It sits in rough reclaimed pasture near Tankardstown in County Limerick, part of a loose cluster of barrows, and its existence was not formally noted until someone looked closely at aerial photographs taken in November 1984. That is not an unusual story for this class of monument, but it is a useful reminder that the landscape holds considerably more than the maps admit.

A ditch barrow is a circular burial monument defined by a surrounding ditch, typically prehistoric in origin, though the precise date of this example is not recorded in the available notes. The site, catalogued as Site No. 040235, was identified during examination of aerial photographs commissioned as part of the Bórd Gáis Éireann Curraleigh West to Limerick gas pipeline survey, using imagery from a series referenced as BGE 1/50000 2552. On those photographs it appeared as a small circular cropmark, a faint ring visible in the grass where the buried ditch causes differential growth above. It belongs to a group of related barrows in the same area, recorded under the monument numbers LI040-055003 through 006. A field boundary running immediately to the north is itself post-1700 in date, meaning the barrow predates the present agricultural organisation of this corner of Limerick by a very considerable margin.

The monument is situated immediately south of that field boundary in rough pasture, and later orthophotography, both from the Ordnance Survey Ireland series taken between 2005 and 2012 and from Google Earth imagery of a similar period, shows it as a D-shaped cropmark rather than the full circle visible in the 1984 photographs, possibly due to the proximity of the boundary affecting one arc of the ditch. There is nothing to see on the ground in any conventional sense; no mound, no marker, no signage. The site is not publicly listed on OSi historic maps. For those interested in cropmark archaeology or the wider distribution of burial monuments in the Limerick landscape, the aerial imagery remains the primary way of engaging with this one.
