Reference, evidence, and public education for the historic counties.

Historic counties are the enduring geography. Councils are administration, lieutenancies are ceremonial – neither define the counties.

County Geography

Sligo meets Donegal to the north-east, Leitrim to the east and south-east, Roscommon to the south, and Mayo to the west and south-west, while the Atlantic forms the county’s northern and western sea edge. The county is shaped by Sligo Bay, the Garavogue and Lough Gill, the mountain blocks of the north, and the lower inland country to the south.

Sligo is easy to recognise through Sligo Bay, the mountain wall, and the southern plain.

Names

  • Sligo
  • County Sligo
  • County of Sligo
  • Contae Sligeach

Sligeach is the Irish form of Sligo. County Sligo is the formal historical style, the county name means the shelly place, and the older county background includes the prehistoric and mythic landscape around Knocknarea, Carrowmore, and the north-west coast.

Sligo was a county by the sixteenth century, and the county’s own combination of bay, river, coast, and mountain has kept its shape distinct ever since. That bay-and-mountain geography still gives the historic county a clear shape.
