It was recorded on the first edition Ordnance Survey six-inch map of 1839 as a roughly square feature, approximately 27 metres north-west to south-east and 30 metres north-east to south-west, with a field boundary running along its north-eastern side. By the time the map was revised in 1900, the cartographers were already reading the site differently; the hachures, the fine lines used to indicate slopes and hollows, suggest a depression in the ground rather than a defined enclosure with upstanding edges. The site sits low and flat in a valley prone to waterlogging, which may explain some of that ambiguity, as well as much of what happened to it later.

A field visit in 1994 confirmed what had been suspected: land reclamation work had removed the enclosure entirely, or at least removed any trace of it visible at ground level. Yet satellite imagery examined in 2018 appears to show something still there, heavily overgrown but present in outline. The classification of the site, whether it was a simple agricultural enclosure or something older and more purposeful, has never been firmly settled, and the physical record has not made that easier. Some 70 metres to the north-east sits a ringfort, a type of enclosed farmstead common in early medieval Ireland, typically defined by one or more earthen banks and ditches. Whether the two features were ever related in use or date is not known. What can be said is that the valley holds at least two monuments of uncertain age and that one of them has spent the last thirty years technically absent but not quite gone.
