It has been logged, assigned a monument record, and given a category, which is simply "house", with a date that amounts to a formal admission of uncertainty: indeterminate. That phrase, dry as it sounds, carries genuine archaeological weight. It means the structure has not been convincingly placed within any recognised period, whether early medieval, post-medieval, or otherwise, and that the physical or documentary evidence available so far has not resolved the question.

Killower is a small rural townland in east Galway, in a part of the country where the landscape holds an unusually dense record of human settlement across several millennia. Structures described as houses in archaeological inventories can range from the remains of early medieval homesteads associated with ringforts, to the collapsed walls of post-Famine cottages abandoned in the nineteenth century. The designation "indeterminate" suggests that whatever survives at this site, it has not yielded the diagnostic features, such as associated finds, construction technique, or documentary reference, that would anchor it to a particular era. It sits in the record as a known unknown, present enough to be counted, elusive enough to resist classification.
