The structure presents as a roughly rectangular mound, standing just over 2 metres high and measuring approximately 21 by 15.5 metres at its base, tapering to about 15.5 by 10.3 metres at its summit. The northeastern side shows a distinctive narrowing, whilst the southwestern side and northwestern corner feature particularly steep slopes that would have made the fortification formidable in its day.

The most striking feature of the site today is a deep central depression, over a metre in depth, which unfortunately results from later quarrying activities that have disturbed much of the mound’s interior. This damage has made it difficult to fully understand the original internal layout of the castle, though the basic defensive structure remains clear. Despite careful examination, no traces of an outer fosse or additional defensive earthworks have been identified around the perimeter, suggesting this was likely a relatively simple fortification.

Ringwork castles like this one were common in medieval Ireland, particularly in the decades following the Anglo-Norman invasion of the late 12th century. They consisted of circular or oval defensive banks of earth and timber, often topped with wooden palisades, and served as fortified residences for the new colonial elite. The Shevry example, documented in the Archaeological Inventory of County Tipperary, represents one of many such sites scattered across the North Tipperary landscape, each telling a story of medieval power, control, and the transformation of the Irish countryside during this turbulent period.
