A shallow depression, no deeper than eighteen centimetres, traces a faint east-west line across the grass. It is almost nothing, and yet it appears to be the last visible remnant of a hollow trackway, a route worn down by repeated passage over centuries until the ground itself subsided along the line of travel.

The trackway was clear enough to be recorded on the first edition Ordnance Survey six-inch map of 1840, and it was still present when the revised edition was produced between 1903 and 1904. Running east to west immediately south-west of a concentric enclosure nearby, it formed part of a small cluster of earthworks in this corner of Tipperary. A second linear earthwork ran roughly north to south, meeting the outer bank or fosse of the concentric enclosure at its southern quadrant. A concentric enclosure is exactly what it sounds like, a series of roughly circular banks and ditches arranged one inside the other, a form often associated with early medieval settlement or land management in Ireland. A further enclosure and earthwork were recorded about a hundred metres to the north. Together, these features suggest a modest but organised early landscape, with defined routes connecting what may have been a significant enclosed site.

Since those map surveys, the field has been reclaimed for modern agricultural use, and the earthworks have been effectively erased. Only that slight hollow persists in the east-west line, shallow enough to be overlooked entirely underfoot, the kind of thing that only makes sense once you know what you are looking at.
