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

Longford meets Leitrim to the north-west, Cavan to the north-east, Westmeath to the east and south, and Roscommon across the Shannon to the west. The county is shaped by the long western river line, the low bog and lake interior, and the slight rise toward the Cavan side in the north-east.

Longford is easy to recognise through the Shannon edge, central bogland, and slight north-eastern rise.

Names

  • Longford
  • County Longford
  • County of Longford
  • An Longfort

An Longfort is the Irish form of Longford. County Longford is the formal historical style, the county name points to a fortified place, and the older background reaches into Tethbae and Annaly in the north midlands.

Longford became a county in the late sixteenth century, but its Shannon-side and bogland geography had already marked it off as a recognisable district. That north-midland landscape still gives the historic county a clear shape.
