rathdown,
Dublin — Fingal, and
Dublin — Belgard. In 1994,
Dublin County Council and the
Dún Laoghaire were abolished and the three electoral
counties became "administrative counties", named Dun
Laoghaire-Rathdown, Fingal, and
South Dublin respectively. In 2001,
the "administrative counties" were redesignated as simply "counties".
The three counties together with
Dublin city constitute the Dublin
Region. The label "County Dublin" continues to be used informally for
this area (the city has been administered separately from County
Dublin since 1548).
For elections to Dáil Éireann, the county is split between the
Dún Laoghaire (4 representatives) and Dublin
Rathdown (3 representatives), with the division generally running
along the N11. These constituencies currently have four
Fine Gael TDs,
one Green Party TD, one Solidarity–People Before Profit TD and one
Dublin region forms the
Dublin constituency in European Parliament

Dublin Area Rapid Transit system runs through the eastern coast of
the county and connects to
Dublin city centre to the north as well as
other points north and south on the
Iarnród Éireann railway system,
with connections to Intercity trains. The green
Luas line runs through
the centre of the county.
There is a medium-sized harbour at Dún Laoghaire, with now
discontinued ferry crossings to and from
Holyhead in North Wales; this
was a popular route for tourists travelling across the
Irish Sea from
Britain. This service was suspended indefinitely in September 2014.
