The relationship between the two is the point of interest: the footings may represent a third structure in a trio of early ecclesiastical buildings, one whose name, the Court or Hall of St. Brigid, appears in medieval and early modern sources but whose physical remains have never been firmly identified.

The site at Killare was founded by Aedh Mac Bricc, an early Irish saint, who is credited with establishing three buildings there: St. Aedh's Church, Temple Brigid, and a structure referred to in Latin sources as an 'aula', meaning a hall or court, of St. Brigid. Writing in the seventeenth century, the Franciscan scholar John Colgan recorded all three, describing the first as parochial, the second as Temple Brigid, and the third as the Court of St. Brigid. Colgan's account was later cited by Woods in 1907, and the medieval monastic survey by Gwynn and Hadcock, published in 1970, also places the 'aula' at Killare. The small ruined structure, aligned along precisely the same axis as the adjacent Temple Brigid, has been proposed as the physical candidate for this court or hall. It remains a possibility rather than a certainty, but the combination of the alignment, the proximity, and the documentary tradition makes it a plausible one. A plan of the church, holy well, and this possible ecclesiastical building was produced by surveyors in 1985, and the monument currently holds a preservation order under national monuments legislation.
