Not demolished, not built over, simply swallowed by vegetation to the point where its outlines are almost impossible to read from ground level. It is the kind of monument that rewards patience and a good map more than it rewards casual curiosity.

A ringfort, or rath, is an enclosed circular or oval settlement of early medieval date, typically defined by one or more earthen banks and ditches, and used as a farmstead or place of protection. The Ballinlongig example was recorded on the Ordnance Survey six-inch map of 1924 as a roughly circular enclosure approximately thirty metres in diameter. When Denis Power compiled his survey notes, uploaded in August 2011, the monument had become completely covered by dense overgrowth, making a full assessment difficult. What could be established was that it is enclosed by a low earthen bank with a shallow external fosse, the fosse being the ditch that typically runs around the outer edge of such enclosures, separating the interior from the surrounding ground. The combination of low bank and shallow fosse suggests a modest example of the type, though the vegetation obscuring it makes any further reading of the site speculative.

The site sits in level pasture, which means the surrounding ground gives few natural landmarks to orient a visitor. The 1924 OS six-inch map remains the clearest documentary evidence of its shape and position, and consulting a historical mapping resource before setting out would be sensible. Access to the land would require the permission of the landowner, as is the case with most ringforts on private agricultural ground in Ireland. The dense overgrowth noted in the survey record may well have thickened further since 2011, so locating the bank and fosse beneath it requires careful attention to subtle changes in ground level rather than any obvious visual feature.
