At Ballycummin in County Limerick, two modest structures appeared on the first edition Ordnance Survey six-inch map of 1840, drawn during that extraordinary national mapping effort which gave Ireland one of the most detailed cartographic records in nineteenth-century Europe. Their presence on the map suggested age, but exactly how much age was another question, one that eventually prompted a formal archaeological investigation to settle the matter.

The excavation was carried out by archaeologist James Eogan under licence reference 96E380-AR15, as part of the wider Adare-Annacotty Road Improvement Scheme, a road upgrade project that brought archaeological scrutiny to a stretch of the Limerick landscape. Road schemes of this kind routinely uncover far older remains, from prehistoric pits to early medieval enclosures, so the investigation of these two buildings was a reasonable precaution. The findings, however, pointed firmly to the nineteenth century. Whatever the structures had been, whether agricultural outbuildings, labourers' cottages, or something more domestic, they belonged to the period in which they were first recorded, rather than to any earlier layer of occupation the soil might have preserved.

Ballycummin today sits in the expanding southern suburbs of Limerick city, an area substantially altered by modern development. The road improvement scheme that prompted this investigation was itself part of that transformation. Visitors with an interest in the findings will not encounter a visible ruin or a preserved site; the record here is largely archival, held within the excavation report compiled by Denis Power and uploaded to the national monuments database in February 2013. For those researching vernacular architecture or the ordinary rural housing of nineteenth-century Munster, that report, modest in its conclusions, is nonetheless part of a larger picture of how people lived and built in the decades before and after the Famine, in a landscape that has since been almost entirely reshaped.
