This ditch-barrow in the townland of Oldtown (Bennett), County Limerick, is visible not by walking the land but by scrutinising aerial photography, where its circular outline appears as a cropmark against the surrounding reclaimed grassland. A ditch-barrow is a prehistoric funerary monument consisting of a low central mound enclosed by a surrounding ditch, the whole sometimes barely distinguishable from the earth around it after millennia of agriculture and drainage work.

The site sits in what the record describes as reclaimed poorly drained grassland, a landscape that has been substantially altered to make it agriculturally useful. That process of reclamation has done much to flatten and obscure what once stood here. A related monument lies roughly 43 metres to the south-southeast, and this barrow is considered part of a cluster of five possible ditch-barrows in the immediate area, suggesting the locality was used for burial or ritual purposes over a prolonged period. The faint outline of the mound was identified on Ordnance Survey Ireland imagery taken between 2005 and 2012, and again on Digital Globe photography from between 2011 and 2013, but it is a Google Earth orthophoto taken on 18 November 2018 that most clearly resolves the cropmark. The record was compiled by Caimin O'Brien and uploaded in December 2021.

There is little to see on the ground, which is part of what makes this site interesting as a category of monument. The evidence survives in the soil's differential moisture retention and in the way crops or grass grow slightly differently above a buried ditch, patterns only legible from altitude. A visitor to the area would be walking over agricultural land with no public right of access, so the satellite image is, practically speaking, the most accessible version of the site. The broader cluster of barrows in this part of Limerick is worth examining through aerial sources if prehistoric funerary landscapes are of interest, as the grouping implies something more deliberate than isolated burial.
