County Donegal shares border with Northern Ireland
Geography and subdivisions
Located in the northwest corner of Ireland, Donegal is the island's northernmost county. In terms of size and area, it is the largest county in Ulster and the fourth-largest county in all of Ireland. Uniquely, County Donegal shares a small border with only one other county in the Republic of Ireland – County Leitrim. The vast majority of its land border (93%) is shared with three counties of Northern Ireland: County Tyrone, County Londonderry and County Fermanagh. This geographic isolation from the rest of the Republic has led to Donegal people maintaining a distinct cultural identity and has been used to market the county with the slogan "Up here it's different". While Lifford is the county town, Letterkenny is by far the largest town in the county with a population of just under 20,000. Letterkenny and the nearby city of Derry form the main economic axis in the northwest of Ireland. Indeed, what became the City of Derry was officially part of County Donegal up until 1610.
It is part of the Northern and Western Region (a NUTS 2 European statistical Region), within which it is part of the Border strategic planning area.
