What is recorded here

Donnachad Cairprech Ó Briain raised a circular earthen hold on the north bank of the River Fergus around 1210, forcing his people to wade water or find bridges whenever they visited. The castle vanished before 1267, when a new residence appeared across the river, suggesting the old ringwork became useless, dangerous, or simply forgotten.

On the N bank of the River Fergus opposite the site of Clonroad Castle (CL033-085001-) but not precisely located. An earthen fortification built in AD c. 1210 by Donnachad Cairprech Ó Briain and described in the Caithréim Thoirdhealbhaigh (cited in Ó Dálaigh 1987 and 2012) as a ‘circular hold and residence’. A new residence was built on the S side of the river in c. 1267. (Ó Dálaigh 1987, 20-22; 2012, 15) Compiled by: Mary Tunney Date of upload: 23 April 2014

Built around AD 1210 by Donnachad Cairprech Ó Briain, this ringwork in Lifford served as a strategic defensive structure during the Anglo-Norman expansion in Ireland. It is remembered for its mention in the *Caithréim Cellacháin*, highlighting its historical and literary significance.
