This one in Coolalough, County Limerick, offers nothing so obliging. The earthwork exists, for practical purposes, only in a single aerial photograph taken in 1986, and in the official record that photograph generated. Walk the ground today and you will find rough, wet pasture and nothing more.

The site sits approximately 45 metres south of the River Mahore, which here marks the boundary between the townlands of Coolalough and Oldtown. It was identified during the Bruff aerial photographic survey of 1986, recorded as reference Bruff 7, AP 5/2079, as a possible enclosure. An enclosure in this context typically means a roughly circular or oval area once defined by a bank, ditch, or both, the kind of feature that turns up across the Irish landscape in many forms and periods, from prehistoric settlements to early medieval farmsteads. The site never appeared on Ordnance Survey Ireland historic maps, which suggests it was already invisible at ground level by the time detailed mapping began in the nineteenth century. A ditch barrow, a type of burial monument defined by a surrounding ditch, lies about 80 metres to the west, catalogued separately as LI040-037004, hinting at a broader pattern of early activity in the area. Subsequent examination of OSi orthophotos and Google Earth imagery has failed to recover any trace of the feature, leaving the 1986 photograph as the sole direct evidence.

There is, in honest terms, very little to see here for the casual visitor. The surrounding land is rough and wet, and access would require care and appropriate footwear. The site is noted on the Record of Monuments and Places, which affords it legal protection regardless of its invisibility. For those interested in the archaeology of the Bruff area more broadly, the nearby townland boundary formed by the River Mahore is at least walkable, and the landscape context, low-lying pasture close to a minor watercourse, is itself typical of the kind of setting where early enclosures are often found in the Irish midlands and south. The 1986 aerial photograph, referenced in the compiled record by Martin Fitzpatrick and uploaded to the national record in August 2021, remains the starting point for anyone wishing to investigate further.
