At Lisgaugh, a possible ditch-barrow, a type of funerary mound defined and enclosed by a surrounding ditch, appears to have survived not as an earthwork in the conventional sense but as a feature slowly transformed by centuries of groundwater and reclamation into something that now reads, from the air, as a small body of standing water.

The site sits on land that was recorded as marshy ground on the first edition Ordnance Survey six-inch map of 1840, which gives some sense of how waterlogged this area has long been. That same map places the site in the company of a stepped barrow, a monument with a tiered or terraced profile rather than a simple mound, located around 140 metres to the south and recorded separately in the archaeological record. The ditch-barrow itself was identified from a Google Earth orthoimage taken in May 2000, on which the outline of the enclosing ditch was still faintly legible. By the time a later orthoimage was captured in November 2018, the feature had become fully visible as a pond. The research was compiled by Caimin O'Brien, drawing on details provided by Alison McQueen and Vera O'Rahilly, and uploaded to the record in September 2020.

The site is on reclaimed agricultural pasture, so there is no public monument to inspect at ground level, and the feature is most meaningfully observed through aerial or satellite imagery rather than on foot. Anyone with a particular interest in cropmark or soilmark archaeology, where buried or degraded features reveal themselves through changes in vegetation, soil colour, or water retention, will find this a useful case study in how ancient monuments persist in the landscape in altered and unexpected forms. The neighbouring stepped barrow to the south is the more formally recorded of the two sites, and together they suggest this quiet stretch of Limerick farmland has a longer history of human use than its present appearance would imply.
