On a low, flat-topped hillock in the River Goul's plain in County Kilkenny, a small circular enclosure once occupied the ground, its outline captured on the first edition Ordnance Survey six-inch map of 1839. By the time the revision was published in 1900, it had disappeared from the cartographic record entirely, levelled sometime in the intervening six decades. Today, nothing of it is visible at ground level.

The enclosure was modest by any measure, roughly sixteen metres in diameter. Circular enclosures of this kind are a common feature of the Irish early medieval landscape, typically interpreted as the remains of ringforts, the enclosed farmsteads that once defined rural settlement across the country. What makes this particular example quietly notable is the precision with which its disappearance can be dated, or at least bracketed. The two OS editions, separated by roughly sixty years, mark its existence and then its absence, a small erasure that almost certainly reflects agricultural improvement or land clearance in the post-Famine decades, when the reorganisation of holdings across Ireland saw many such earthworks ploughed or levelled out of existence. The site sits about two hundred metres east of Foulkscourt Castle and its bawn, a bawn being the defensive walled enclosure that typically surrounded a tower house, and a further enclosure lies around a hundred and twenty metres to the north-east, suggesting this part of the Goul valley was once a more densely occupied landscape than its present flatness implies.
