What is recorded here

Knockmaria Castle stands as a ruined tower house on a low hill in County Mayo, overlooking Addergoole church and the waters of Lough Conn. Only its eastern angle survives, built of coarse limestone with a rubble core, rising about three and a half metres above the rolling countryside. The structure appears on old maps as a castle in ruins, marking a forgotten defensive presence near the Addergoole River.

Situated on a low but prominent hill in rolling countryside. The Addergoole River is 200m to W and an inlet of Lough Conn is just over half a kilometre to E. It overlooks Addergoole church (MA047-018001-), a late medieval parish church, which is located on the lake shore 750m to NNE. Indicate on the 1838 and 1922 OS 6-inch maps as ‘Castle in Ruins’, only the ENE angle (5m NNE-SSW; 3.3m WNW-ESE) of this tower house is still standing. The surviving walls are constructed of roughly coarsed limestone with a rubble core and stand to a height of c. 3.5m. Compiled by: Jane O'Shaughnessy Date of upload: 28 July 2022
