This medieval ringwork castle, dating back centuries, sits just 175 metres southwest of Kenny church and its associated graveyard, with Kenny House and its farmyard a mere 25 metres to the east. The monument first appeared on the 1837 Ordnance Survey map as a circular earthwork, and by the 1913 edition, its perimeter had already been incorporated into the local field boundaries that stretch from northeast through east, south, to southwest.

The structure consists of a large circular mound or platform, measuring approximately 28 metres from north-northeast to south-southwest and 27 metres from northwest to southeast. It’s enclosed by three distinct features: an inner bank, a deep intervening fosse (defensive ditch), and remnants of an outer bank. The inner bank remains high and steep, though modern pathways now lead up into the interior at various points. The fosse, still wide and deep, remains visible around most of the perimeter from northeast through to north, though it has been filled in along the northern section. Where the fosse’s outer edge meets the modern field fences, a stone facing has been built against it, and a narrow causeway, possibly a later addition, crosses the fosse at the southwest point.

Today, the monument appears as a tree-covered circular earthwork, its interior sloping downward from the edges towards an irregular depression in the centre; the western and northwestern sides show particularly sharp descents. The outer bank survives only along the western to west-northwestern section, a testament to centuries of agricultural activity and landscape change. Modern aerial photography clearly shows the distinctive circular shape of this defensive structure, which once served as a strategic stronghold in medieval Westmeath, controlling the surrounding lands from its elevated position on the ridge.
