The site consists of a raised oval mound measuring approximately 40 metres north to south and 30 metres east to west, rising about four metres above a surrounding fosse. This defensive ditch, roughly two metres wide, encircles the mound alongside a substantial earthen bank that reaches 1.9 metres in external height and spans eight metres in width. The fortifications are best preserved along the northeastern, eastern and southeastern sections, whilst the fosse has been filled in elsewhere over the centuries.

The castle’s defensive features include a two-metre-wide causewayed entrance on the eastern side, providing controlled access to the elevated interior where an 18th or 19th-century folly now stands at the centre. Recent archaeological investigation has revealed additional structures through aerial photography and satellite imagery. A 1989 aerial photograph first showed cropmarks indicating a sub-rectangular bailey extending northwest from the main ringwork, measuring roughly 150 metres northwest to southeast and 140 metres northeast to southwest. Google Earth imagery from April 2021 confirms these features and reveals an additional outer fosse running approximately 40 metres from the primary fortification, encircling it from northeast through east to south.

The site has yielded other archaeological discoveries, most notably in 1838 when gravel extraction on a spur extending eastward from the ringwork uncovered a flat cemetery, though its precise location remains unknown. The combination of the ringwork’s strategic hilltop position, its well-preserved earthworks, and the recently discovered bailey marks Danesfort as a significant example of Anglo-Norman fortification in County Kilkenny, likely dating to the late 12th or early 13th century when such structures were commonly built to control and defend newly conquered territories.
