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

County Geography

Fermanagh meets Donegal to the north-west, Tyrone to the north and east, Monaghan to the south-east, Cavan to the south, and Leitrim to the south-west. The county is shaped by the Erne system, the outer ring of hills and higher ground, and the enclosed basin that gives Fermanagh its distinctive lakeland form.

Fermanagh is easy to recognise through the Erne lakes and the surrounding ring of higher ground.

Places and routes

Enniskillen, Lisnaskea, Belleek, Irvinestown, and Derrygonnelly show the county from its central lough narrows to its western, eastern, and south-western sides.

Connections

The county’s routes have long funnelled through Enniskillen between the two loughs and then spread along the Erne shores toward Belleek, Lisnaskea, and the southern uplands. Movement follows the same lakeland and shore pattern.

Names

  • Fermanagh
  • County Fermanagh
  • County of Fermanagh
  • Fhear Manach

Fear Manach is the Irish form of Fermanagh. County Fermanagh is the formal historical style, older records preserve forms such as Fermanaghe, and the county name reaches back to the Fir Manach and the Maguire-ruled lakeland lordship.

Fermanagh was made a county in 1585, but the older Erne world and the Maguire association still shape its identity. That lakeland geography keeps Fermanagh clear as a historic county.
