The site occupies a strategic position on a neck of land locally known as ‘The Island’, which earns its name from being surrounded by water on all sides; a stream flows east to west along its northern boundary, connecting the River Aherlow to the west and the River Suir to the east, with both rivers converging to the south. From here, the imposing Knockgraffon Motte can be spotted about a kilometre to the east-southeast, suggesting this area held considerable defensive importance during medieval times.

The monument has undergone significant changes since it was first recorded on the 1840 Ordnance Survey map, where it appeared as a roughly D-shaped enclosure. By the time of the 1901-05 survey, the eastern quadrant had already vanished, and today that portion has been completely levelled to accommodate a milking parlour running east to west through what was once the southeastern section. What survives is a D-shaped area measuring nearly 30 metres north to south, defined by a scarp standing almost 2.7 metres high, with the interior gently sloping towards the north.

Modern farming has left its mark on the site; water troughs have been built into the western base of the scarp, an electricity pole stands in the southern sector, and the southern edge has been cut back. The monument’s placement on a naturally steep-sided hillock, combined with the notable absence of a defensive bank typically found in ringforts, suggests this wasn’t a standard Irish ringfort but rather some form of medieval fortification, perhaps taking advantage of the naturally defensive position offered by the elevated ground and surrounding waterways.
