It has been formally recorded as a monument, given a reference number, and acknowledged as a structure worth noting, yet the question of when it was built remains, officially, open. The designation "indeterminate date" is not as rare as it might sound in Irish archaeological recording, but it does place a building in an odd liminal category, too significant to ignore, too ambiguous to classify with confidence.

Lisbarreen is a small rural townland in Clare, a county whose landscape holds an unusually dense concentration of structures from many different periods, from prehistoric stone forts and early medieval ringforts to post-medieval farmhouses and estate buildings. Without more specific detail about this particular structure, it is difficult to say whether it represents a late medieval tower-house dependency, a post-Famine labourer's cottage, or something else entirely. The "indeterminate date" label typically arises when a building has been too altered, too ruined, or too poorly documented to allow surveyors to assign it confidently to a known period. It is, in a sense, a monument that has outlasted the memory of its own origins.
