This is the story of Kilbarron Castle, its people, places and politics.

The Castle ruins are on the scenic wild Atlantic coast of County Donegal.

Kilbarron Castle was a late-medieval fortified tower house. With important links to the O’Donnells, who were rulers of Tir Conaill (Donegal), it was the home of the Ó Cléirigh (Cleary) sept in Donegal and the birthplace of Mícheál Ó Cléirigh, the chief author of the famous Annals of the Four Masters.
