Boylagh, Historic barony in County Donegal, Ireland
Boylagh is a historic barony in County Donegal that covers a landscape dotted with lakes, islands, and a rocky Atlantic coast. The area rises on granite bedrock that creates an undulating terrain with hundreds of lakes and several inhabited islands, including Arranmore.
The Irish Parliament formally recognized Boylagh as an independent barony in 1791 when it separated from the combined territory of Boylagh and Banagh. This administrative decision shaped the boundaries that define the region today.
The name Boylagh comes from the Irish word Baollaigh and traces back to the O'Boyle clan that shaped this region for centuries. You can still feel this connection today through the local place names and the way people talk about their land.
The area divides into four civil parishes with Dungloe and Glenties as the main towns where visitors find supplies and information. These two settlements serve as good bases for exploring the wider region.
The territory holds around 300 lakes scattered across its landscape, making it one of Ireland's most lake-rich areas relative to its size. This abundance of water comes from the region's glacial past and the porous granite bedrock that traps and stores water naturally.
