Coolbeg, County Fermanagh


Ir. Cúil Bheag “little corner, angle or peninsula”


Coolbeg lies on the eastern shore of Upper Lough Erne, about three miles west of Lisnaskea.

The derivation of the name of the townland is clearly An Chúil Bheag “the little corner or angle” as suggested by Donnell Maguire.  Coolbeg is now joined to the neighbouring townland of Inishcreenry by a narrow isthmus.  However, Inishcreenry was formerly an island and Coolbeg previously formed a peninsula.  In coastal locations the element cúil “corner, angle” can sometimes refer to a point of land or peninsula, and in the case of Coolbeg this may be its significance.  According to Joyce, the barony of Coole which borders the parish of Aghalurcher on the south is named from a peninsula extending into Upper Lough Erne, the original Irish name of which is Cúil na nOirear “the angle (i.e. peninsula) of the coasts or harbours” (Joyce i 531).
