The circle at Carrigagulla is something else: a much larger, more ambitious structure sitting quietly in a level patch of pasture on the western edge of the Laney River basin, its scale and layout suggesting a community that invested considerably more effort in its construction than was strictly typical of the region.

The circle may originally have comprised seventeen uprights, of which fifteen survive. Among them are axial and radially-set entrance stones, features common to the recumbent stone circle tradition of Cork and Kerry, in which specific stones are positioned to frame or anchor a principal sightline. That axis runs ENE to WSW, with an internal span of 7.8 metres along its length. The surviving orthostats, the individual standing stones, range from 0.6 to 1.7 metres in length and reach heights of up to 0.9 metres. Unusually, a separate internal block sits directly on the main axis inside the ring, a low, broad stone measuring roughly 0.9 by 0.6 metres and standing 0.4 metres high. Its purpose is unclear, though comparable internal features at other sites have been interpreted as focal points or altar-like settings, though that word carries modern associations the archaeology does not quite support. The scholar Seán Ó Nualláin documented the site in 1984, placing it within his broader typological survey of Cork and Kerry circles. What adds another layer of interest is that a five-stone circle, the more common smaller type, stands roughly 380 metres to the north-north-east. The proximity of two structurally distinct circle types within sight of one another raises questions about how these monuments related to each other in use, in time, or in the minds of the people who built them, questions that have not been fully resolved.
