The castle ruins are concentrated primarily on the southern side of the enclosure, with a series of walls extending northward and westward. At the heart of the site lies an uneven mound measuring approximately 16 metres north to south and 22.4 metres east to west, covered in sod and stone that likely represents the collapsed masonry of the original castle structure. Large sections of masonry remain visible at the base of the steep southern side, though vegetation has partially obscured much of the mound over time.

The architectural footprint reveals a complex defensive layout through its surviving wall foundations. A linear wall, roughly 2 metres wide and standing 0.2 metres high on the interior side and 0.45 metres on the exterior, extends about 16 metres along a north-south axis to the east of the main mound before turning at a right angle westward for another 5.5 metres. A metre-wide break near the western end suggests a possible doorway, and the wall then turns northwest for 1.5 metres where it meets another internal wall. Additional fortifications include a 6-metre wall running northwest to southeast from the castle mound, which then turns west and continues for 18 metres until it reaches the inner wall of the main castle enclosure.

Historical records paint a picture of a once-significant fortification that had already fallen into disrepair by the mid-17th century. The Civil Survey of 1654-56 describes it as a ‘broken castle’, indicating its ruined state even then. According to historian O’Flanagan’s 1930 account, the site contains fragmentary masonry remains and traceable foundations within what he described as a large trivallate enclosure; a sophisticated triple-walled defensive system that speaks to the strategic importance this location once held in medieval Tipperary.
