Field boundaries press in from the north-west, north, and south-east, so that the enclosure now reads less as an ancient monument than as an awkward corner of pasture that farmers have long since agreed to leave alone. That awkwardness, it turns out, is precisely what has preserved it.

Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically dating from roughly the fifth to the twelfth century. They consisted of a circular area enclosed by one or more earthen banks, and served as farmsteads for a single family and their livestock. The example at Graigacurragh is roughly circular in plan, measuring 32.1 metres north to south and 28 metres east to west. Its earthen bank survives to an internal height of 1.2 metres and an external height of 2.5 metres, the difference reflecting the way material was piled up from a surrounding ditch to create a defensive or boundary profile. The site sits on low-lying pasture ringed by higher ground on all sides, and a marshy natural dip adjoins the outer face of the bank to the east, a feature that may well have added to the site's original sense of enclosure and security. The record was compiled by Denis Power and uploaded in August 2011, with aerial photography captured by the Airborne Survey Instrument in October 2002 providing additional documentation.

Visitors should approach the bank from the north-north-east, which is noted as the most accessible point; elsewhere, heavy overgrowth masks the earthwork considerably, and the north-east section has been noticeably denuded. The interior, though level, is now occupied by mature coniferous trees, and fallen branches cover much of the ground surface, making any exploration slow and requiring care underfoot. The marshy ground along the eastern exterior is worth noting before you step off the bank in that direction, particularly after wet weather, which in Limerick is a reasonable expectation at most times of year.
