Baronies were created after the
Norman invasion as subdivisions of
counties and were used for administration. Baronies continue to be regarded as officially defined units, but they are no longer used for many administrative purposes. While they have been administratively obsolete since 1898, they continue to be used in land registration and specification such as in planning permissions. In many cases, a barony corresponds to an earlier
Gaelic túath which had submitted to the Crown. However, this barony was only created in 1840 out of parts of the Liberties of the City of Dublin. Previously, many of these townlands were part of the
Barony of Dublin City. The distinction between the Barony of Dublin and the Barony of Dublin City is shown by a 1985 order adjusting their boundaries, and the inclusion of the 1842 Act in a 2007 list of unrepealed legislation. Both baronies lie within the former county borough of Dublin, since 2001 redesignated the City of Dublin. == Civil parishes ==
