This circular, grass-covered structure measures approximately 36 metres north to south and 28 metres east to west at its base, whilst the flattened summit spans 19 metres east to west and 13 metres north to south. The mound’s height varies considerably depending on the approach; rising 2.3 metres at the northeast and 3.7 metres at the southwest where it crosses the ridge, whilst reaching 5.5 metres at the southeast and an impressive 8 metres at the northwest.

The monument is defined by a fosse, or defensive ditch, that runs from east-northeast to south-southeast across the ridge, measuring 9 metres wide at the top with an internal depth of 2.1 metres and an external depth of 0.5 metres. Along its southwest to western edge, the site is bordered by the remains of an old field bank running northwest to southeast, which measures 2.5 metres in width and stands between 0.3 and 0.7 metres high. These features combine to create a substantial earthwork that would have been both defensively practical and visually commanding in its landscape setting.

Whilst the exact origins and purpose of Ginnets Moat remain subject to archaeological interpretation, its position on the esker ridge and defensive characteristics suggest it may have served as a ringfort or similar fortified settlement typical of early medieval Ireland. The site was formally recorded in the Archaeological Inventory of County Meath in 1987, with subsequent revisions incorporating recent research findings, most recently updated in March 2023.
