A townland is a small geographical division of land, historically and currently used in Ireland and in the Western Isles in Scotland, typically covering 100–500 acres (40–202 ha). The townland system is of Gaelic origin, antedating the Norman invasion, and most have names of Irish origin. However, some townland names and boundaries come from Norman manors, plantation divisions, or later creations of the Ordnance Survey. The total number of inhabited townlands in Ireland was 60,679 in 1911. The total number recognised by the Irish Place Names database as of 2014 was 61,098, including uninhabited townlands, mainly small islands.
