The site at Dromalta was identified through the Bruff Survey, one of the systematic aerial reconnaissance projects that have logged hundreds of otherwise unrecorded earthworks across Munster, and what it shows is a roughly subrectangular shape, oriented northwest to southeast, measuring approximately fifty metres by forty metres.

The enclosure was recorded in detail by Doody in 2008, who noted a possible entrance on the western side and traces of what may be an internal bank. Enclosures of this kind, defined by a bank and sometimes a ditch, were used throughout prehistoric Ireland for a variety of purposes, from settlement to stock management to ceremonial activity. The particular shape and proportions here, subtly different from the more regular ringforts associated with the early medieval period, suggest a Bronze Age date, a broad span running roughly from 2500 to 500 BC. Ringforts, by contrast, the circular farmstead enclosures that dot the Irish countryside in their thousands, tend to be more uniformly circular and are generally associated with the first millennium AD. The morphology at Dromalta places it in an earlier and considerably less well-documented tradition.

The site is catalogued under the Bruff Survey reference Map 15, no 21.2, and carries the national record number 4/3729. Because it survives primarily as a cropmark or soilmark, meaning that it shows up in dry summers when differential moisture causes the vegetation above buried features to grow or wilt at slightly different rates, there may be little to see during a casual visit at ground level. Any visible earthwork remaining would be subtle. The surrounding farmland in this part of Limerick is gently rolling and largely under grass or tillage, which is precisely the kind of terrain where aerial survey has been most productive. Anyone researching the site in advance would do well to consult the National Monuments Service Record, where the aerial evidence is archived.
