The one at Carrownaboll in County Sligo is a quieter, more ambiguous presence. What survives is an oblong raised platform, roughly 28 metres along its north-east to south-west axis and 15 metres across, sitting on a rise above a waterlogged hollow on a south-facing slope. A scarp, the steep face left when surrounding ground has been cut away or has eroded, defines the site along its southern and western edges, dropping between 1.4 and 2.8 metres. That is effectively all that remains to read.

A rath, to use the Irish term, was typically a roughly circular enclosure defined by an earthen bank and an outer ditch, or fosse, used during the early medieval period as a farmstead or high-status residence. Here, neither bank nor fosse survives. The perimeter has been largely quarried away, and the original entrance is no longer recognisable. What the quarrying removed, and when, is not recorded, but the loss is substantial. The oblong shape that remains is slightly unusual; most examples tend toward the circular or oval. Whether that reflects the original design or simply what survived the stone-robbing is impossible to say with confidence. The site sits just above marshy ground, a common enough placement for early medieval settlements, where elevated, well-drained ground was chosen deliberately over the wet terrain below.
