The one at Bishopscourt in north Kerry does almost none of this. It sits between two large pastoral fields on a south-facing slope, and to any casual observer it has all but vanished. Centuries of farming, ploughing, and the slow settling of the land have levelled it almost entirely, leaving a faint rectangular footprint that only reveals itself on close inspection.

The enclosure is unusually large, measuring roughly 52 metres from north to south and 97 metres from east to west, making it considerably bigger than the typical early medieval ringfort, which tends to be roughly circular and far smaller. Its rectangular form is itself a point of interest; rectangular enclosures are less commonly recorded than their circular counterparts and may reflect a different function, period, or cultural influence, though the surviving evidence at Bishopscourt is too eroded to say much with confidence. A fieldbank running north to south now cuts the whole thing in two, effectively dividing what was once a single enclosed space into two halves that belong to the surrounding fields rather than to any legible ancient structure. The western sector survives in the best condition, with the enclosing bank measuring around 12 metres wide at its base and approximately half a metre high on both its inner and outer faces, sloping so gradually into the surrounding ground that the transition is easily missed. The site was documented as part of the North Kerry Archaeological Survey, published in 1995 by C. Toal.

For anyone visiting with an interest in finding it, the western bank is the most likely place to detect any variation in the ground surface, but patient observation in low morning or evening light, when shadows pick out subtle earthworks, gives the best chance of reading the outline at all.
