The site consists of an earthen mound, roughly 16 metres north to south and 24 metres east to west, rising about 3 metres at its highest point. Unlike the imposing mottes typically associated with Norman conquest, this example is relatively modest in scale and curiously positioned; surrounded by marshland on three sides with a river marking the townland boundary just 20 metres to the west. A sub-rectangular bailey, matching the mound’s dimensions but standing only about a metre above the surrounding field level, extends from its eastern side. The two structures are separated by a 4-metre-wide berm or trackway, with a 6-metre-wide defensive ditch running north to south beyond it.

Historical records first mention a stone castle at this location in 1441, when it belonged to Stanon, the first Lord of Knight. The castle served multiple purposes for the local nobility, most notably as a prison; in 1442, Walter De Burgo found himself confined within its walls by the Earl of Ormond, and forty years later, Walter Hackett faced threats of similar imprisonment. Despite these documented references to a stone structure, no masonry remains are visible today at ground level, leaving only the earthworks to hint at the site’s medieval significance.

The fortification’s strategic limitations are immediately apparent to any visitor. Its position offers only restricted views of the surrounding countryside, and its location at the very edge of the western foothills seems an odd choice for defence. The mound’s southern and western faces drop away steeply, whilst the northern and eastern slopes present a gentler gradient. Today, cattle use the bailey area for scratching posts, a mundane end for what was once part of the medieval power structure of South Tipperary. The nearby church and graveyard, located 173 metres to the southwest, suggest this was once a significant settlement, even if the castle itself never achieved the commanding presence of grander Norman fortifications elsewhere in Ireland.
