The site sits strategically above sloping ground, with a stream flowing approximately 90 metres to the west and the River Nore winding through the valley some 400 metres to the south. This raised circular platform, measuring roughly 40 metres east to west and 44 metres north to south, rises between one and one and a half metres above ground level on its northern and eastern sides, whilst the western edge drops more dramatically by about three metres.

The most distinctive defensive feature is found on the southern approach, where a wide, flat-bottomed ditch, or fosse, measuring 3.5 metres across, curves around the platform. Beyond this, an outer earthen bank, four metres wide and half a metre high, provided an additional line of defence. The platform’s surface remains relatively flat with a gentle slope towards the west, though centuries of weathering have softened its military edges. Mature beech trees now ring the platform’s perimeter, with the southern trees growing on a stepped terrace that sits 0.4 metres below the main platform edge; this terrace, just 1.5 metres wide, may represent an original defensive feature or later modification.

Today, bushes and scrub have colonised the northern slopes, whilst some disturbance on the eastern side marks where old field boundaries were removed. The monument represents a type of early Norman fortification common in Ireland during the 12th and 13th centuries, when timber palisades and buildings would have crowned these earthwork defences. Scholar Neary documented the site in 2005, producing detailed plans and sections that help us understand how these ringwork castles functioned as both military strongholds and administrative centres in medieval Ireland.
