This one in the Kilpeacon townland of County Limerick offers almost nothing to the eye at ground level, and yet its outline, glimpsed from the air decades ago, was enough to place it on the archaeological record. It is a site defined almost entirely by its elusiveness.

The enclosure, a term used here in the broad archaeological sense of a bounded area whose original purpose, whether domestic, agricultural, or ritual, remains unspecified, was not recorded on the Ordnance Survey six-inch map of 1840 or the more detailed twenty-five-inch survey of 1897. It came to light only in 1986, when aerial photographs taken at a scale of 1:10,000 for Bord Gáis Éireann during survey work for the Curraleigh to Limerick gas pipeline revealed its outline. Catalogued as BGE AP No. 30, Site No. 022201, it sits in low-lying undulating pasture on a slight west-facing slope, positioned 22 metres north of the townland boundary with Newtown and 190 metres east of the boundary with Skehanagh. When the Archaeological Survey of Ireland visited in 2000, the description was notably spare: the site lay atop a dry rise within otherwise wet pasture, with no surface remains visible whatsoever. A faint outline of the possible enclosure reappeared on an Ordnance Survey orthophoto taken between 2005 and 2012, but by 2020 it had vanished again from Google Earth imagery entirely.

For anyone drawn to the quieter end of the archaeological spectrum, reaching this site means navigating ordinary farmland in south County Limerick, where the most useful guide is the aerial photograph held in the Bord Gáis Éireann archive rather than anything visible underfoot. The dry rise that marks the location is subtle enough that even knowing where to stand offers little reward in most conditions. Aerial photographs taken after a dry summer, when soil moisture differences between a buried feature and its surroundings become more pronounced, are typically the best circumstances for cropmarks or soilmarks of this kind to reappear. Whether the outline ever resolves into something more legible may depend entirely on the weather, the season, and the angle of the camera.
