It measures roughly 7.6 metres north to south and 10.8 metres east to west, rising only 0.35 metres above the surrounding ground. That modest profile, though, is precisely what makes it worth attention: this is a fulacht fia, one of the most common and least understood monument types in the Irish archaeological record.

Fulachtaí fia are ancient burnt mound sites found in their thousands across Ireland, typically dating to the Bronze Age, though some extend into later periods. The accepted interpretation is that they functioned as cooking sites, where stones were heated in a fire and then dropped into a water-filled trough to bring it to the boil. The characteristic dark, burnt material that forms the mound is the accumulated debris of those stones, split and discarded after repeated heating. The site at Cloonyclohassy sits at the foot of an east-facing slope, immediately south-east of a relict field boundary, one of those ghostly lines in the landscape that marks a long-vanished system of land division. The location is characteristic: fulachtaí fia are almost always found near water or in low-lying, seasonally wet ground, and the marshy pasture here would have provided a reliable water source. What adds further interest is that another fulacht fia lies immediately to the south-east, catalogued as a separate monument, suggesting this corner of County Limerick saw repeated or sustained use across some stretch of prehistoric time.

The site is on agricultural land, so access would require the landowner's permission. The ground is described as marshy, so appropriate footwear matters more than the season, though the monument is likely most visible in late autumn or winter when vegetation is lower. Once you are standing beside it, the mound is subtle rather than dramatic; a slight rise in the field, dark in colour if exposed, unremarkable to an unprepared eye. Knowing what lies beneath, the accumulated residue of fires lit and stones shattered over Bronze Age meals or gatherings, gives the ordinariness of the place a different quality. The relict field boundary nearby is worth noting too, a reminder that the landscape around this mound has been shaped and reshaped by human hands across a very long span of time.
