What is recorded here

Onagh castle rose in 1238 as a blunt warning to Connacht, but Hugh O'Conor returned the favour in 1270 by burning it. Whether that is Dundonnell or a lost shadow beside it, the flame did its work and the boundary disappeared. Stone can resist arrows; it resists memory poorly. What remains is a place named twice, seen once, and erased by fire.

The castle of Onagh (Caislean Muille Uanach) was built in 1238 as a stronghold against the men of Connacht, and it was burnt by Hugh O'Conor in 1270 (A.C.). This may refer to Dundonnell ringwork castle (RO051-047001-) (Lynne 1985-6, 105; Curley 2011). Otherwise, it was not encountered. Compiled by: Michael Moore Date of upload: 24 August 2010

The castle of Onagh (Caislean Muille Uanach) was built in 1238 as a defensive stronghold against the men of Connacht, likely by a local Gaelic lord or Anglo-Norman settler. It is remembered for being burnt by Hugh O'Conor in 1270, reflecting the ongoing conflicts in the region during the 13th century.
