Historic county of Ireland
Leitrim

Liatroim / County of Leitrim
Province: Connacht
Shannon and lough country south, rugged hills north — with a narrow Atlantic shore.
Leitrim changes markedly from south to north. The southern county belongs to the upper Shannon and the lake country of the north Midlands, a relatively low landscape of water, pasture and wetlands.
Further north the terrain becomes increasingly broken, wooded and upland before rising into the mountain country of the north-west. Beyond it, Leitrim reaches the Atlantic through an exceptionally short stretch of coast. Few counties compress river, lake, mountain and ocean into such a narrow territory.

County geography
The Shannon country
The Shannon gives southern Leitrim its strongest geographical line.
Lakes, wetlands and low pasture place this part of the county firmly within the watery landscapes of the north Midlands.
North Leitrim
The northern landscape is dramatically different.
Valleys become narrower, hills higher and the relationship with the neighbouring mountain country of north-west Ireland much stronger.
A small Atlantic opening
Leitrim is sometimes mistakenly imagined as landlocked.
Its Atlantic shore is very short, but geographically significant: the county reaches all the way from the Shannon system to the ocean.
