The site consists of a series of discontinuous stone banks that wind their way through six townlands; Gleninagh South, Ballconry, Newtown, Lismacsheedy, Lismacteige and Feenagh. First spotted by Sharon Parr during the BurrenLIFE project, subsequent archaeological work has revealed these grass-covered banks to be carefully constructed stone structures, built at three distinct levels on the hillside.

The banks primarily follow the natural contours of the hill between 260 and 270 metres, though the uppermost section sits on a natural terrace reaching up to 280 metres at the southeastern end. Two ancient cairns mark this upper level, though archaeologists suspect these stone monuments were added after the original banks were built. What makes this site particularly intriguing is the numerous gaps found throughout the circuit; some align with natural features like limestone terraces and depressions, whilst others were deliberately created and marked with upright kerbstones. These openings suggest the enclosure wasn’t built for defence, unlike typical hillforts.

Archaeological surveys indicate the monument shares characteristics with Neolithic banks found at Knocknarea in County Sligo, pointing to a much earlier date than initially suspected. Given its position overlooking two natural passes through the Burren Uplands, archaeologists now believe this massive enclosure may have served as a prehistoric gathering place, perhaps marking an important point along ancient routes through this remarkable limestone landscape. The sheer scale and careful construction of the banks hint at the significance this hilltop location held for our ancestors, though its exact purpose remains one of the Burren’s many mysteries.
