The site came to light during test excavations carried out as part of the East–West Interconnector Project, a major infrastructure scheme that required archaeologists to examine the ground before cable-laying could begin. What they found was not simply a scattering of graves, but evidence that the burial area had once been deliberately enclosed, marked off from the surrounding landscape by a series of ditches.

The excavation, conducted under licence number 11E0235 and reported by Mullins in 2011, identified ditches running both to the east and west of the burials, recorded under the Sites and Monuments reference DU008-108001. The western ditch was particularly substantial in scale, and its fill contained charred grain, a detail that raises quiet questions about what activities were taking place nearby, whether the burning was incidental, agricultural, or connected in some other way to the use of this ground. Above the ditches and the burials alike, a layer of soil had accumulated that was rich with medieval potsherds and animal bone, suggesting that long after the enclosure had ceased to function as a defined space, the land continued to be occupied or worked during the medieval period. The relationship between the ditches and the burials is not certain; the excavators noted only that the ditches may have served to demarcate the burial area, leaving open the question of sequence and purpose.

The site is not publicly accessible as a monument in any formal sense; it was uncovered within a construction corridor and examined as a salvage exercise rather than preserved in place. Visitors to the Rogerstown estuary area, which sits between Rush and Donabate on the north Dublin coast, will find a landscape more notable for its wetlands and bird life than for visible archaeology. The significance of this particular spot lies underground and in archive, in the excavation records and the sherds and the charred grain that together suggest a managed, meaningful use of this ground at some point in the past, the precise date of which the available notes do not specify.
