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

Counties are geography. Councils run services, lieutenancies are ceremonial – neither defines the counties.

Tyrone

A northern county of clans, battles and bogs.

Tyrone is a largely rural county of central Ulster, defined by rolling farmland, peaceful valleys and the rugged Sperrin Mountains to the north. Sawel Mountain, shared with Derry / Londonderry, is the county's highest point.

County Geography

Tyrone meets Derry / Londonderry to the north, Donegal to the west and north-west, Fermanagh to the south-west, Monaghan to the south, Armagh to the south-east, and Antrim across the Lough Neagh side to the east. The county is shaped by the Sperrins, the long drainage toward the Foyle and Blackwater systems, and the eastern approach to the lough.

Sperrin upland, central valleys, and the eastward fall toward Lough Neagh give Tyrone a strong and readable county form.

Names

  • Tyrone
  • County Tyrone
  • County of Tyrone
  • Chontae Thír Eoghain

Tír Eoghain is the Irish form of Tyrone. County Tyrone is the formal historical style, older records preserve forms such as Tyrowen, and the county name points back to the land of Eoghan and the O’Neill kingdom.

Tyrone was shired in 1585, but the older upland and valley setting of Tír Eoghain still shapes the county. Sperrin, valley, and Lough Neagh-side geography keep the historic county clear.
