The northernmost of the three is a ringfort, a type of roughly circular enclosure used as a farmstead or defended homestead during the early medieval period, typically between the fifth and twelfth centuries. What makes this particular example quietly interesting is not any single dramatic feature but the cumulative strangeness of the grouping: three monuments in deliberate alignment, the relationships between them still not fully understood, sitting in ordinary agricultural land south of Ballyneety House and just thirty-five metres west of a stream.

The site carries a small puzzle in its documentary record. When the first edition of the Ordnance Survey six-inch map was produced in 1840, this ringfort does not appear on it, though it is clearly shown on the later twenty-five-inch edition as a roughly circular platform, measuring approximately twenty-seven metres north-west to south-east and twenty-three metres north-east to south-west, enclosed by a bank, with a well marked ten metres to the east. When the Archaeological Survey of Ireland examined it in 2007, the surveyors recorded a raised circular area of around seventeen metres in diameter. The enclosing bank, fosse (a ditch encircling the central platform), and outer bank were still discernible, though much reduced. The fosse was best preserved on the north-east to north-west arc, while the north-east section had been cut through by a later land drain running east to west. Breaches in the enclosure at the south-east and south-west, one of them nearly twelve metres wide, suggest the site has seen considerable disturbance over time.

The ringfort sits in working farmland, so access depends on the usual courtesies of the Irish countryside: identifying the relevant land and seeking permission where necessary. The site is visible on aerial imagery, appearing as the furthest north of the three adjoining earthworks, and Google Earth orthoimagery from November 2018 shows its circular outline reasonably clearly from above. On the ground, the earthworks are low and somewhat worn, so patience and good light are useful; early morning or late afternoon, when shadows are longer, tends to make subtle earthwork topography easier to read. The well noted ten metres to the east on the older map is worth looking for, as water sources frequently appear in association with early medieval enclosures and may preserve their own quiet history.
