Recorded as a monument but assigned no firm date, it occupies that peculiar category of structure that is significant enough to note yet still too obscure to fully explain. The demesne setting adds a layer of quiet strangeness: demesnes, the enclosed private landholdings that typically surrounded the great houses of the Anglo-Irish gentry, often accumulated outbuildings, gate lodges, and subsidiary dwellings across several centuries, making it genuinely difficult to assign a single date to every structure within them. This one, it seems, has so far resisted that assignment.

Eyrecourt itself takes its name from the Eyre family, who held land in this part of east Galway from the seventeenth century onwards. The most celebrated survival on the demesne is Eyrecourt Castle, a late seventeenth-century house long considered one of the more remarkable examples of Restoration-era architecture in Ireland, though it has been in ruin for well over a century. The demesne around it, like many such estates, would have supported a working landscape of ancillary buildings whose precise histories were rarely considered worth recording in detail at the time they were built. The house in question appears to be one of those structures, recognised as something worth registering but not yet fully understood.
