On a south-facing slope in Kilcurly, in the old barony of Pubblebrien in County Limerick, a near-perfect circle has been holding its shape in the pasture for somewhere between one and two thousand years. Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically enclosing a single farmstead and its outbuildings within a raised earthen bank. This one is modest in scale but precise in form, measuring roughly 25.5 metres north to south and 26 metres east to west, making it almost exactly circular.

The enclosure works in two distinct ways depending on which side you approach. Along the south-west to north-east arc, the boundary is formed by an earth-and-stone bank, standing about 0.6 metres high on the interior and slightly less on the exterior. Swing around to the north-east to south-west side, however, and the boundary becomes a scarped edge, where the ground has been deliberately cut into the hillside to create a near-vertical face rising 1.25 metres, with a width of around 3.7 metres. This combination of built bank and cut scarp is a practical response to the slope, using the natural lie of the land to reinforce the enclosure without unnecessary labour. The interior follows the gradient of the surrounding terrain, sloping gently downward toward the south. The site was compiled by Denis Power and recorded in the national monuments survey, with details uploaded in August 2011.

Access is across farmland, so the usual courtesies apply; speak to the landowner before crossing any field boundaries. The monument sits just below the brow of the hill, which means it is not immediately visible from the road, and the approach involves reading the landscape carefully rather than following any obvious path. Much of the interior and the bank itself is overgrown with bushes, briars, and nettles, which can make the dimensions difficult to appreciate in summer. A visit in late autumn or winter, when the vegetation has died back, gives a cleaner sense of the earthwork's shape and the relationship between the scarped edge and the built bank. Look for the change in character between the two sides of the enclosure; that shift from constructed wall to cut hillside is the most legible thing about it.
