What makes the one at Knockgraffon quietly compelling is its position: set on a steep-sided hillock rising above flat farmland in County Tipperary, it commands unobstructed views across the surrounding countryside to the south-south-west, west, and east. That vantage point was almost certainly the point. Whoever chose this spot was making a deliberate statement about visibility, both outward and inward.

The enclosure measures roughly 32.5 metres north to south and 30 metres east to west, defined by an earthen bank approximately five metres wide. The bank incorporates large blocks of limestone, giving it a mixed character somewhere between a purely earthen construction and a stone-founded one. Externally it still stands to about 1.25 metres, though internally it has been worn down to around 0.4 metres in places. Three breaches have opened up over centuries of use and erosion, at the north-west, east-south-east, and south, ranging from 2.5 to 3.8 metres wide. Thorn trees have taken root along sections of the bank, as they so often do on earthworks left undisturbed. Inside the enclosure, the remains of a small semi-circular hut site survive, the kind of modest domestic structure that points to this being a place where someone actually lived, rather than a purely defensive or ceremonial construction. The site is not isolated in the landscape either; a related enclosure lies roughly 160 metres to the north-east, and a further ringfort sits about 270 metres to the south-east, suggesting this part of Tipperary was once a more densely settled and organised territory than the open pasture surrounding it today might suggest.
