What is recorded here

This enclosure is situated at the SW end of Illanee or Garrison Island, in Lough Cullen c. 250m from its W shore. It consists of an impressive cashel-like monument (26m N-S; c. 24m E-W internally) built with stones bonded in mortar. Much of the mortar has eroded resulting in significant collapse of the enclosing walls in places. A possible two-roomed house is located in the NE quadrant of the enclosure and a small D-shaped hut abuts its SE gable. An entrance at the NW opens onto a rectangular berth for the mooring of boats: this now stands on dry land as the lake level was lowered in 1965. The monument has been identified by Naessens and O’Conor as a possible pre-Norman fortification dating to the eleventh- / twelfth century (2012, 119-121).
