First recorded on the 1837 Ordnance Survey map, this grass-covered platform measures approximately 21 metres northwest to southeast and just under 9 metres across, surrounded by a complex system of water-filled ditches that once provided both defence and drainage.

The site’s most striking features are its well-preserved moats, which create a series of concentric boundaries around the central platform. The inner moats, reaching depths of about 0.8 metres and spanning 5 metres at their widest point, are separated from an outer defensive ring by a 2-metre-wide earthen walkway called a berm. These outer moats, though shallower at just 0.3 metres deep, would have created an additional barrier against unwanted visitors. Whilst the northwestern moats have long since disappeared and the southwestern edge now meets directly with the river, the surviving earthworks paint a clear picture of the site’s original rectangular footprint, which once stretched 30 by 20 metres at its fullest extent.

At the heart of the platform lies a curious shallow depression, measuring roughly 14.6 by 6.6 metres and sunk just 0.2 metres below the surrounding ground level. This feature likely marks the location of a timber hall or dwelling that once stood here, possibly dating to the Anglo-Norman period when such moated sites were commonly built across Ireland. These fortified homesteads served as administrative centres and symbols of authority for colonial lords, combining practical defence with the status that came from controlling the surrounding landscape.
