Terminology and etymology
The name Rathdown is a Anglicisation of the Irish “Ráth en Duin,” which means “ring forts of the fort.” Dun Laoghaire, means “Laoghaire’s fast.”
In Ireland, the word “county” has traditionally come before rather than after the county’s name: thus ” County Clare” in Ireland as opposed to “ClareCounty ” in Michigan, USA. But the counties created after 1994 often drop the word “County” completely or use it by name, such as Internet search engines show many more uses of Irish seats in the “Dún Laoghaire-Rathdown” than either “Rathdown County Dun Laoghaire-” or “Dun Laoghaire-Rathdown County “. There seems to be no official guidance on the issue and the local authorities use all three forms. 
There is no “Rathdown” city in the county. The modern county is basically the same divisions as medieval half-barony of Rathdown, a division of County Dublin.
Although it is the smallest county in Ireland in terms of area, it is also the county with the longest name. In addition, the official legal name of the county, in English, is spelled without a síneadh fada on the “u” in the Irish-speaking part of the name “Dun Laoghaire”  (although the current style in the county is to use síneadh fada on the name in both Irish and English).  thereason for this [ citation needed ] is that the names of the new Dublin county councils never examined at committee level in the Houses of the Oireachtas, and was last changed in 1991 local Government Act, which took effect. Both parliamentary debates and Dublin County Council’s own reorganization report published in 1992 concluded that the name Dún Laoghaire-Rathdown was “unacceptable”. A one-year proviso in the 1993 Local Government (Dublin) Act to change the name of the county at the local level were allowed by the new Council. The legislation allows the elected members of the Council to comment on further legislation to change the name of the county.
The motto on the insignia of the County Council’s reading, Ó Chuan go Sliabh , Irish for “From the port to the mountain.” The crown of the device is that King Lóegaire mac Neill (Laoghaire, the högkung in the fifth century, who lived in the area).
