In a pasture on a south-facing slope at Baunoulagh in County Cork, there is a ringfort that exists now almost entirely as an absence. A ringfort, or rath, was a roughly circular earthwork enclosure used during the early medieval period, typically as a farmstead surrounded by an earthen bank and ditch. This one measures approximately 45 metres in diameter, and the only way to observe its outline today is from the air, where faint cropmarks, the differential growth of grass or grain above buried features, trace the ghost of its circular boundary.

The site was already in trouble when Bowman noted it in 1934, recording it as a levelled fort on Mr Bresnahan's land that was by then "scarcely discernible". The 1842 Ordnance Survey six-inch map had captured it more clearly, depicting the enclosure as a hachured circle, the standard cartographic shorthand for a raised or embanked feature. At some point between that survey and Bowman's visit, the earthworks were cleared, most likely to improve the land for grazing or tillage. What the aerial photograph catalogue reference GSIAP R721 preserves is essentially the memory of the bank pressed into the soil. A further ringfort survives in the same field, roughly 30 metres to the north, which raises the intriguing possibility that the two enclosures once functioned together, perhaps as related farmsteads within the same agricultural landscape. Paired or clustered ringforts are not unusual in Cork, though the reasons for their proximity, whether family ties, sequential occupation, or shared land management, are rarely recoverable from the ground alone.
