O'Boyle's Fort at Stonebrook

The reusable photograph record describes these curving stone remains at Stonebrook near Ardara as the fort of the O'Boyles and says the place was an O'Boyle stronghold. That account comes from the picture record. No matching official monument number was proven in the saved Donegal list, so this page keeps the photograph's point without claiming an official classification.

O'Boyle's Fort at Stonebrook is a likely early-medieval ringfort associated with the O'Boyle family, a prominent Gaelic clan in the northwest of Ireland. Local tradition holds it as a stronghold of the O'Boyles, reflecting both their territorial influence and the site's strategic or symbolic importance in the region.
