Enclosures
Somewhere in the woods of Ballytrasna, Co. Limerick, a roughly D-shaped earthwork was recorded on the Ordnance Survey's first edition six-inch map in 1840, annotated with the name 'Clashatloe'.
By the time the revised twenty-five-inch edition was published in 1897, it had vanished from the cartographic record entirely, replaced by the notation of a long scarp or cliff-face measuring approximately 70 metres along its NW-SE axis. Whether the earthwork was deliberately omitted, misidentified, or had simply become unrecognisable in the intervening decades is not clear. What survives on the ground is a feature that even trained surveyors have struggled to interpret.
When archaeologists from the Archaeological Survey of Ireland visited in 2008, dense vegetation prevented them from gaining proper access. What they could observe was a steep counterscarp, the outer slope of a ditch in an earthwork enclosure, measuring roughly 2.4 metres wide and 2.25 metres high, defining the western side of the feature. The southern portion of the interior was partially submerged in water. That combination of waterlogging and the overall form of the depression led the surveyors to raise the possibility that this may not be an ancient enclosure at all, but a former quarry. The 1840 OS map lends some weight to that reading: several quarry pits are shown in the immediate vicinity, to the east, south-east, and north-west. It sits 65 metres north-east of the townland boundary with Ballynagally, and remains visible in aerial imagery as a tree and scrub-covered area, identifiable in orthoimages taken between 2005 and 2018.
Access to the site is genuinely difficult. The vegetation that blocked the ASI survey team in 2008 shows no sign of thinning in more recent aerial imagery, and the waterlogged interior makes close inspection impractical in wetter months. Anyone curious enough to look should focus on the western edge, where the counterscarp is the most legible element of the feature. The ambiguity is part of what makes it worth knowing about: a name on an old map, a shape that may be an enclosure or may be a quarry hollow, and a landscape that has largely swallowed the evidence either way.
