This is a rath, the commonest type of ringfort in Ireland, a form of enclosed farmstead typical of the early medieval period, generally dated between the sixth and tenth centuries. What makes this particular example worth a second look is a small engineering detail: the interior has been deliberately raised on its north-western side to level out the ground against the natural fall of the hillside. It is a practical adjustment, easily overlooked, but it speaks to the care taken by whoever laid out the enclosure.

The earthwork measures roughly 34 metres east to west and 33.5 metres north to south, making it a fairly standard size for a single-family farmstead of the period. The enclosing bank stands about 1.1 metres above the interior on its eastern side and rises to around 2 metres on its exterior face. To the west, the bank gives way to a scarp, a near-vertical cut face dropping some 1.5 metres, with a slight lip just inside. A shallow external fosse, essentially a ditch dug to provide material for the bank and to add a further obstacle, survives in part, though at only around 0.2 metres deep it has largely silted up over the centuries. A field boundary running from north-east to south-west has been built along the top of the bank at some point, which is a common fate for these monuments as later generations of farmers found a ready-made linear feature and simply incorporated it into their own land divisions.
