The townland is the smallest territorial division of civil administration. Dating from medieval times or earlier, it was used to identify a small area of land on a local level.

These small divisions of land were later used as the basis for plantation grants in the sixteenth and seventeenth centuries and were considerably altered following subdivisions.

The townland was used, not only for regular land transactions such as the imposition of rents, but also as the primary division in major land valuations, surveys and census such as the Tithe Applotment books, and Griffith’s Valuation.

It has lost some of its administrative functions although it is still of use for statistical purposes. Its significance now lies primarily in enabling the identification of small localised rural areas. Parts of an individual townland may lie in different civil parishes, and may be, but not necessarily so, in different in Roman Catholic parishes. The same townland names can be found in different parishes and counties.
