The National Monuments Service's description

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.
