That word "anomalous" in the official designation is telling; it signals that archaeologists were not entirely sure what to make of this arrangement, which is itself a reason to pay attention.

The site centres on a low earthen mound, roughly 5.2 metres north to south and 4.6 metres east to west, ringed by five stones. On its western side, three upright stones lean at pronounced angles, the tallest of them standing 2.1 metres high. On the eastern side, two stones lie prostrate, whether collapsed over time or never fully raised is unclear. Set apart from the mound, about 3.6 metres to the west, two further standing stones rise along a northeast to southwest axis, the taller reaching just over a metre. The reference goes back to O'Brien, writing in 1970, who recorded the arrangement but did not resolve what it represents. The combination of a mounded earthwork with encircling stones and a separate pair of standing stones nearby evokes the grammar of prehistoric monument-building, where mounds marked burials and standing stones served ritual or territorial functions, but the precise syntax here remains ambiguous. West Cork has a well-documented concentration of prehistoric stone rows and circles, particularly of the distinctive Cork-Kerry type, yet this grouping does not conform neatly to those recognised forms, which is presumably why the classification stops at "anomalous stone group" rather than assigning it to a tidier type.
